Histopathologic exarnination revealed sebaceous gland, eccrine gland and crosssectioned hair in the surrounding tissue, hair shaft projected into the lumen, and laminated horny material in the cyst. Transitional zone between stratified squarnous epithelium and the wall lined by histiocytes showed homogenous degenerative change. After surgical removal of the lesion, no recurrence was observed during 15 months of follow-up.
