Supraclavicular glomus tumor, 20 year history of undiagnosed shoulder pain: a case report.
A long-standing case of severe dysesthesia due to a supraclavicular glomus tumor is presented. Chronic pain caused by a subcutaneous glomus (non-chemodectoma) tumor is rare and usually misdiagnosed. The supraclavicular location, presentation, and coincidence of trauma history are unique in this case. A 62-year-old male complained of 20 years of intractable right shoulder and supraclavicular region pain, which started 6 months after a fall. The pain was unrelieved by repeated and extensive physical therapy, chiropractic manipulation, local steroid injections, and two shoulder operations. The cause of the condition remained undiagnosed and obscure. Local surgical exploration revealed a subcutaneous grayish mass with pathologically proven glomus tumor. Immediate alleviation of the pain and tenderness followed complete resection of the mass. The patient remained free of pain at a 2-year follow-up. Subcutaneous glomus (non-chemodectoma) tumors can occur in unusual sites, and should be considered in chronic regional pain syndromes. Immediate cure is generally achieved by local resection. Pertinent literature is reviewed.
