Ulcerative Colitis Complicating Pseudomembranous Colitis of the Right Colon

Lymphoma complicating ulcerative colitis.

Malignant lymphoma complicating ulcerative colitis.

Carcinoma of the colon as a complication of chronic ulcerative colitis is relatively common, whereas malignant lymphoma is apparently rare. We report two cases of patients with malignant lymphoma complicating ulcerative colitis, a CD 30 + T-cell lymphoma of the intestine and a low grade B-cell non-Hodgkin's lymphoma of MALT type. It is important to be aware of the possibility of malignant lymph...

C. difficile is an anaerobic Gram-positive rod which secretes two types of toxin (A and B), which cause disruption to the barrier function of the colonic mucosa. They ar...

CDAD (Clostridium difficile - Associated Disease or Diarrhoea) is the term which is generally and quite aptly used for the disease in literature on the subject. In most cases,...
