Abstract
We present the case of a 63-year-old male with long-term anal pain. A pelvic MRI was performed showing a tumor arising from the intersphincteric extending into the submucosal layer of the posterior rectal wall. The image was compatible with a cT4N0 ano-rectal carcinoma without any distant metastasis on the CT scan. Histopathology showed neoplastic proliferation cells arranged in nodules and nidus consistent with anal glands adenocarcinoma with a positive immunohistostaining for CK7 and MUC5+ .
