The world's number 1 dermatology information resource

Universally respected, Rook's Textbook of Dermatology is the most comprehensive, definitive and best-illustrated reference work for dermatologists of all levels worldwide and has been at the forefront of international dermatology publishing since first appearing in 1968.

The Ninth Edition has been radically re-engineered to match the modern day challenges faced by dermatologists. Once again it has been published as a combined digital and print resource, but with a new online platform enabling easier and faster navigation.

A common structure to describe and discuss each disorder has been adopted throughout, whilst maintaining the depth of information for which Rook is renowned. A high priority has been placed on the ease of extracting key information quickly: diagnostic algorithms and management ladders help the reader choose appropriate treatment strategies. More images than ever – over 5000 in total – aid diagnosis by displaying variations in disease manifestations according to body location, skin type and severity. The section on aesthetic dermatology has been greatly expanded with more coverage of procedures in this rapidly developing field.

Rook's Textbook of Dermatology, Ninth Edition provides you with:

  • The very best content from the number one brand in dermatology – an essential consultation tool for all dermatologists
  • An outstanding combined digital/print resource, exhaustively covering every dermatological disorder
  • A complete overhaul of its content – each disorder now follows a consistent templated approach
  • A fresh approach to the classification of disorders and organization of chapters, of which there are now 160 instead of 80, all organised into 14 logical sections
  • A newly designed sophisticated online platform with a fast and powerful digital search functionality – search by keyword, disorder or chapter or consult the online image database and get expert clinical advice more quickly than ever
  • Lavishly illustrated chapters with over 5000 colour images showing variation in disease patterns by body location, skin type and severity
  • Comprehensive coverage of medical, surgical and aesthetic dermatology, as well as the basic science underpinning the field
  • An experienced British editorial team working with distinguished international authors and associate editor
  • Greater emphasis than before on clinical studies/trials, society guidelines and the latest ICD codes
  • While key references remain in the printed version, thousands more are cited in the book and can be accessed online, where each is hyperlinked to the relevant text

Rook’s Textbook of Dermatology, Ninth Edition is the complete dermatology reference work. More comprehensive than ever, with more images, more disorders covered and faster, more dynamic and wider digital search functionality. It is an essential resource for the modern day dermatologist, whether experienced or at the beginning of a career in dermatology.

Figure 2.1

The skin and its appendages.

Figure 2.2

Embryonic development of the skin depends on specific signalling molecules. Relative stimulation or inhibition by these signalling molecules also determines whether embryonic epidermis progresses to a stratified epidermis or whether formation of skin appendages is induced. BMP, bone morphogenic protein; EGF, epidermal growth factor; FGF, fibroblast growth factor.

Figure 2.3

Scanning electron micrograph of an 85–110-day (estimated gestation age) human embryo. Single globular blebs project from the periderm cells.

Figure 2.4

Electron micrograph of the full-thickness epidermis from the back of a 14-week human fetus. The periderm cells are full of glycogen (g) and have microvilli (m) at their amniotic border. Cells of the intermediate layer (i) also contain glycogen. Basal layer cells (b) have lost glycogen by this stage. Just above the dermal–epidermal junction (j) there is a melanocyte (me); the surrounding space indicates that it is a recent immigrant from the dermis (d). Osmium fixation and lead staining.

Figure 2.5

Embryonic stages of hair follicle morphogenesis.

Figure 2.6

Photomicrograph of a 1 μm-thick plastic section of normal human skin. The tissue was fixed with half-strength Karnovsky medium and embedded in Epon. This technique allows the cellular components of the epidermis, including keratinocytes, melanocytes (straight arrows) and probable Langerhans cells (curved arrows) to be clearly resolved. Magnification 400× (basic fuchsin and methylene blue).

Figure 2.7

The process of epidermal differentiation is associated with the expression of different structures, macromolecules, transcription factors and other signalling molecules and their receptors in the different keratinocyte layers. EGFR, epidermal growth factor receptor; IGF, insulin-like growth factor; IGFR, IGF receptor; TGF, transforming growth factor.

