FRACS Orthopaedic Exams
A fifty-six-year-old woman presented with a ten-year history of a soft-tissue mass in the left shoulder. The mass had increased in size over the prior eighteen months. The mass was moderately painful with activities such as heavy lifting or carrying. The patient had no night pain, nor did she have a history of trauma to the area, erythema, bruising, fevers, chills, night sweats, or weight loss.
On plain radiography, there was no evidence of osseous involvement or soft-tissue calcifications. A computed tomography scan with contrast was performed.
An open biopsy was performed, and a specimen was sent for histologic analysis.
