Abstract

Fibrous hamartoma of infancy is a rare soft tissue tumor in infants and young children with a characteristic triphasic morphology, typically occurring in the axilla and rarely in other locations. A 9 years old girl presented with complaints of swelling over right arm. On examination, a mobile and non-tender lump (size: 1.5~2 cm) was identified. Local excision was performed and tissue was sent for histopathological examination. The microscopic examination revealed fibrous hamartoma of infancy. Fibrous hamartoma of infancy is a rare benign entity with limited clinical features having an excellent prognosis, therefore a proper diagnosis is mandatory in treating it.
