Tufted Angioma of the Index Finger Middle Phalanx.

A tufted angioma is a benign vascular tumor of the skin and subcutaneous tissue that classically presents as a violaceous nodule on the trunk or extremities in early childhood. Tufted angiomas of the finger are uncommon, and intraosseous involvement of these tumors is exceedingly rare. When present in the bone, these lesions may be difficult to distinguish from the more common pediatric condition of osteomyelitis or osteoid osteoma. We present the clinical, radiographic, and histopathologic findings for a unique case of a tufted angioma with intraosseous involvement in the middle phalanx treated by surgical excision and curettage with preservation of function.
