Abstract:
Fibrofolliculoma is a benign perifollicular connective tissue tumor that usually occurs in the face. Most fibrofolliculoma present as multiple lesions and typically occur with trichodiscomas and acrochordons, constituting the Birt-Hogg-Dube syndrome. Solitary fibrofolliculoma is nonhereditary and unassociated with other cutaneous abnormalities. A 72-year-old man visited our clinic complaining of a solitary umbilicated nodule on the antitragus of the left ear. Skin biopsy from the lesion showed a central dilated follicular infundibulum with anastomosing bands of follicular epithelium extending into the fibrous stroma. The diagnosis of a solitary fibrofolliculoma was made based on the clinical and histopathological findings. No signs of lesion recurrence for 1 year after shave removal were noted. We report a rare case of solitary fibrofolliculoma that occurred on the antitragus of the ear.
