A Case of Fibrous Hamartoma of Infancy with Overlying Hypertrichosis / 대한피부과학회지

ABSTRACT

Fibrous hamartoma of infancy is an uncommon benign soft tissue tumor, characterized by three different tissue components histologically; 1)intersecting trabeculae of fibrous tissue, 2)immature cells with mucoid matrix, and 3)mature fat. The majority of fibrous hamartoma of infancy occur within the first year of life as a painless nodule and a few cases have overlying skin changes, including alteration in pigmentaion, eccrine gland hyperplasia and increased hair. We report a case of fibrous hamartoma of infancy on the buttock with overlying hypertrichosis in an 8-month-old male patient.
