Unusual abdominal location of a dermal cylindroma.

Cylindromas are rare benign adenexal tumors that classically arise on the head and neck, thus earning the name of turban tumor. They are usually benign, but may be multiple and recurrent. A 78-year-old woman noted an abdominal cylindroma, an unusual presentation of this rare cutaneous tumor. The clinical presentation, histologic characteristics, and variations of the dermal cylindroma are reviewed.
