A case of carcinoid tumor of the gallbladder, which was sensitive to mitomycin-C is reported. A 49-year-old male was admitted to our hospital with a 2-month history of epigastralgia. He underwent right extended lobectomy of the liver, pancreaticoduodenectomy and lymph node dissection. Histology revealed a carcinoid tumor of the gallbladder with invasion of the liver and lymph node metastasis. About 2 months after the operation, right supraclavicular lymph node metastasis was detected and CT scan revealed abdominal paraaortic lymph node metastasis. The patient was given cis-platinum, but the right supraclavicular lymph node metastasis increased in size and number. After administration of mitomycin-C, the paraaortic lymph node metastasis disappeared. Carcinoid tumor obtained from the right supraclavicular lesion was inoculated into BALB/c nude mice, and sensitivity to anticancer drugs was assayed. This carcinoid tumor was sensitive to mitomycin-C but not to cisplatinum, adriamycin, or nimustine.

A clinicopathologic study was done on 21 cases of superficial flat-type early gastric carcinoma (IIb type EGC). In one case there was the two IIb type EGC. Nine patients had no symptoms, whereas the other 12 had either epigastralgia, hematemesis, or anorexia. The preoperative diagnosis was accurate in 15 patients; eight were demonstrated by barium study, and 13 by endoscopy. The suspicious finding of IIb type EGC was either the disappearance or irregularity of the areae gastricae by barium study and a mucosal color change by endoscopy. Well-differentiated or moderately differentiated adenocarcinomas showed a slight redness of the affected mucosa whereas the poorly differentiated adenocarcinomas were pale in color. Histologically, many well-differentiated or moderately differentiated adenocarcinomas occupied the entire thickness of the mucosal layer whereas most of the poorly differentiated adenocarcinomas spread horizontally with preservation of non-cancerous glands and foveolae. The growth pattern was super type in ten lesions and small mucosal type in 12 and no pen-type growth was seen. Concerning the cell nuclear DNA ploidy pattern, 21 showed a low ploidy pattern and only one had a high ploidy pattern. The IIb type EGC seemed to have a less malignant potential from the viewpoint of growth pattern and DNA ploidy pattern. Care must be taken at the proximal line of excision of the tumor so as not to leave behind residual carcinoma cells.

Leiomyomas are rare tumors found as a rule in the stomach (1-2% of all gastric tumor cases) and occasionally in the intestine. Unless they grow large or become ulcerated gastric leiomyomas run a silent course. Otherwise there is epigastric pain, hemorrhage or impaired gastric evacuation. When complicated, the disease presents diagnostic difficulties and is treated surgically. Gastrotomy with dissection of the tumor or local resection of the gastric wall proved a reliable therapeutic means. Gastric resection is indicated in ill-defined tumors or in suspected malignancy.

Hepatic inflammatory pseudotumor (HIP) is rare. To our knowledge, there have only been 27 cases reported since 1953. We studied additional five cases, male, aged 13-56 years, with a history of the disease of 20 days-1 year. Major complains were epigastric pain, fever of unknown causes, and epigastric mass. All five HIPs were solitary and surgically resected with a final diagnosis made pathologically. HIPs mimic the characters of liver cancer on ultrasonography and CT scanning, however, the following several points could be used to establish the diagnosis: patients with a long history of hepatic tumor still in a rather good condition; patients with no cirrhosis and negative AFP test results; tumors that are well encapsulated, etc. Surgical exploration should be attempted in all patients unless in those with poor risks in which steroid therapy may prove useful.

A successful surgical case of malignant undifferentiated (embryonal) sarcoma of the liver (USL), a rare tumor normally found in children, is reported. The patient was a 21-year-old woman, complaining of epigastric pain and abdominal fullness. Chemical analyses of the blood and urine and complete blood counts revealed no significant changes, and serum alpha-fetoprotein levels were within normal limits. A physical examination demonstrated a film, slightly tender lesion at the liver's edge palpable 10 cm below the xiphoid process. CT scan and ultrasonography showed an oval mass, confined to the left lobe of the liver, which proved to be hypovascular on angiography. At laparotomy, a large, 18 x 15 x 13 cm tumor, found in the left hepatic lobe was resected. The lesion was dark red in color, encapsulated, smooth surfaced and of an elastic firm consistency. No metastasis was apparent. Histological examination resulted in a diagnosis of undifferentiated sarcoma of the liver. Three courses of adjuvant chemotherapy, including adriamycin, cis-diaminodichloroplatinum, vincristine and dacarbazine were administered following the surgery with no serious adverse effects. The patient remains well with no evidence of recurrence 12 months after her operation.

