Trauma-induced dual-plane hemangioma in the hand: A case report

Hemangioma is a neoplastic disorder of vascular structures that can manifest at any site of the body. It is a rare ailment in general, and the intramuscular type is particularly uncommon and accounts for approximately 1 % of all hemangiomas. The presentation of hand hemangioma differs from other sites due to the restricted space and compression of vital structures, which frequently manifests as pain and functional impairment alongside mass. In this article, we present a case of trauma-induced dual-plane hemangioma in the hand.

A 55-year-old right-handed individual, without any significant medical background, sought medical attention for a painful mass on his right hand that had developed over the past year. He indicated a history of blunt trauma to the hand, with the mass becoming apparent two months post-injury. With the growth of the mass, the severity of pain progressively escalates; however, there is no loss of function observed. The diagnosis was established through duplex ultrasonography, and the patient received surgical excision utilizing the WALANT technique. Intraoperatively, the hemangioma was identified in two planes: one beneath the skin over the thenar eminence and another within the adductor pollicis muscle. The follow-up period proceeded without any complications or recurrence of the condition.

Hand hemangiomas are relatively rare, and a history of trauma may lead to misdiagnosis as other conditions. There are various management strategies that are not suitable for hand hemangiomas. While surgical excision can alleviate symptoms, it carries the risk of increasing disability if muscle tissue is excised.

Trauma-induced dual-plane hemangioma in the hand is a phenomenal condition that has been successfully treated surgically. Despite the removal of a portion of the adductor pollicis, both functional and aesthetic satisfaction was achieved. Hence, it is advisable to employ surgical management for such a presentation.
