Steatocystoma simplex

Solitary steatocystoma (simple sebaceous duct cyst, steatocystoma simplex) occurs with equal frequency in adult women and men, and can be sited on the face, trunk, or extremities. The oral mucosa may also be involved. It is not familial, and solitary lesions are much less common than multiple ones. The cysts are usually 0.5–1.5 cm in size, although rarely solitary steatocystomas over 8 cm have been reported. The cyst contains an oily, yellow fluid and may contain vellus hairs. Histologically, the cyst is lined by stratified squamous epithelium. Small, mature, sebaceous lobules are present along the cyst wall and empty into the cyst. The luminal surface of the cyst is eosinophilic, wavy (shark tooth pattern), and ribbon-like, analogous to the sebaceous duct. “Hydrid” cysts may have portions of their lining of the steatocystoma type, with the other portions resembling pilar cyst, epidermoid cyst, or even pilomatricoma. Simple excision is curative.
