Abdominal neoplasms Archives - Revista Brasileira de Ginecologia e Obstetrícia

Desmoid tumor is a noncapsulated neoplasia, locally aggressive, originated from the fibroblasts of the musculo-aponeurotic tissues. Even though with no malignant behavior, such as the ability of generating metastasis or of invasion, the desmoid tumor has a high tendency for local growth, causing deformities in the adjacent organs, pain and sometimes organ dysfunction, depending on the area involved. We report the case of a large intra-abdominal desmoid tumor, invading pelvic organs in a 53 year-old patient. The neoplasia has been totally extirpated and, at the moment, five years after the surgery, the patient presents no clinical or radiologic sign of lesion relapse.
