Abstract
- Trichodiscoma are hamartomas of the dermal portion of the hair disc, and these are found as asymptomatic flesh- colored papules 1~3 mm in diameter, and they are usually located on the face, trunk and thigh. Histopathologically, this is characterized by non-encapsulated fibrovascular lesion with a myxoid stroma surrounded by folliculo- sebaceous units. Birt-Hogg-Dube syndrome, which develops multiple trichodiscomas with fibrofolliculomas and skin tags, has been described. The case of solitary trichodischoma is rare. We recently encountered a 29-year-old woman with a solitary, dome-shaped papule on the right thigh. After histopathologic examination, the lesion was diagnosed as trichodiscoma.
