Abstract

Tumor of follicular infundibulum (TFI) is a rare benign cutaneous appendage tumor that does not have characteristic clinical features. It is mainly present in the head, neck, and trunk as a solitary lesion. In particular, TFI typically manifests as a plate-like proliferation with multiple thin epidermal connections comprise of monomorphic cells. TFI do not represent cutaneous characteristics, but have clinical significance because TFI is associated with basal cell carcinoma and Cowden's syndrome. We report a case of TFI in parietal scalp with a review of literatures.
