en تومور Tumor surgery گزارش مورد Case Report <strong>Background</strong>: Glomus tumors (GTs) are infrequent, benign soft tissue neoplasms originating from the thermoregulatory apparatus of the glomus body. Predominantly, these tumors manifest in the hand. Although uncommon, the occurrence of GTs in extra digital locations and their intravenous presentation is a seldom observed phenomenon, posing a diagnostic challenge.<br> <strong>Case Presentation</strong>: In this case study, we document the presence of an intravenous GT in the elbow region, which manifested as chronic elbow pain with an atypical presentation characterized by the ineffectiveness of various treatments.<br> <strong>Conclusion</strong>: Following surgical intervention and excision of the tumor, the patient experienced complete resolution of symptoms. Hence, despite the rare incidence of this tumor, it warrants consideration in cases of persistent and refractory pain.