Figure 2.8

Electron micrograph showing details of the upper part of the epidermis including the stratum corneum (SC), stratum granulosum (SG) and most superficial cell layer of stratum spinosum (SS). Note the irregularly shaped keratohyalin granules (kh) and the small, round, lamellar granules (lg). The latter are present in both SS and SG and are smaller than mitochondria (m). The inset shows details of lamellar granules.

Figure 2.9

Assembly of the epidermal cornified cell envelope. In response to increasing intracellular calcium, an internal scaffold of desmosomal proteins is made along the plasma membrane. The contents of lamellar bodies (ceramides and other fatty acids, cholesterol and cholesterol esters) are released into the extracellular milieu to form a lipid membrane. The developing envelope is then added to and reinforced by the recruitment of various proteins, including loricrin, small proline-rich proteins (SPRs), other desmosomal remnants and attached keratin filaments. The resulting cornified cell envelope is durable and flexible and provides important mechanical and barrier functions.

Figure 2.10

Electron micrograph showing the location of epidermal lipids by ruthenium oxide staining. (a) Extrusion of lamellar body lipids or sheets can be seen at the interface between the stratum granulosum (SG) and stratum corneum (SC). Scale bar 0.1 μm. (b) Sheets of lipid bilayers (arrowed) are present in the intercellular spaces of the SC. Some regions show a repetitive pattern of staining. D, desmosome. Scale bar 0.1 μm.

Figure 2.11

Structural organization of the keratin filament network within a keratinocyte.

Figure 2.12

There are three components to the hair cycle: anagen (where new hair forms and grows), followed by catagen (regressing phase) and telogen (resting phase), and then loss of old hair. The hair cycle is associated with discrete changes in hair follicle anatomy, both in the shape of the follicle and in the subjacent dermal papilla. IRS, inner root sheath; ORS, outer root sheath.

Merkel cell in human epidermis. The dermis (d) with collagen fibres is seen in the lower part of the picture; b, basement membrane; de, desmosomes making connections with adjacent basal keratinocyte; g, spherical granules (see inset); n, nucleus of Merkel cell; t, tonofilaments.

Figure 2.15

As part of the innate immune defence system, antimicrobial peptides can stimulate G-protein-coupled receptors to induce cytokine and chemokine release from keratinocytes as well as epidermal growth factor receptor (EGFR) signalling to influence cell proliferation and migration. CCL, chemokine (C–C motif) ligand; CXCL, C–X–C motif chemokine; IL, interleukin; MAPK, mitogen-activated protein kinase; STAT, signal transducer and activator of transcription.

Figure 2.16

The skin microbiome contains numerous bacteria that are variably present in different body regions. (Adapted from Chen and Tsao 2013 [3].)

Figure 2.17

Dendritic appearance of epidermal Langerhans cells. Exposure to antigen provokes an increased movement of Langerhans cells as well as direct cell–cell contact between Langerhans cells.

Figure 2.18

When exposed to foreign antigen, the activity of resting Langerhans cells increases and the cells mature. Antigen is then processed and transported to the lymph nodes. T cells are then activated and an immune response is triggered.

Figure 2.19

Langerhans cell (L) with its characteristically indented nucleus, situated between keratinocytes. The inset shows Langerhans cell granules with racquet-shaped profiles.

Figure 2.20

Immune surveillance in normal skin is carried out by an array of skin-based dendritic cells, macrophages and resident T cells. iNOS, inducible nitric oxide synthase; TNF, tumour necrosis factor.

Figure 2.21

Part of a human skin mast cell showing characteristic granules, some with scroll-like profiles (S). Arrows indicate perigranular membrane; L, lipid droplet; M, mitochondria; P, peripheral processes.

Figure 2.22

High-magnification views of dermal mast cell granules. (a) Typical scroll-like configuration of lamellae, some of which show a cross-banding of regular periodicity. (b) The substructure of this granule is a highly organized lattice (arrow).

