title: Intestinal pseudotumorous gouty nodulosis: a colonic tophus without manifestation of gouty arthritis.
abstract: A 37-year-old black woman with nephritis secondary to systemic lupus erythematosus, steroid-induced diabetes mellitus, and hypertension presented with fever, nausea, vomiting, and right upper quadrant abdominal pain with distension. Abdominal computed tomography (CT) scan revealed a colonic mass, and CT- guided fine-needle aspiration demonstrated birefringent crystalline material. After several weeks of antibiotic therapy, the patient underwent laparoscopic examination followed by extended right hemicolectomy for a large mass in the subserosa of the transverse colon. Pathological examination of this mass revealed it to be a gouty tophus. To our knowledge, no case of tophaceous gout presenting as an intestinal mass has previously been reported.
