Cylindroma

cylindroma

A benign skin adnexal tumour, seen on the face, trunk and extremities, which has apocrine differentiation. Cylindromas may be solitary (and sporadic or multiple) with an autosomal dominant hereditary pattern. Cylindromas are often associated with trichoepitheliomas, especially on the scalp (turban tumour), first develop in adolescence and rarely undergo malignant degeneration.

cyl·in·dro·ma

(sil'in-drō'mă)
Slow growing, infiltrative tumor frequently found in submaxillary and parotid salivary glands and accessory glands of the palate. Chief histologic feature is presence of uniform, small dark-staining basal cells in anastomosing cords, with acellular areas between.
