Abstract
- Very rare and unique tumors of infants, fibrous hamartomas were first described by Reye in 1956 as a subdermal fibromatous tumor of infancy. The tumors can occur at birth and are usually diagnosed within the first 2 years of life. The oldest patient reported in the literature was an 11-year-old child. The common sites of involvement are the axillae, upper arms, and upper trunk. Although the lesion is not distinctive clinically, it has a characteristic microscopic appearance of fibrous tissue forming trabeculae, small, round cells that represent primitive mesenchyme, and mature adipose tissue. Herein, we report a case of fibrous hamartoma of infancy in a 26-year-old man, on the uncommon site of a lower extremity.
