ABSTRACT
Approximately 10% of pheochromocytomas are malignant and its major criteria are tumor invasion of capsular blood vessel as well as metastatic invasion of other tissues. It is general rule that all resectable masses have to be removed surgically. However, there is no definite treatment modality about unresectable masses or microinvasive lesions. We experienced a case of 45 year-old male patient who was referred to our hospital for treatment of hypertension and headache. The plasma and urine catecholamine were increased above normal values and its metabolites also were increased. 131I-metaiodobenzylguanidine (MIBG) scan showed right adrenal mass and metastatic lesion of left iliac bone. This lesion was consistent with findings of the abdomen computed tomography (CT) and electron beam tomography (EBT) scan. We diagnosed this case as malignant pheochromocytoma. We removed primary tumor mass by wide excision and treated this patient with high dose 131I-MIBG. We report this case who shows good response to the high dose 131I-MIBG after surgery.

Double primary cancer means that more than two cancers with different origin exist independently in an individual. The diagnosis of double primary cancer was determined by following criteria. Each of the tumors must present a definite picture of malignancy, and each must be distinct, and the probability of one being a metastasis of the other must be excluded. Small cell carcinoma has a distinct biological behavior such as, early invasion and metastasis, a rapid clinical course, and significant sensitivity to chemotherapy. Small cell carcinoma in the esophagus is relatively rare, and rarer when it is combined with other malignant disease. We have experienced a case of double primary cancer, a 70-year-old man with esophageal small cell carcinoma and gastric adenocarcinoma, which were diagnosed by gastrointestinal endoscopic biopsy. A review of the Korean medical literature failed to reveal any previously described case of esophageal small cell carcinoma with gastric adenocareinoma. We report this case with review of literatures.

Intestinal tuberculosis has been known since antiquity. After about 1950's, effective antituberculous chemotherapy and an improved standard of living resulted in a steady decline in all forms of tuberculosis. However, intestinal tuberculosis has been reported with impressive frequency in developing countries including Korea. Disease affecting the duodenum is reported to be rare and isolated duodenal tuberculosis sparing the rest of the intestine is uncommon. We experienced a case of tuberculosis of duodenal bulb associated pulmonary tuberculosis. The diagnosis was made on the basis of the histological study of the endoscopic biopsy specimen. We have confirmed the healing of the duodenal lesion by the follow-up endoscopy after 9 months treatment of antituberculous medication.
