Prospective validation of a lymphocyte infiltration prognostic test in stage III colon cancer patients treated with adjuvant FOLFOX.

Background: The prognostic value of lymphocyte infiltration (LI) of colorectal carcinoma (CC) has been demonstrated by several groups. However, no validated test is currently available for clinical practice. We previously described an automated and reproducible method for testing LI and aimed to validate it for clinical use.

Multiple peritoneal calcifying fibrous tumors revealed by ischemic colitis.

We report the case of a 41-year-old man presenting with multiple calcifying fibrous tumor (CFT) revealed by ischemic colitis. Peritoneal nodular lesions involved omental, mesenteric, mesorectal, and mesocolic serosal surfaces. Histologically, nodules were composed of dense bundles of collagen, calcifications, and lymphoplasmacytic infiltrate.
