Solid cystic tumor of the pancreas in elderly men: report of a case.

Solid cystic tumor of the pancreas is a primary pancreatic neoplasm of unknown etiology that most commonly occurs in young women and ordinarily contains hemorrhagic tissue. We report herein the unusual case of a 75-year-old man found to have a solid cystic tumor in the body and tail of the pancreas, who is the oldest such male patient to be documented in Japan. The results of laboratory data and imaging studies indicated that the patient had a nonfunctioning islet tumor or solid cystic tumor of the pancreas, and distal pancreatectomy with splenectomy was performed. The diagnosis of solid cystic tumor was confirmed based on macroscopic and histological findings of the resected pancreatic tumor. The patient is currently in good health, without any signs of tumor recurrence 1 year and 4 months after his operation. A total of 181 cases of solid cystic tumors of the pancreas reported in the Japanese literature, including our case, were reviewed to evaluate the clinical differences between patients aged 50 years or over and those younger than 50 years.

Giant leiomyosarcoma of the remnant stomach: report of a case.

We describe herein the case of a 73-year-old woman who developed a giant leiomyosarcoma in the remnant stomach 4 years after undergoing a distal gastrectomy for gastric carcinoma. Abdominal ultrasonography and computed tomography revealed a huge tumor, 22 cm in maximum diameter, in the left hypochondrial region. Selective abdominal angiography showed a hypervascular tumor fed by the branches of the splenic artery and left inferior phrenic artery. The tumor arose from the posterior wall of the remnant stomach, and demonstrated marked extragastric growth and direct invasion of the pancreas, transverse colon, and diaphragm on the left side. Total resection of the remnant stomach with en bloc resection of these adjacent organs was subsequently carried out. We reviewed the Japanese literature on this extremely rare tumor and evaluated its clinical profile. In comparison with leiomyosarcoma of the unresected stomach, that of the remnant stomach more frequently showed endogastric-type growth and was accompanied by ulceration of the gastric mucosa. The prognosis of patients with leiomyosarcoma of the remnant stomach appears to be greatly affected by the presence of liver metastases and the tumor diameter, similar to that of patients with leiomyosarcoma of the unresected stomach.

Incidence of aneurysms in Takayasu's arteritis.

The angiographic findings of Takayasu's arteritis in a series of 113 patients were reviewed. Predominant findings were stenotic or occlusive changes, but fusiform or saccular aneurysms were also found in 36 patients (31.9%) in the various sites of aorta and its major branches. Multiple aneurysms were found in 15 patients. The most common site of aneurysms was the ascending aorta (16 patients); in 7 of the patients these were complicated by aortic regurgitation. Aneurysms developed in the aortic arch in 3 patients, in the descending aorta in 11, in the abdominal aorta in 7, and in the major branches of the aortic arch in 9 patients. In 2 patients, follow-up angiograms showed enlargement of the aneurysms, and rupture of the aneurysm occurred in 1 patient. Aneurysms were found even in young patients. A fifteen-year-old female showed a huge aneurysm in the ascending aorta as the initial manifestation of this disease. Thickening of the walls of aneurysms was common and characteristic. This study revealed the moderately high incidence of aneurysms of various sites of arteries in patients with Takayasu's arteritis. The authors conclude that aneurysm, as well as occlusive changes, can be a primary lesion.
