The paper presents information regarding a rare skin disease Gottrons carcinoid papillomatosis, for the first time described in 1932 by German dermatologist H.A. Gottron. Its development is associated with the preceding chronic dermatoses and disturbance of circulation in the lower extremities. Morphologically, Gottrons carcinoid papillomatosis of the skin is characterized by the development of pseudoepitheliomatous hyperplasia of epidermis. Clinical picture, dermatoscopy, ultrasound and histological studied were used for diagnosis. This disease should be differed from high differentiated squamous cell carcinoma of the skin, chronic ulcerous pyodermavegetans, lupus verrucosis, chromomycosis. We described our own clinical observation of Gottrons carcinoid papillomatosis of the skin, developed against a background of psoriasis.