Figure 2.23

(a) Activation of the melanocortin 1 receptor (MC1R) promotes the synthesis of eumelanin at the expense of phaeomelanin. Oxidation of tyrosine by tyrosinase (TYR), however, is required for synthesis of both pigment types. Melanosomal membrane components, including the membrane-associated transport protein (MATP) and the pink-eyed dilution protein (P), play a role in determining the amount of pigment synthesis within melanosomes. (b) In African, Asian and European skin there is a gradient of melanosome size and number; in addition, melanosomes in African skin are more widely dispersed.

Figure 2.24

Electron micrograph of desmosomes in the spinous layer. These intercellular junctions are closely associated with tonofilaments (tf), many of which, in this view, are cross-sectioned.

Figure 2.25

Macromolecular composition of desmosomes linking adjacent keratinocytes. Cells are connected via transmembranous cadherin glycoproteins (desmogleins and desmocollins). Attachment of these molecules to the keratin filament cytoskeleton occurs via a network of desmosomal plaque proteins (desmoplakin, plakoglobin and plakophilin). The background to this figure is a transmission electron micrograph of a desmosome to highlight how the molecules function as an adhesive complex.

Figure 2.26

Macromolecular composition of an adherens junction in keratinocytes. There are two main components, nectin–afadin and the classic cadherin–catenin complex, which can both attach to the actin cytoskeleton.

Figure 2.27

Formation and structure of gap junctions in human skin. (a) In the Golgi network six connexin subunits assemble to form a connexon. The connexon is then transported to the plasma membrane. Other connexons then co-aggregate to form homotypic or heterotypic gap junctions. (b) The gap junction protein is a transmembranous molecule with intracellular, transmembranous and extracellular domains (here illustrated for Cx26).

Figure 2.28

Structural composition of a tight junction in human skin. There are three transmembranous families of proteins, the junctional adhesion molecules (JAMs), the claudins and the occludins, of which the latter two bind to zonula occludens proteins (ZOs) and then directly to actin. MUPP1, multiple PDZ domain protein; MAGI, membrane-associated guanyl kinase inverted protein.

Figure 2.29

NaCl-induced separation between the epidermis and dermis and antigen mapping within the cutaneous basement membrane. (a) The dermal–epidermal basement membrane visualized by immunofluorescence staining with antibodies to type VII collagen. This maps to the base of the split because cleavage occurs through the lamina lucida, and type VII collagen is located below the lamina densa. (b) Molecular complexity at the dermal–epidermal junction and how various proteins map above or below the NaCl-induced split (red line and asterisk). BP, bullous pemphigoid.

Figure 2.30

Transmission electron microscopy of the dermal–epidermal junction in human skin recognizing hemidesmosomes (HD), anchoring filaments (Afl) and anchoring fibrils (Afb). The HD consists of an intracellular inner plaque (IP) and outer plaque (OP) as well as a sub-basal dense plate (SBDP) in the upper lamina lucida (LL). The anchoring filaments traverse the LL, appearing as thread-like structures that concentrate under the HDs and merge with the lamina densa (LD). Anchoring fibrils extend from the lower part of the LD to the upper papillary dermis where they closely associate with interstitial collagen fibres (Col). Keratin intermediate filaments (KIFs) associate with intracellular components of the HDs. Scale bar 0.25 μm.

Figure 2.31

Gene/protein systems within the cutaneous basement membrane zone that can harbour mutations and result in blistering of the skin in different forms of epidermolysis bullosa (EB). BP, bullous pemphigoid.

Figure 2.32

Immunofluorescence staining of the dermis and cutaneous basement membrane zone with an antibody for type IV collagen. Note positive staining at the dermal–epidermal basement membrane and around the dermal blood vessels. Original magnification 250×.

Figure 2.33

Demonstration of periodicity in collagen fibres of 640 Å. (a) Collagen fibrils in the reticular dermis show a characteristic banding pattern after standard processing and staining with uranyl acetate and lead citrate for transmission electron microscopy. Scale bar 0.1 μm. (b) Transmission electron micrograph of a shadowed replica of unfixed, freeze-frozen and surface-sublimated rat-tail tendon collagen showing the step-like banding of the fibres. Original magnification 40 500×.

Figure 2.34

Assembly of type IV and type VII collagen molecules into supramolecular structures. The red boxes represent intermolecular disulphide bonds.

