Abstract:
Steatocystoma simplex is a rare benign cutaneous cyst that is thought to be a circumscribed malformation arising from the pilosebaceous duct junction. Reports describing steatocystoma simplex are scarce and many issues remain to be clarified, including frequency and age distribution. Steatocystoma simplex is generally considered to be a solitary, non-inherited tumor arising in adults; there have been no previous reports of steatocystoma simplex in infants. We encountered two cases of steatocystoma simplex arising on the head in infants less than 2 years old. Herein we discuss the clinical and pathological characteristics of these cases.
