Abstract
- Fibrous hamartoma of infancy (FHI) is an uncommon benign fibrous proliferation, usually presenting as a single nodule. A 17-month-old male patient had an asymptomatic fingertip-sized subcutaneous nodule on the right side of the back for 6 month. Histopathologic findings showed the typical feature of FHI, that is well defined intersecting fibrous trabeculae, small immature cells within loosely textured areas, and mature adipose areas in the lower dermis and subcutaneous layer. Immunohistochemically, vimentin positivity was present in both the trabecular and loosely textured areas, but desmin was not present in any components which is positive usually only in trabecular areas. The lesion was excised without recurrence. We experienced and report an uncommon case of fibrous hamartoma of infancy in a 17-month-old male patient.
