CHAPTER 72
Skin lesions associated with gastrointestinal and liver diseases and oral manifestations of gastrointestinal diseases

Many diseases of the gastrointestinal tract have characteristic dermatological manifestations. Such manifestations may develop before, concomitantly with, or after the onset of gastrointestinal diseases. Recognition of the cutaneous manifestations of gastrointestinal diseases may be significant for diagnosis and management purposes. In addition, primary skin diseases may affect the gastrointestinal tract, display characteristic alterations, and/or produce specific complications.


In this chapter, the cutaneous manifestations of diseases with the following overall characteristics are illustrated.



  • Inherited disorders with an increased risk of gastrointestinal malignancy (Figures 72.172.6).
  • Genodermatoses (i.e., inherited skin disorders) with characteristic gastrointestinal manifestations (Figures 72.772.15).
  • Paraneoplastic and related syndromes with gastrointestinal and cutaneous manifestations (Figures 72.1672.22).
  • The cutaneous manifestations of inflammatory bowel disease (Figures 72.2372.37).
  • Immunologically mediated diseases with gastrointestinal manifestations (Figures 72.3872.58).
  • The cutaneous manifestations of liver disease (Figures 72.5972.81).
  • The mucocutaneous manifestations of nutritional deficiencies (Figures 72.8272.85).
  • Miscellaneous disorders associated with cutaneous and gastrointestinal manifestations (Figures 72.8672.90).

Figure 72.2 Keratoacanthoma. In Muir–Torre syndrome, sebaceous tumors and keratoacanthomas occur in association with internal malignancies (e.g., colonic adenocarcinomas, neoplasms of the genitourinary tract).

Figure 72.4 Epidermal inclusion cyst. In Gardner syndrome, epidermal inclusion cysts, pilomatricomas, lipomas, fibromas, and desmoid tumors are seen in association with colonic adenocarcinomas.

Photo depicts multiple epidermal inclusion cysts.

Figure 72.5 Multiple epidermal inclusion cysts. While epidermal inclusion cysts are common sporadic neoplasms of the skin, patients with Gardner syndrome develop numerous cysts in a widespread distribution.

Photo depicts lipomas.

Figure 72.6 Lipomas. While lipomas are common sporadic neoplasms of the skin and subcutis, patients with Gardner syndrome develop numerous lipomas.

Photo depicts pseudoxanthoma elasticum (PXE).

Figure 72.7 Pseudoxanthoma elasticum (PXE). PXE is an inherited connective tissue disease characterized by abnormalities in elastin fibers. Skin lesions dominate in flexural areas and display a cobblestone appearance. Vascular involvement commonly results in hemorrhage (e.g., gastric hemorrhage).

Photo depicts hereditary hemorrhagic telangiectasia is characterized by diffuse mucocutaneous telangiectases and visceral arteriovenous malformations.

Photo depicts neurofibromatosis type 1 (NF1, von Recklinghausen disease).

Figure 72.9 Neurofibromatosis type 1 (NF1, von Recklinghausen disease). Cutaneous manifestations of NF1 include café‐au‐lait macules, axillary or inguinal freckling, and neurofibromas.

Photo depicts acanthosis nigricans (AN) is characterized by hyperpigmented velvety lesions that typically affect skin on the neck, axillae, groin, or other sites.

Figure 72.16 Acanthosis nigricans (AN) is characterized by hyperpigmented velvety lesions that typically affect skin on the neck, axillae, groin, or other sites. In rare instances, AN signifies a paraneoplastic phenomenon.

Photo depicts seborrheic keratoses (SKs) are benign skin neoplasms that are quite common and usually multiple.

Figure 72.18 Seborrheic keratoses (SKs) are benign skin neoplasms that are quite common and usually multiple. The sign of Leser–Trelat, a rare cutaneous manifestation of internal malignancy (e.g., gastric adenocarcinomas, colon adenocarcinomas, breast carcinoma, lymphoma), represents an abrupt and striking increase in the number and/or size of SKs.
