Carcinoma and Epithelial Dysplasia Complicating Ulcerative Colitis

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...

An immunoperoxidase study of epithelial marker antigens in ulcerative colitis with dysplasia and carcinoma.

An immunoperoxidase technique was applied to formalin and Helly fixed paraffin wax sections from cases of ulcerative colitis complicated by dysplasia and carcinoma for carcinoembryonic antigen and components of the colonic secretory immunoglobulin system--namely, secretory component, IgA, and J chain. Sections from both resection specimens and mucosal biopsies were available. Intensity of immun...

Large bowel mucosal dysplasia and carcinoma in ulcerative colitis.

The clinicopathological details of eight cases of ulcerative colitis complicated by carcinoma of the colon are described. There was a total of 14 primary colonic cancers, six of which were not detected before pathological examination of the resection specimens. The reason for this may be related to atypical tumour growth patterns. Three occurred in flat mucosa, one in a mucosal plaque lesion, a...

Fibrolamellar hepatocellular carcinoma complicating ulcerative colitis with primary sclerosing cholangitis.

This case report describes the previously undocumented association between fibrolamellar hepatocellular carcinoma and ulcerative colitis complicated by primary sclerosing cholangitis.
