We retrospectively reviewed the chart of a patient with recurrent fibrous hamartoma of infancy (FHI). This lesion presented as a gradually enlarging mass on the child's buttock. The child, a 6-month-old male, was followed up, and at 19 months of age the mass was excised. Eighteen months after the initial operation, a local recurrence was noticed. Forty-one months after the initial operation, reexcision was performed. Both masses demonstrated the characteristic features of FHI, which should be considered in the differential diagnosis of subcutaneous mass in young children.
"A recommendation for a 1.0-cm surgical margin and excision in depth to include the adjacent normal tissue plane has been proposed . Local recurrences have been reported in up to 16% of cases due to an inadequate primary excision   . A secondary wider local excision was sufficient  . "
[Show abstract][Hide abstract] ABSTRACT: Fibrous hamartoma of infancy is a rare benign soft tissue tumor that usually occurs within the first 2 years of life. We report 3 cases of fibrous hamartoma of infancy seen over a 10-year period. Treatment is curative by local excision with a low local recurrence rate. Fibrous hamartoma of infancy should be considered in the differential diagnosis of soft tissue masses in children because it is always benign and subject to nonaggressive treatment.

[Show abstract][Hide abstract] ABSTRACT: Objective: Fibrous hamartoma of infancy (FHI) is a rare, benign soft tissue tumor that typically occurs within the first two years of life. It has a specific histologic appearance comprising of three different mesenchymal tissues with variable proportions in an organoid fashion. The clinical course is typically benign with excellent prognosis. We report two cases of this rare lesion and review its cilinicopathologic characteristics.Case(s) Presentation: The first case was a 15-month-old girl who had a subcutaneous mass in the right axillary region and the other one was an 18-month-old boy with a mass on the medial surface of his right ankle. The masses were successfully excised. After 6 and 30 months follow up no recurrence occurred.Conclusion: Although the clinical and imaging findings of FHI are quite similar to those of malignant soft tissue tumor, histologic characteristics of this tumor will guide to the definite diagnosis that will prevent aggressive and mutilating procedures.
[Show abstract][Hide abstract] ABSTRACT: Fibrous hamartomas of infancy (FHIs) are benign, poorly-circumscribed, soft tissue growths presenting during the first 2 years of life and characteristically affecting the axilla, upper arm, upper trunk, inguinal region, and external genital area. Involvement of the hands and feet is extremely rare. We report a case of FHI unusually occurring in a deep portion of the hand. MRI revealed atypical features similar to that of a vascular malformation, hemangioma, fibromatosis, or neurofibromatosis of the hand. Partial resection of the mass was performed to correct the contracture of the second finger and an additional operation was not performed because of the benign nature of FHIs.
