OBJECTIVE: To present a case of fibrous hamartoma in a late-dried infant presenting as an extensive injury, involving vascular and neural elements of brachial plexus. METHODS: Clinical case study and pertinent literature review. RESULTS: Male child, with right axillary irregular tumoral mass, of which onset occurred at 2 months of age and related to BCG vaccine application, being treated with anti-tuberculosis agents, not responding to therapy. Upon biopsy, the injury was diagnosed as children’s fibrous hamartoma, and, after a fast growing period, was submitted to total surgical exeresis. CONCLUSION: The juvenile fibrous hamartoma is a rare benign tumor, typically occurring within the first year of life in boys, most commonly located at axillary gap. The differential diagnosis is performed with soft parts tumors in general, and, in right axillary location cases, with axillary adenopathies caused by responses to BCG vaccine. Treatment approach is total exeresis of the injury and the prognosis is favorable.
