  • Abstract
  • Look Inside

 The patient, a 35-year-old man, came to our hospital for further minute check-up with complaints of diarrhea, melena and abdominal fullness in September 1983. Plain radiography of the abdomen showed almost round radiolucencies of varying size corresponding to the ascending colon near the hepatic flexure. Barium-filled roentgenogram of the colon showed almost round shadow defects, 2-18mm in diameter, scattered about in the ascending colon. Double contrast study of the colon showed a sessile pneumatic lesion with smooth surface, which was very radiolucent. Colonofiberscopic picture revealed elevated lesions of various size with smooth surface. On the surface of the lesions was seen no redness, erosion, or bleeding. The overall picture showed features of submucosal tumor. Although our diagnosis was pneumatosis cystoides of the ascending colon, we were unable to rule out submucosal tumor or some malignant tumor. With the consent of his family we decided to excise the lesions.

 The resected specimens showed very elastic elevated lesions which were simply flattened with the insertion of a needle. The content was no other than air with no odor. Histologically, the wall of the cysts consisted of flattened endothelial cells and multinucleated cells with no lining such as epithelial cells.

 The patient was a painter. The use of organic solvent for more than 10 years was strongly suspected for the cause of such lesions.
