EXTRAMEDULLARY PLASMACYTOMA MIMICKING PRIMARY COLONIC-CARCINOMA IN A PATIENT WITH CROHNS-DISEASE - CASE-REPORT AND LITERATURE-REVIEW

We present the case of a 45-year-old man who underwent segmental resec tion for what was considered clinically to be a primary colonic carcin oma. Histopathologic evaluation revealed the tumor to be a malignant p lasmacytoma of the colon. Additionally, the entire segment of distal i leum and colon was involved by an inflammatory process with the featur es of Crohn's disease, accompanied by focal glandular dyplasia of the colonic mucosa. This case reemphasizes that plasmacytoma of the colon can closely mimic carcinoma of the colon in its presentation. The asso ciation between plasmacytoma of the colon and Crohn's disease has not, to our knowledge, been described previously.
