Primary aortic tumors are rare, difficult to diagnose, and often fatal. This case and a review of the literature identified aortic tumors as a potential source of emboli leading to acute mesenteric insufficiency. The case showed the efficacy of magnetic resonance imaging in diagnosing and determining the extent and location of an aortic tumor.

In a 45 year old man, hepatic angiosarcoma developed 33 years after medicinal arsenic ingestion of only six months' duration. In addition, the patient had a history of basal cell carcinomas without having had excessive sunlight exposure. Factor VIII staining of the tumor supports an endothelial cell origin of the tumor. The development of skin cancers and hepatic angiosarcoma in this patient suggests that there may be no safe threshold of arsenic exposure. A careful history concerning even short-term arsenic exposure in all patients with hepatic angiosarcoma may uncover more examples of this association.
A case of Candida costochondritis seen initially as a chest wall tumor in a narcotic addict is reported. Bone and cartilage are rare sites of Candida infection from whatever cause. Since 1973, only 6 cases of Candida costochondritis have been reported; 5 were complications of thoracic operations and the other, of intravenous hyperalimentation. Treatment by a one-stage en bloc resection of chest wall, and reconstruction by rib graft and Marlex mesh resulted in cure in our patient, without complications.
Multilocular renal cysts may occur bilaterally. A partial nephrectomy usually is curative but unroofing of the cyst may lead to recurrence. We suggest to delete the criterion of unilaterality and to base the diagnosis on histological features. The first case of bilateral multilocular renal cysts with unilateral recurrence is reported.
