title: Soft tissue amyloidoma of the extremities: a case report and review of the literature.
abstract: The deposition of amyloid as a distinct, clinically apparent mass is uncommon, particularly in soft tissues. Among reported sites of soft tissue amyloidomas, the extremities are quite rare. Amyloid tumors can mimic malignant neoplasms both clinically and radiologically. We report a case of AA amyloidoma presenting in the deltoid region with radiological features suggesting sarcoma. Cytomorphology from fine-needle aspiration material, tissue histology, and appearance by magnetic resonance imaging are described. The literature on soft tissue amyloidoma is reviewed.
