1/438. Double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes: report of a case.

    A case of double cancers of the lung and esophagus associated with a sarcoid-like reaction in their regional lymph nodes is reported. A 73-year-old man with hemosputum was found to have a mass in his right lower lung field on a chest X-ray. Based on a diagnosis of lung cancer, a right middle and lower lobectomy with a dissection of the lymph nodes was performed. Microscopically, a well developed granulomatous reaction was seen in the dissected mediastinal and hilar lymph nodes. Three years after the pulmonary resection, he was admitted to our hospital because of dysphagia. A diagnosis of lower esophageal cancer was made. A lower esophagectomy with a total gastrectomy was performed. A sarcoid-like reaction comprising epithelioid cells and giant cells was seen in the regional lymph nodes. No clinical findings indicative of systemic sarcoidosis were observed. This rare condition may therefore help to improve our overall understanding of the relationship between malignant neoplasms and sarcoid-like reactions in the regional lymph nodes.

2/438. Resection of triple synchronous cancers: a case report.

    We herein present a case of synchronous triple cancer, which was successfully resected in a curative manner. These cancers consisted of primary duodenal, pancreatic and lung cancers, which were diagnosed in an asymptomatic 74 year-old male, who was referred to our department on December 14, 1996. On admission, his laboratory data showed no abnormality, including tumor markers (CEA 1.0, CA 19-9 1.0, AFP 8.1 U/ml), but he did show an impaired pulmonary function (FEV1.0: 57%). Upper gastrointestinal endoscopy showed a smooth surfaced duodenal tumor measuring 4 cm in size. The second tumor was found at the head of the pancreas by computed tomography (CT), showing a hypervascular mass measuring 3.0 cm, along with neighboring multiple cysts. In endoscopic retrograde cholangiopancreatography (ERCP), marked mucous secretion was observed through the papilla, while a filling defect was found in the dilated pancreatic duct. In a routine chest X-ray, a third tumor, which measured 1.5 cm in diameter, was recognized in the right upper lobe of the lung, and a moderately differentiated squamous cell carcinoma was also detected by a percutaneous CT guided biopsy. The pancreatic and duodenal tumors were surgically resected by a pancreatoduodenectomy (Stage I) in January 1997 and, 5 months later, a lung tumor underwent partial resection (Stage I). This patient tolerated these surgical procedures well and presently leads a normal, healthy life after discharge. In summary, a successful resection of synchronous triple cancers, which has never been previously reported in this specific combination, is described.

3/438. Primary cancer of the larynx associated with primary lung cancer. Report of 21 cases, 14 with autopsy findings and 7 biopsies.

    The present paper reports 21 cases (14 autopsies and 7 biopsies) of associated primary cancers of the larynx and the lung. This association is by no means uncommon, the laryngeal lesion being usually the first to appear. Mulitple primary cancers--of the same or of a different histologic type--tend to occur in the same organ or organ system, either simultaneously or after a time interval. In case of synchronous primary malignant tumour of the larynx and lung the most lethal cancer (the lung cancer) must be managed first. Cancer patients are more likely than other individuals to develop a second primary malignant tumour. Laryngectomized patients should be followed-up possibly by means of cytologic examinations of bronchial secretions and chest x-rays at short intervals for early detection of a possible second primary malignant pulmonary lesion.

4/438. Primary liver carcinoma complicating membranous obstruction of the inferior vena cava.

    A rare autopsy case of primary liver carcinoma complicating a pre-existing, incomplete membranous obstruction of the inferior vena cava (MOVC) is reported. The patient, a 67-year-old Japanese male, was admitted to hospital following a 2 year illness of a left chest wall tumor and a 3 month illness with progressive abdominal pain. Computed tomography scans of the abdomen displayed space-occupying lesions in the third and seventh hepatic segments, respectively. One month later, the patient developed edema of the lower extremities and marked venous dilatation of the abdominal trunk. At that time, Doppler examination revealed the presence of intrahepatic large venovenous collaterals. The patient subsequently succumbed 82 days after hospitalization. At subsequent autopsy, the inferior vena cava was completely obstructed by tumor thrombus, which was formed caudally and cranially to a thin membrane and mimicked the valve, with calcification and elastic lamina, at the phrenic portion. Intrahepatic large collateral pathways were found between submembranous and supramembranous hepatic veins. Anomalous absence of the ostia of the middle hepatic vein was found. In addition, the portal venous trunk was occluded by tumor thrombus. histology of hepatic tumors revealed a combined hepatocellular and cholangiocellular carcinoma in the non-cirrhotic liver with severe acute centrilobular congestion. In MOVC patients such as the case presented, malignancy-induced thrombosis was deemed to be an important factor in prognosis.

5/438. A case of synchronous double primary lung cancer with neuroendocrine features.

