RESUMO
Fibrous hamartoma of infancy is an uncommon fibroproliferative lesion that occurs only in infancy and childhood. It predominantly affects healthy boys and can be found in almost any subcutaneous tissue. The tumor is most frequently found in the axilla, followed by shoulder, inguinal area, and chest wall. This tumor can cause much concern about malignancy because it is firm and may be fixed to underlying tissues. Despite the occasional local recurrence, the clinical course is benign and the prognosis is excellent. Treatment is by local excision. The diagnosis is made by the characteristic histologic features. In order to avoid the misdiagnosis of malignancy and unnecessary radical therapy, both surgeon and pathologist must be familiar with this entity. We report a case of fibrous hamartoma of infancy in a 4-year-old boy in gluteal region
