Benign Vascular Tumor And Tumor-like Disorders Of Small Intestine: A Clinicopathologic And Immunohistochemical Study

Background and Objective Benign vascular tumor and tumor-like disorders comprise tow kinds of disorders: hemangiomas and vascular malformations and lymphangioma of small intestine. Both of them are uncommon benign lesions. In the present study, 51 cases of hemangiomas and vascular malformations and 22 cases of lymphangiomas of small intestine were analyzed in clinical manifestations and histopathology retrospectively, and 29 cases of hemangiomas and vascular malformations, all lymphangiomas and 3 cases of lymphangiectasis' of small intestine were performed immunophenotype analysis of 5 antigen markers. The purpose is to investigate the clinical and pathologic features and the characters of immunophenotype of two disorders.Materials and Methods 51 cases of hemangiomas and vascular malformations, 22 cases of lymphangiomas of small intestine and 3 cases of lymphangiectasis' were selected from the files of Pathology Department, West China Hospital of Sichuan University from Jan 1963 to Feb 2005. Related clinical data and histology were collected for all of the cases and 29 cases of hemangiomas and vascular malformations, all lymphangiomas and lymphangiectasis' of small intestine were performed Immunophenotype analysis by SP method.
