胃リンパ管腫の1症例

LYMPHANGIOMA OF THE STOMACH, A CASE REPORT

　最近私共は，胃良性腫瘍の中でも極めてまれとされている胃リンパ管腫の1症例を経験したので，若干の文献的考察を加えて報告する．

　This is a report of a case of lymphangioma recently encountered which was preoperatively diagnosed as a benign, submucosal tumor of the stomach, and confirmed later by histological examination as belonging to lymphangioma.

　Case: a 49-yaer-old male, complaining of epigastric pain.

　Present History: on July 16, 1968, the patient was referred to the authors' department as he had continuous pain in the epigastrium. At X-ray examination, a round, sharply demarcated radiolucency the size of a thumb was found in the lesser curvature side at the level of the incisura.

　By fiberscopy it was visualized as a dome-like protuberance. Its surface was smooth, colored in pale violet. Operation was accordingly performed under the tentative diagnosis of a benign, subrnucosal tumor of the stomach. In the resected specimen, a submucosal tumor, 30 × 15 × 10mm in size, was found on the posterior wall near the lesser curvature 3cm oral from the pyloric ring.

　No appreciable difference was found between the mucosa on the encapsulated tumor and that of contiguous areas. A small indentation was noted on the surface of the tumor, but there was noulcer on it. Histologically it was a cystic lymphangioma. As this variety of tumor is of extraordinarily rare occurrence, some comments are made referring to its literature hitherto published.
