Pneumatosis coli: a case report with ultrastructural study.
A case of pneumatosis intestinalis studied by light and electron microscopy is presented. The cysts are dilated lymphatic vessels. Abundant fine fatty globules are found in the cysts and in the histiocytes and multinucleated giant cells which line the lymphatics and which are present in the interstitium. The giant cell formation and florid histiocytic reaction are most probably due to leakage of fatty material from the dilated lymphatics.
