Abstract
-
Tumor of the follicular infundibulum(TFI) is a rare benign adnexal tumor originating from the infundibular portion of hair follicle. Majority of the lesions have been solitary and not recognized clinically before biopsy. TFI can be classified as follows according to the clinical presentation of the tumor (1) solitary tumor, (2) eruptive tumors, (3) TFI associated with other lesions of Cowden's disease, (4) TFI arising in nevus sebaceus, and (5) TFI-like changes in various tumors. We present clinicopathologic features of 2 cases of TFI. One was a solitary form and the other was associated with nevus sebaceus.
