Polyp, Sigmoid Colon, Polypectomy: | |||
- Colonic mucosa with ulceration, acute inflammation and granulation tissue. | |||
- NEGATIVE for dysplasia. | |||
Comment: | |||
This may represent a polyp seen in the context of diverticular disease. Other | |||
considerations include ischemia, idiopathic inflammation and infections. | |||
Clinical correlation is suggested. | |||

The sections show a fragment of colorectal mucosa with focal ulceration, acute inflammation and a well-vascularized stroma with plump stromal cells. Occasional stromal cells have nuclear hyperchromasia. | The sections show a fragment of colorectal mucosa with focal ulceration, acute inflammation and a well-vascularized stroma with plump stromal cells.

====Alternate==== | |||
The sections show a fragment of tissue with scant benign epithelium, acute and chronic | |||
inflammation (neutrophils and plasma cells predominantly), abundant blood vessels with | |||
reactive endothelial cells and plump stromal cells. Occasional stromal cells have nuclear hyperchromasia but do not show significant atypia. | |||
