Pyogenic granuloma of the terminal ileum diagnosed by colonoscopy: the relevance of ileocecal valve intubation.

Pyogenic granuloma is a benign vascular lesion that is most frequently found in the epidermis or mucosa of the oral cavity. Its finding in the ileum is rare, there are only a few case reports. In most reported cases, diagnosis is made with capsule endoscopy or double-balloon enteroscopy. We present a case of a lesion in the ileum, approximately 15 cm from the ileocecal valve, documented by colonoscopy.

Multiple lymphomatous polyposis: rectal prolapse as an atypical presentation of the disease.

Multiple lymphomatous polyposis is a rare entity that can involve different types of both B-cell and T-cell lymphomas, including mantle cell lymphoma. A 57-year-old male patient is presented with prolapse of the rectal canal associated with data of lower digestive tract bleeding. A colonoscopy and subsequent upper endoscopy were performed with findings compatible with lymphomatous polyposis. After a biopsy study, mantle cell lymphoma was diagnosed and chemotherapy treatment was started. The endoscopic finding of multiple lymphomatous polypoposis associated with an adequate histopathological diagnosis improves the treatment success rate in patients with different types of gastrointestinal lymphomas.
