- Abstract: Trichoadenoma is a rare benign tumor and it appears as a solitary tumor on the face and buttock. Histologically, it is characterized by numerous horny cysts lined with stratified squamous epithelium and solid epithelial tumor nests. This tumor is less mature than trichofolliculoma and more differentiated than trichoepithelioma, and it is considered as a tumor with differentiation toward the infundibular portion of the pilosebaceous canal. A 39-year-old woman presented with asymptomatic, solitary, 1.5x1.5 cm sized, pedunculated mass on her buttock for 2 years. Histopathologic examination showed characteristic features of trichoadenoma. Trichoadenoma is so rare that only 3 cases have been reported in the Korean literature.
