Plasmacytoma of the lung. A case report describing two tumors of different immunologic type in a single patient.

Two pulmonary plasmacytomas of different immunologic type, occurring with an interval of 5 years in the same 65-year-old woman are reported. Both displayed identical light chain types, but different heavy chains. The immunoperoxidase staining technique was used. The patient underwent segmental resection, and no evidence of recurrence or multiple myeloma was found 4 years later. Differential diagnoses are discussed, and the importance of immunologic staining is stressed.

Ultrasonic visualisation of the inflamed appendix.

A prospective ultrasonic study of the right lower abdominal quadrant was performed in 46 patients prior to appendicectomy. Ultrasonography revealed an inflamed appendix in 24 out of 29 patients with appendicitis and excluded its presence in 16 out of 17 patients without appendicitis. The ultrasonic pattern of the inflamed appendices appeared as echo-poor/echo-free lesions with lack of movement. In six of seven patients with perforated appendices, ultrasonography revealed free intra-abdominal fluid in addition to bowel disease. The possible value of abdominal ultrasound in patients with suspected acute appendicitis is discussed.
