Diffuse Esophageal Leiomyomatosis: A Case Report

Leiomyomas are the most common benign tumors found in the esophagus. They are mostly solitary and multiple diffuse lesions are rare, occurring in only 2.4% of cases (1). We describe the case of a 13-year-old boy with a history of Alport syndrome who complained of progressive dysphagia and postprandial vomiting, and in whom diffuse leiomyomatosis of the esophagus was diagnosed. Chest PA showed mediastinal widening, and a barium study revealed diffuse esophageal wall thickening with dilatation, and obstruction at the level of the distal esophagus. Manometry showed increased pressure in the lower esophagus, and CT demonstrated diffuse thickening of the entire esophageal wall and an intraluminal mass in the distal esophagus. Follow-up CT three years later showed further esophageal wall thickening, as well as luminal narrowing. By means of distal esophagectomy, diffuse leiomyomatosis involving the entire esophageal wall and intraluminal mass was diagnosed.

Low Grade MALT Lymphoma of Rectum: A Case Report

We report a case with low-grade MALT lymphoma of the rectum in a 32-year-old man. Primary lymphoma of thecolon is rare and comprises less than 1 % of large bowel malignancies. Recently, large part of colonic lymphomahave been shown to be MALT lymphoma, which is a distinct type of B-cell lymphoma. The radiologic findings of thiscase are mucosal nodularity with shallow ulcers in the rectum, as seen on bar-ium enema, and rectal wallthickening, as seen on CT. There was no evidence of intra-abdominal lym-phadenopathy nor hepatosplenomegaly. Suchradiologic findings are rather similar to the findings in cases of inflammatory bowel disease, rending thedifferential diagnosis difficult.
