Lymphomatoid granulomatosis is a non-neoplastic lymphoreticular disorder that usually presents as primary lung disease. A case of lymphomatoid granulomatosis associated with retroperitoneal fibrosis is reported. The retroperitoneal fibrous tissue contained the same variegated lymphoreticular infiltrate that formed the lung tumor, suggesting that the disease may have begun in the retroperitoneum. An extensive immunologic evaluation of the patient revealed impaired cell-mediated immunity.

Direct selective observation of the intravascular lumen through a catheter cardioangioscope provides accurate diagnostic information that facilitates the detection and treatment of vascular diseases. The Sumida-cardioangioscope is approximately 0.75 to 2.4 mm in diameter and consists of at least 3,000-6,000 delicate glass fibers, each measuring 4.8-5.5 micron and fused into a long flexible 75 to 130 cm tube. The cardioangioscope has the following components: (1) a scope connected to a camera; (2) a lightguide, consisting of 80-500 fibers, measuring 30-50 micron in diameter, and a 75-watt xenon lamp; (3) a transport channel for saline or drug solution; (4) an inflatable cuff; and (5) a handle to manipulate the catheter tip. The abdominal aorta in living dogs and the coronary arteries, aortic valves, abdominal-iliac, femoral and popliteal arteries, abdomino-iliac bifurcation, and venous system were clearly observed and recorded on videotape, 16-mm movie film and 35-mm photographic film. Angioplasty by balloon and laser ablation are possible applications.
