  • Abstract
  • Look Inside

 A 63 year-old woman visited the hospital with a complaint of anemia. Neither she nor her family had tuberculosis in their medical histories. Barium enema study revealed marked shortening of the ascending colon in a longitudinal direction, accompanied by disappearance of the caecum, formation of a pseudodiverticulum, and the presence of inflammatory polyps. These findings suggested a tuberculous atrophic scar lesion. Observed in this region of the scar lesion was a low Ila-like elevation of coarse surface measuring about 5.0 cm in size. A forceps biopsy of the elevation disclosed adenocarcinoma. A histological examination of the resected specimen revealed no evidence of tuberculosis but an area of atrophy of the tubular epithelium and old fibrosis of the submucosa. The Ila-like elevation was well differentiated adenocarcinoma without adenomatous change. This patient, though suspected of having colon tuberculosis, presented an extremely rare pathological condition viz. a colon cancer in an atrophic scar region, Referring to current literature on the subject, discussion was held on the characteristics of, and the relation between the two diseases.