This is a retrospective study of a series of seven patients with pancreatic metastases studied by ultrasonography and computed tomography. They were detected during tumor staging, or in the follow-up period of over 10 years of patients with advanced known malignancy. Lesions were multiple in two patients and solitary in five; solid in six cases and cystic in one. Clinically, four cases were asymptomatic and three cases presented with jaundice or epigastric pain. Ultrasonography and computed tomography findings were non-specific. Consequently it was not possible to differentiate solitary metastases from primary solid adenocarcinoma and cystadenocarcinoma of the pancreas. In these cases, computed tomography- or ultrasonography-guided biopsies had to be performed to obtain histological proof. However, multiple lesions discovered in a patient with a known malignancy can be assumed to be due to metastases.

A 51 year-old woman with vomitus, intermittent epigastric pain and heartburn had chronic sideropenic anemia. Gastroscopy revealed a subcardial, submucosal tumor. The tumor was removed totally by endoscopic polypectomy. Histologically it was identified as a carcinoid. The endocrinologic examination showed hypergastrinemia caused by chronic atrophic gastritis. The association of this gastric carcinoid with chronic atrophic gastritis type A, hypergastrinemia, hyperplasia of the gastrin-producing antral cells and micronodular hyperplasia of endocrine cells in the gastric fundus, confirms the hypothesis about the pathogenesis of these extremely rare gastric tumors.

Reported in this paper is a rare case of "amputation neuroma" of the cystic duct which had developed in the wake of cholecystectomy. The tumor had grown into the common bile duct over years and, eventually, had caused complete obliteration of the latter. Recurrent cholangitis had resulted in epigastric pain, febrile attacks, and icterus. Secondary biliary liver cirrhosis and a chronic biliodigestive fistula were additional complications. An acute cholangitis attack caused liver abscesses, and the patient died of septic shock.

Primary pancreatic lymphoma is extremely rare. A case of the primary pancreatic lymphoma was described. A 74-year-old man was admitted to our hospital on May 26, 1990, because of epigastralgia and 5-kg weight loss. On admission, physical examination revealed mild epigastric tenderness without hepatosplenomegaly and superficial lymphadenopathy. The serum amylase level and trypsin level were normal but serum CA19-9 was slightly elevated. The diagnosis of the pancreatic cancer (body and tail) was strongly suspected on subsequent examination by US, CT, ERP and angiography. Partial pancreatectomy and splenectomy were performed. Pathological examination of the tumor in the pancreas showed diffuse non-Hodgkin's lymphoma and B-cell origin. Peripancreatic fat was involved but peripancreatic lymph nodes and spleen were intact, which strongly suggested that the isolated lymphoma was pancreatic origin.

A 77-year-old male, complaining of epigastralgia, was admitted to hospital. An upper GI series revealed a hemispheric filling defect at the greater curvature of the lower gastric body and two submucosal tumor-like lesions of the antrum. Closer inspection revealed a tumor measuring 60 x 42 mm, with an irregular ulcer, and two submucosal tumor-like lesions with bridging folds, measuring 42 x 28 mm and 20 x 14 mm, respectively. Histologically, the microscopic features in the ulcerated tumor showed a variety of tumor cells with clear PAS-positive cytoplasms and marked atypical nuclei forming glandular structures that predominated. Additionally, a clear cell carcinoma, a papillary adenocarcinoma, a signet-ring cell carcinoma, and a choriocarcinoma were partially seen. Finally, in the submucosal tumor-like lesions, diffuse small tumor cells with scanty PAS-positive cytoplasms without granular structures were seen.
