Atlas of Skin Manifestations of Internal Disease

In the practice of medicine, virtually every clinician encounters patients with skin disease. Physicians of all specialties face the daily task of determining the nature and clinical implication of dermatologic disease. In patients with skin eruptions and rashes, the physician must confront the question of whether the cutaneous process is confined to the skin, representing a pure dermatologic event, or whether it is a manifestation of internal disease relating to the patient’s overall medical condition. Evaluation and accurate diagnosis of skin lesions are also critical given the marked rise in both melanoma and nonmelanoma skin cancer. Dermatologic conditions can be classified and categorized in many different ways, and in this Atlas, a selected group of inflammatory skin eruptions and neoplastic conditions are grouped in the following manner: (A) common skin diseases and lesions, (B) nonmelanoma skin cancer, (C) melanoma and pigmented lesions, (D) infectious disease and the skin, (E) immunologically mediated skin disease, and (F) skin manifestations of internal disease.
