Granular Cell Tumor Adherent to the Clavicle: A Case Report

Robert C Weinschenk et al. JBJS Case Connect. .

Abstract

Case: A 57-year-old woman presented with a 1-year history of left shoulder pain with an atraumatic mass overlying the left clavicle. Magnetic resonance imaging showed an enhancing, spiculated mass adherent to the clavicle. Preoperative needle biopsy confirmed the diagnosis of granular cell tumor (GrCT). The patient underwent mass resection and was symptom free without evidence of recurrence during her most recent evaluation, 29 months postoperatively.

Conclusion: To the author's knowledge, this is the first case in the English literature of a benign GrCT with periosteal involvement. GrCT should be considered in the differential diagnosis of enhancing lesions abutting bone.

Keywords: clavicle; extremities; granular cell tumor; soft tissue mass.
