Multiple myeloma with extramedullary plasmacytoma is unusual, but associated gastrointestinal involvement is even rarer. A case with initial presentation as solitary plasmacytoma of the clavicle and subsequent lesions in the maxillary sinus, skin, and ascending colon is reviewed. The variable radiographic features of plasmacytoma of the colon are discussed, whether occurring as a solitary finding or in a patient with multiple myeloma.
A case of mucoid adenocarcinoma of the urachus demonstrated by ultrasonography, cystography, and computerized tomography is presented. The inhomogeneous, echogenic mass was confluent with the anterior--superior aspect of the bladder but was also associated with a fistula between the bladder and small intestine, a finding not previously reported.
