"Pseudosarcomatous change" occurs when sarcoma-like atypical cell hyperplasia is grossly indistinguishable from malignant tumor. Pseudosarcoma often exists in those areas of the gastrointestinal track where ulcer or erosion commonly takes place. This may indicate atypical granulomatous cell proliferation during a period of healing, as well as benign atypical change in the mesenchyme due to chronic inflammatory reaction. Both the visual appearance and intestinal involvement of tuberculous colitis are variable, and tuberculosis may result in reactive mesenchymal change associated with ulcer or polyp, which is that's induced by chronic inflammation. We report here on a case of a young female pulmonary tuberculosis patient who suffered with a pseudosarcoma of the ascending colon, and this was associated with tuberculous colitis. The patient underwent successful sugical resection. We report on this case, along with a review of the relevant literature.
