A Case Report: Fibrous Hamartoma of Infancy in the Buttock

ABSTRACT

Fibrous hamartoma of infancy is an uncommon, benign, subcutaneous fibrous proliferation and usually found during the first 2 years of life, presenting non- tender, hard and movable soft-tissue mass. This tumor can cause much concern about malignancy because it may be fixed in the underlying tissue and is composed of poorly differentiated mesenchymal cells. The diagnosis is made easily by the characteristic histologic features, treatment is local excision and the prognosis is excellent. Because misdiagnosis of malignancy can lead to unnecessary radical therapy, both surgeon and pathologist must be aware of this entity. We experienced and report a case of a 11 month-old male patient who had a 10x15 cm sized hard, fixed and non-tender mass on the right buttock that manifested characteristic pathology of this disease. We excised the mass widely with safety margin of 1 cm and no recurrence was reported in 12 months.