Figure 2.35

Different isoforms and domain organizations of laminin, each consisting of three distinct subunit polypeptides, α-, β- and γ-chains. The LE modules are formed by approximately 60 residues each and have homology to epidermal growth factor. The LN and L4 modules are folded into globular structures located between the LE modules (domain IV) or at the amino-terminus of each chain (domain VI). The coiled-coil central region, comprising all three polypeptides, is represented as vertical straight lines. Note the presence of a G domain consisting of five globular segments (LG) at the carboxy-terminus of the α-chains. (Adapted from Aumailley and Rouselle 1999 [8].

Figure 2.40

Molecular interactions of the major components of the cutaneous basement membrane zone. The individual components are identified in the colour key and their domain organizations are given in Figure 2.39. BPAG, bullous pemphigoid antigen; HD, hemidesmosome. (Adapted from Pulkkinen and Uitto 1998 [7].

Figure 2.41

Transmission electron microscopy of the dermal–epidermal junction revealing wheatsheaf-shaped anchoring fibrils beneath the lamina densa. These fibrils help secure adhesion between the epidermal basement membrane and interstitial collagens within the dermis.

Figure 2.42

Transmission electron micrograph of a section of dermis from the human forearm showing bundles of collagen fibres, both in transverse and longitudinal sections. Original magnification 4900×.

Figure 2.43

Type XVII collagen, a transmembrane protein in type 2 orientation. Note that the ectodomain traversing the lamina lucida contains 15 distinct triple helical collagenous segments (COL1–15). The non-collagenous segment between COL15 and the transmembrane domain, NC-16A, harbours the major epitopes recognized by autoantibodies in bullous pemphigoid. ADAMTS, a disintegrin and metalloproteinase with thrombospondin motifs, cleaves the protein at a sequence in the NC-16A, resulting in release of the ectodomain. (Adapted from Powell

et al

. 2005 [12].)

Figure 2.44

Steps in the intracellular biosynthesis of triple helical type I procollagen, its secretion into the extracellular space, and assembly and cross-linking of mature collagen fibres in the extracellular space.

Figure 2.45

Enzymatic hydroxylation of prolyl residues in the Y-position of the repeating Gly-X-Y amino acid sequence to form hydroxyproline, an amino acid characteristic of collagen. Note that the reaction requires molecular oxygen, ferrous iron, α-ketoglutarate (α-KG) and ascorbic acid (As.Ac.) as co-factors.

Figure 2.46

Formation of intermolecular cross-links between individual collagen molecules. The cross-linking is initiated by the conversion of lysine or a hydroxylysine residue that contains an ε-amino group to a corresponding aldehyde (I). The aldehyde then reacts with an unmodified ε-amino group in an adjacent collagen molecule (II) to form a Schiff base-type covalent cross-link (III).

Figure 2.47

Structural organization of various matrix metalloproteinases (MMPs), divided into different subclasses. The signal, propeptide, active catalytic hinge and haemopexin regions are indicated. Note that MMP7 lacks the haemopexin region, while MMP14–17 harbour membrane-binding sequences at the carboxy-terminal end.

Figure 2.48

Main organization of various ADAMTS family metalloproteinases. The catalytic domain is shown in red, while other domains include the thrombospondin type I repeat sequences (green), disintegrin-like domain (blue) and cysteine domain (yellow). The signal peptidase is shown in black, the propeptide sequence is coloured pink and the spacer domain is in orange. ADAMTS, a disintegrin and metalloproteinase with thrombospondin motifs.

Figure 2.49

Immunofluorescence staining of type I collagen (a,d) and the elastic fibre network (b,e) in the dermis of human skin visualized by confocal laser scanning microscopy. Merging of the images (c,f) reveals that the elastic fibres assume a horizontal orientation in the mid-dermis while vertical extensions (oxytalan and elaunin fibres) reach the upper dermis, terminating just below the dermal–epidermal junction. Note that in sun-damaged skin there is a dramatic decrease and disorganization of both collagen and elastic fibres in comparison with sun-protected skin. (Adapted from Uitto and Bernstein 1998 [3].)

