Pseudomixoma peritoneal associado a neoplasias malignas mucinosas do ceco, apêndice e reto: relato de caso e revisão da literatura

Peritoneal pseudomyxoma is a pathological condition that compromises the peritoneum, characterized by the production of large quantities of mucinous liquid, which progressively fills the peritoneal cavity, originating in general from mucinous appendicular or ovarian tumors. We report a peritonial pseudomyxoma associated with mucinous adenocarcinoma of the appendix synchronic with adenocarcinoma of the rectum in 44 years old patient, where the initial diagnosis was rectal adenocarcinoma. Tumour of the appendix and peritonial pseudomyxoma were incidental and found intraoperativelly. We focus the histological patterns of the lesions, diagnosis and the treatment, with revision of the literature.
