[Case of lymphomatoid gastropathy detected during follow-up after chemoradiotherapy for esophageal cancer].

A man in his 70s underwent chemoradiotherapy for squamous cell carcinoma of the esophagus in 2009. A follow-up gastroendoscopy performed 3 years later revealed a reddish depressed lesion in the greater curvature of the middle stomach body. On the basis of histological and immunohistochemical findings and clinical features, including endoscopic findings, a diagnosis of lymphomatoid gastropathy was made. Follow-up studies revealed a decrease in the size of the lesion and the development of chronic gastritis. Although lymphomatoid gastropathy is rare, recognition of this disease is important because misdiagnosis as lymphoma may lead to unnecessary radical therapeutic procedures.

[A case of duodenal epithelioid hemangioma causing gastrointestinal bleeding].

A case of epithelioid hemangioma of the duodenum causing bleeding was encountered. A 32-year-old man was admitted because of anemia. Endoscopic examination revealed a submucosal tumor with central depression in the 2nd portion of the duodenum. It was considered to be the bleeding focus of anemia. A partial resection of the duodenum was performed. The macro- and microscopic examination of the specimen revealed an epithelioid hemangioma. Hemangiomas of the intestinal tract are rare, representing only 0.3% of all tumors of the intestinal tract, and among them, hemangiomas of the duodenum are extremely rare, representing only 3.4% of those of the intestinal tract. Most hemangiomas of the duodenum are cavernous hemangiomas or capillary hemangiomas. We report the first case of epithelioid hemangioma of the duodenum.

Clinical features of primary lung cancer adjoining pulmonary bulla.

A few investigators have suggested a possible association between lung cancer and a pulmonary bulla. But its correlation is not yet fully understood. Five hundred and forty-five cases with primary lung cancer were studied retrospectively by re-evaluation of their chest computed tomography (CT)-scans. Cancer adjoined a bulla in 19 cases. In these instances, each case's clinical course, pathological findings and surgical results were investigated. All cases were men and were heavy smokers. Three of them were under 50 years of age. Bulla/cancer incidence was 3.5%. Initial symptoms were common respiratory symptoms in five cases (26.3%) and hemosputa and hoarseness in one case (5.3%), respectively. In comparison with the control group, a ratio of squamous cell carcinoma (SCC) and large cell carcinoma was significantly high (P<0.05) and differentiation of the carcinoma was poor (P<0.001). Although the pathological staging and lung function data revealed no statistical difference, the survival curve of bulla/cancer group was significantly worse (P<0.01). Primary lung cancer adjoining pulmonary bulla tends to be poor in prognosis, even if it was small in size. A low-density mass shadow adjoining the bulla should be frequently examined by CT-scans and should proceed to an exploratory thoracotomy if it have increased in size.
