The clinical picture of perifollicular benign tumors resemble that of juvenile warts, but the histopathology is completely different. Three different forms of perifollicular tumors, pure or mixed, have been observed. We report a fourth, previously unrecorded form, named perivascular fibroma from its histological appearance. The histological findings indicate a possible inflammatory etiology, as is also suggested by perifollicular fibroma, whereas postinflammatory signs are absent in trichodiscoma and fibrofolliculoma. The prognosis after removal of these tumors is favorable.
