Ureteral intussusception by papillary transitional cell carcinoma.

A case of ureteral intussusception caused by a low-grade papillary transitional cell carcinoma of the ureter is described. This is the first case of ureteral intussusception resulting from a malignant tumor of the ureter. The patient presented with weight loss and vague pain in the right lower abdominal quadrant. Right ureterovesical junction obstruction was seen in the retrograde pyeloureterogram. Right nephroureterectomy including a cuff of adjacent bladder wall was performed.

Mycotic aneurysms of the pulmonary arteries in intravenous drug addicts. Report of three cases and review of the literature.

During the postmortem study of pulmonary lesions in intravenous drug addicts, three patients were found to have bilateral multiple mycotic aneurysms of the peripheral pulmonary arteries in association with embolic pneumonia. Two of these patients had infective tricuspid endocarditis, and one had hemoptysis. This report draws attention to the occurrence of mycotic aneurysms in this unusual location and suggests that these pulmonary lesions may be more common than currently believed.

Carcinosarcoma of the lung with spindle-cell epithelial component: report of a case.

A case of primary endobronchial carcinosarcoma with predominant spindle cell squamous carcinoma is described. The spindle cell component has not been previously reported as occurring in pulmonary carcinosarcomas. We suggest that this variety of carcinosarcoma closely resembles sarcoma of the lung histologically and emphasize that a distinction between the two neoplasms is important in view of the generally good prognosis of endobronchial carcinosarcomas.

Perforated diverticulum of the terminal ileum. A previously unreported cause of suppurative pylephlebitis and multiple hepatic abscesses.

We describe the case of a 58-year-old man who presented to the hospital with central abdominal pain, nausea, fever, chills, and dyspnea. While in the hospital, jaundice appeared and the liver function tests revealed features of both cholestasis and hepatocellular injury. He developed gram-negative septicemia and died on the sixth hospital day. Autopsy disclosed a perforated terminal ileal diverticulum and a contiguous mesenteric abscess. There was also severe phlebitis of mesenteric venous radicles which extended superiorly to the intrahepatic portal venules and veins. The portal veins were surrounded by multiple hepatic abscesses that varied in size from microscopic to 2.5 cm. This appears to be the first report in the world literature of suppurative pylephlebitis and hepatic abscesses resulting from a perforated ileal diverticulum. The subject of small bowel non-Meckelian diverticulosis is reviewed because of the rarity of this condition and the diagnostic challenges it poses.

Granular cell tumor of the bronchus: a previously unreported cause of hypercalcemia.

Hypercalcemia was found in a patient with an endobronchial granular cell tumor. To the best of our knowledge, the association of hypercalcemia and granular cell tumor has not been previously reported in the literature. Resection of the tumor resulted in the return of the serum calcium levels to normal. Investigation of the metabolic status of the patient suggested that the tumor was not producing parathormone.
