Duplication cyst of the gastrointestinal (GI) tract is a rare congenital anomaly, and rectal duplication cysts comprise a small fraction these cases. Most patients present for the first lime adulthood, and the origin of rectal duplication cysts is unclear. Prior series document malignant transformation in approximately 20 per cent of cases. The following case report describes carcinoma arising in a rectal duplication cyst. Given the lack of data demonstrating adequate control for patients with adenocarcinoma arising in a rectal duplication cyst and our experience with this patient, we recommend all patients undergo multidisciplinary evaluation prior to any therapy.

    Abstract  The diagnosis of gastrointestinal stromal tumor (GIST) relies on a combination of the following criteria: anatomic location, typical histopathology, and the presence of CD 117-antigen (the tyrosine kinase receptor, c-kit) or CD 34-antigen. Imatinib mesylate, a specific tyrosine...

    Granular cell tumors are generally benign oncocytoid lesions of schwannian origin that are often incidental findings in many locations. Gastrointestinal stromal tumors occur in older adults and express the c-Kit protein (CD117). Both of these tumors have been described in association with many...

    Background: Colorectal cancer usually gives rise to a specific anti-tumor immune response, but for unknown reasons the resulting immunity is not able to clear the tumor. Recruitment of activated effector lymphocytes to the tumor is important for efficient anti-tumor responses, while the presence...

    Importance: Retrorectal tumors are rare lesions that comprise a multitude of histologic types. Reports are limited to small single-institution case series, and recommendations on the ideal surgical approaches are lacking. Objective: The purpose of the study was to provide a comprehensive review...