Figure 2.50

Transmission electron microscopy of an elastic fibre in the reticular dermis. The central electron-pale core consists of elastin (E), while the electron-dense areas represent the elastin-associated microfibrillar proteins which are particularly evident at the periphery of the fibre (arrow). Scale bar 0.5 μm.

Figure 2.51

Assembly and cross-linking of elastic fibres. Newly synthesized elastin precursor polypeptides, tropoelastins, with alternating hydrophobic and cross-link regions are secreted into the extracellular milieu. Lysine residues in characteristic lys-ala-ala-lys or lys-ala-ala-ala-lys sequences in the cross-link region undergo oxidative deamination of the ε-amino groups catalysed by lysyl oxidase, an enzyme requiring copper as a co-factor. Three resulting allysine residues fuse with an unmodified lysine residue to form desmosines, elastin-specific cross-link molecules. (Adapted from Mahoney

et al

. 2009 [7].)

Figure 2.52

Elastic fibres cross-linked by desmosines (red). In the relaxed state, the fibres assume coiled-coil conformations. When the fibres are stretched and then released, they return to a relaxed state, the contraction providing elasticity and resilience to the skin.

Figure 2.57

Transmission electron microscopy of an activated dermal fibroblast (F) in a healing wound. Note the prominent rough endoplasmic reticulum in the cytoplasm of this cell. There is an adjacent macrophage (M) with characteristic phagolysosomes, some of which contain ingested melanosomes.

Figure 2.58

Histology of microvessels in the reticular dermis. Arterioles (A) can be distinguished from venules (V) by the presence of elastic lamina, which stains red. Surrounding mast cells can be distinguished by their prominent red/blue cytoplasmic granules. Original magnification 400× (basic fuchsin and methylene blue stain).

Figure 2.59

Transmission electron microscopy of a cross-section through a small arteriole in the skin. Note the relatively smooth surface of the endothelial cell (E) surrounding the lumen (L) and the presence of smooth muscle (SM) with an associated nerve (N). There is a small amount of elastic tissue (el) adjacent to the endothelial basement membrane (bm).

Figure 2.60

Transmission electron microscopy of a transverse section through a venule in the skin. The surface of the endothelial cells (E) in the lumen (L) is more convoluted than in its arteriolar counterpart (see Figure 2.59). The endothelial cells are surrounded by pericytes (P), and not smooth muscle cells, and the basement membrane (bm) contains dense strands (small arrows). The arrowheads indicate Weibel–Palade bodies.

Epithelial stem cells are found within the interfollicular epidermis, the base of sebaceous glands and in the bulge area of hair follicles.

Figure 2.64

Epidermal stem cell proliferation is regulated positively by β1 integrin and transforming growth factor α (TGF-α) and negatively (–) by TGF-β signalling. The transcription factors c-Myc and p63 also promote epidermal proliferation. Notch signalling and the transcription factors peroxisome proliferator-activated receptor α (PPARα), AP2α/γ and C/EBPα/β control the differentiation of epidermal cells.

Figure 2.65

Possible mechanisms for the proliferative potential of stem cells (SC) in the basal keratinocyte layer. In the symmetrical division model, two stem cells are produced. Some of these cells in contact with the epidermal basement membrane are transient-amplifying cells (TA). These cells are capable of dividing four to five times before leaving the basal layer (delamination, black arrows) to become a spinous layer cell (SP) and entering terminal differentiation. In the asymmetrical division model, there is preferential partitioning of proliferation-associated factors into the stem cell daughter cell and, conversely, preferential partitioning of differentiation-inducing components into the daughter cell that is destined to become an SP. Depending on the orientation of the cell spindle, the daughter cell destined for differentiation can either become an SP directly or delaminate from the basal layer to enter terminal differentiation.

In vivo

, both mechanisms may exist.

Blocking of elliptical skin biopsy specimens. (a) Neoplastic lesions. Multiple transverse blocks through the whole lesion allow for histopathological examination of the tumour at all levels, and assessment of the narrowest excision margins. (b) Incisional biopsy of inflammatory lesion. Longitudinal blocking is recommended; this allows optimal visualization of the affected and adjacent normal skin.
