Abstract
Among leiomyosarcomas of the gastrointestinal tract, those arising in the esophagus are relatively rare. We experienced a resected case of intra- and extra-luminally growing leiomyosarcoma of the esophagogastric junction with tumors in the mediastiunm and peritoneal cavity.
A 68-year-old man was admitted to the hospital because of appetite loss. A chest X-ray photograph showed a demarcated large mass shadow behind the cardiac shadow. The mass was examined by a barium examination, gastrointestinal fiberscopy, CT, MRI and angiography, and it was diagnosed preoperatively as leiomyosarcoma occupying the lower esophagus and upper stomach. An operation was carried out. The mass extended from the lower esophagus to the cardia. The border was relatively clear without any invasion or metastasis to other organs or lymph nodes. An esophagogastrectomy was carried out. The tumor consisted of two parts; an extraluminal part (6.0×7.0×8.5cm) and an intraluminal part (4.0×2.5×2.0cm) at the esophagogastric junction with a center ulceration. The histological diagnosis was esophageal leiomyosarcoma arising in the esophagogastric junction.
