Adenocarcinomas are carcinomas derived from glandular tissue.
Mucinous adenocarcinomas are adenocarcinomas which produce mucus, and may arise from several primary sites including the colon and ovaries. Pseudomyxoma peritonei is a rare clinical entity with much confusion about its etiology, clinical manifestations, treatment, and prognosis. Pseudomyxoma peritonei is defined by extensive accumulation of mucinous adenocarcinoma at specific locations within the abdomen and pelvis. Most commonly the origin of the mucinous adenocarcinoma is from a ovarian or appendiceal tumor. Some authors reserve the term pseudomyxoma peritonei for intraabdominal spread of appendiceal tumors only, but others apply this term regardless of the pathogenesis.
