Hamartoma is a nonneoplastic proliferation of mature cells and tissues indigenous to the affected part. They are classified as lipomatous, neurogenic, vascular, angiomatous, etc., based on the predominance of tissue in them. This is a case of vascular hamartoma of the infrascapular region in a young male. He was evaluated elsewhere with magnetic resonance imaging and incisional biopsy and referred to our institute for further management. After initial contrast-enhanced computed tomography of the thorax, the mass was excised surgically with adequate margins and the wound was closed primarily. The final biopsy report of the mass showed a vascular hamartomatous lesion. Hence, hamartoma should be considered one of the differentials for a soft-tissue mass found anywhere in the body and proper preoperative imaging and planning of appropriate intervention is necessary.
