Tubulovillous adenomatous polyp

Case contributed by Dr Varun Babu


Bloody stools for evaluation. Colonscopy showed a rectosigmoid mass lesion.

Patient Data

Age: 75 years
Gender: Male

Rectosigmoid shows a large polypoidal enhancing intraluminal mass lesion arising from the mesenteric border. No transmural extension. Couple of subcentimetric enhancing pericolonic lymph nodes present. No mesenteric mass lesions. No iliac lymphadenopathy. 

Case Discussion

Rectosigmoid mass polypoidal mass lesions in an elderly gentleman should always raise the possibility of a colonic neoplasm.

Histopathology following colonscopy revealed glands of varying sizes in the polyp; the glands are closely packed together, lined by tall cells with hyperchromatic nuclei, and with cytoplasm showing vacuolations. The histology also showed a good number of inflammatory cells, favoring a tubulovillous adenomatous polyp with high grade dysplasia.
