Benign adnexal tumor with differentiation of sebaceous glands.

Located mainly on the face, capillitium and neck, less frequently on the upper trunk. Rarely also occurring in the area of the oral mucosa.

Clinical features
This section has been translated automatically.

Mostly solitary, soft, easily distinguishable, skin-coloured or slightly yellowish papules/nodes of 0.5 (maximum) 2.0 cm diameter. The clinical findings are otherwise uncharacteristic. Only the slightly yellowish colour may indicate sebaceous differentiation. In this respect the diagnosis is made histologically.

Notice! Multiple sebaceous gland adenomas in combination with carcinomas of the internal organs are suspected of Muir-Torre syndrome.

This section has been translated automatically.

Well defined, lobar adenoma in the upper and middle dermis with recognizable differentiation of sebocytes. In addition to sebocytes there are basaloid, basophilic seboblastic cells. The seboblasts condense at the periphery of the lobules to form a multilayer strip. There is extensive contact with the surface epithelium.
