Two Cases of Trichilemmoma
Abstract
- Trichilemmoma is a benign neoplasm originated from the outer root sheath of hair follicle and usually occurs as small solitary papule on the face, particulary on the nose and cheek. Most lesions are clinically misinterpreted as basal cell carcinoma or verruca vulgaris. We report two cases of trichilernmoma on the face which were misdiagnosed as verruca vulgaris clinically. The histopathologic findings revealed lobular acanthosis of glycogen rich clear cells oriented about a follicle. At the edge of the lesions, a, palisade of columnar cells, which resembled the outer root sheath of hair follicle, rested on a thickened basement membrane. The skin lesions were removed by 3mm punch without recurrence.
