Glomus tumor located in deltoid muscle

Glomus tumors are benign soft tissue neoplasms arising from the glomus body, which are primarily found under the nail bed of the fingers. They are rarely located in other parts of the body. Only 8 cases of glomus tumors around the shoulder have been published in the literature. The purpose of this study was to present a glomus tumor located in the deltoid muscle in a 68-year-old male patient that was surgically treated by marginal excision. The patient remained asymptomatic, and no recurrence was detected at 2-year follow up.
