Angiodysplasia of the appendix.

Angiodysplasia of the gastrointestinal tract is thought to be one of the most common causes of lower gastrointestinal bleeding in the elderly, and, in the majority of cases, lesions are located in the cecum or ascending colon. The authors report an extremely rare case of appendicular angiodysplasia. A 76-yr-old woman was hospitalized with massive recurrent red anal bleeding. Selective superior mesenteric arteriography revealed an extravasation of contrast material from the appendicular artery, and this finding proved to be bleeding from an angiodysplasia of the appendix. An appendectomy was performed, and anal bleeding did not recur postoperatively. A review of the literature revealed this to be an extremely rare case of angiodysplasia.

Long-Term Survival After Resection of Metachronous Bilateral Adrenal Metastases of Mucinous Gastric Carcinoma: Report of a Case

We report a case of metachronous bilateral adrenal metastases from mucinous adenocarcinoma of the stomach. A 68-year-old man who had undergone surgery for advanced gastric cancer 5 months earlier had a follow-up computed tomography (CT) scan, which showed a right adrenal tumor. We performed a right adrenalectomy, and histopathological examination revealed a mucinous adenocarcinoma with features consistent with those of gastric cancer. A routine follow-up CT scan done 41 months after the right adrenalectomy showed a left adrenal mass. Chemotherapy had no apparent effect, and left adrenalectomy was performed 65 months after the right adrenalectomy. Histopathological examination also revealed a metastasis from gastric cancer. The patient was alive without recurrence 40 months after the left adrenalectomy. This case suggests that resection of adrenal metastasis from gastric cancer is an effective treatment option that may prolong survival in selected patients.