    We report a case of unique double primary lung cancers with neuroendocrine features in a 63-year-old male smoker. The mass in the left lower lobe (LLL) was a small cell/large cell carcinoma with spindle cell sarcomatous areas and organoid structure. The mass in the left upper lobe (LUL) was a tubular adenocarcinoma with neuroendocrine features including organoid nests showing occasional rosette formation, nuclear palisading in the periphery of the nests and positive immunoreaction for CD56, chromogranin a and synaptophysin. The difference in histological structures between the two masses led us to diagnose double primary lung cancer. The combination of small cell lung carcinoma and spindle cell carcinoma is very uncommon. The relationship between LLL and LUL tumors remains unclear. Multiple lung cancers with neuroendocrine features have only rarely been reported in the literature. The patient in our case died of widespread cancer 2 years and 4 months after the surgery without adjuvant chemotherapy, a longer postoperative survival time than in cases of ordinary extensive small cell lung cancer. Multiple lung cancers with neuroendocrine features are extremely rare and similar cases have not been reported in the literature. Neuroendocrine differentiation has attracted widespread attention and, therefore, examining neuroendocrine features in lung cancers is important.

6/438. Multiple piloleiomyomas associated with solitary angioleiomyoma.

    A 58 year-old male had reddish scattered papules strictly confined to the right side of his upper back and neck, right shoulder, and right upper arm. Additionally, he also noticed a subcutaneous nodule on his left thigh. Histopathological examinations revealed that the papules on the back, nape of the neck, shoulder, and arm were multiple piloleiomyomas, as shown by the proliferation of bundles of smooth muscles in the dermis. The subcutaneous nodule of the thigh was angioleiomyoma with a well-circumscribed lesion composed of smooth muscles and blood vessels. Ipsilaterality and segmentality of the distribution of the papules of piloleiomyomas and probable family history that his mother had similar papules with a similar distribution suggest the nevoid character of our case. Piloleiomyomas are often reported to be associated with leiomyoma of the uterus or other organs. This is the first reported case of multiple piloleiomyomas with solitary angioleiomyoma in the literature.

7/438. brain metastases from adenoendocrine carcinoma of the common bile duct: a case report.

    A 68-year-old man with metastatic brain tumors from adenoendocrine carcinoma of the common bile duct is reported. A common bile duct tumor and a metastatic liver tumor had been resected 6 years and 3 years prior to admission, respectively. Microscopically they showed two components; moderately differentiated tubular adenocarcinoma and neuroendocrine carcinoma. He presented with headache and vomiting and MRI revealed two metastatic brain tumors. They were successfully resected and radiotherapy was carried out. Histological diagnosis of the metastatic brain tumors was neuroendocrine carcinoma, but carbohydrate antigen (CA)-19-9 and carcinoembryonic antigen (CEA)-immunoreactive cells were observed without glandular pattern. Immunohistochemically serotonin and pancreatic polypeptide were detected, but somatostatin was not. As the endocrine cells demonstrated in the normal extrahepatic bile ducts are only somatostatin-containing D cells, these cells are considered to originate as part of a metaplastic process. To our knowledge, this represents the second case of adenoendocrine carcinoma of the common bile duct.

8/438. Congenital hemihypertrophy and epithelioid haemangioendothelioma in a 10-year-old boy: a case report.

    Epithelioid haemangioendothelioma has not been previously described in a patient with congenital hemihypertrophy and diabetes mellitus. Hepatic nodules were incidentally discovered on a routine US examination searching for known associated abnormalities. Pulmonary nodules were present on chest X-ray and CT of the lungs. The diagnosis was confirmed by open biopsy of a hepatic nodule. Despite significant disease progression the patient remains symptom free.

9/438. Excessive nodular hyperplasia of brunner glands associated with gastric hypersecretion and lipomatous atrophy of the pancreas.

    The case of a 34-year-old woman complaining of diarrhoea and abdominal pain is presented. Contrast radiography and endoscopy showed multiple polypoid tumours in the second part of the duodenum. Moreover, a severe fatty infiltration of the pancreas was shown by magnetic resonance and computed tomography scans. Due to pain, pancreatoduodenectomy (Whipple operation) was performed, and subsequent histopathologic examinations showed excessive Brunner gland hyperplasia of the duodenum and severe lipomatous atrophy of the pancreas. The occurrence of these two rare conditions in one patient has not been described previously, and it is conceivable that the lipomatous atrophy and exocrine insufficiency of the pancreas may have caused a compensatory stimulation of the submucosal structures of the duodenum.

10/438. Double cancer of the gallbladder and common bile duct associated with an anomalous pancreaticobiliary ductal junction without a choledochal cyst: report of a case.

    We report herein the case of a 37-year-old woman found to have double cancer of the gallbladder and common bile duct associated with an anomalous pancreaticobiliary ductal junction (APBDJ) without a choledochal cyst (CC). Abdominal ultrasonography showed an isoechoic mass in the gallbladder, and percutaneous transhepatic biliary drainage tubography revealed incomplete obstruction in the upper portion of the common bile duct and APBDJ. The patient underwent cholecystectomy, partial hepatic resection, pancreatoduodenectomy, and portal vein reconstruction. Pathological examination of the tumors from the gallbladder and bile duct revealed papillary carcinoma and poorly differentiated adenocarcinoma, respectively, and direct continuity was not observed between the tumors. A review of the literature on six cases of multiple primary carcinoma of the biliary tract associated with APBDJ without CC is presented following this case report. Double cancer of the biliary tract was found synchronously in five patients and metachronously in one. gallbladder cancer showed subserosal invasion in four patients, while bile duct cancer invaded the pancreas in one patient and reached the serosa in two patients. Considering the potential for cancer to arise in the biliary tract and the difficulties associated with monitoring it, cholecystectomy and resection of the extrahepatic common bile duct may be the most appropriate treatment for patients with an APBDJ without a CC.
