Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
A mucinous neoplasm (also called colloid neoplasm) is an abnormal and excessive growth of tissue with associated mucin (a fluid that sometimes resembles thyroid colloid). It arises from epithelial cells that line certain internal organs and skin, and produce mucin (the main component of mucus ).
Vacuoles are more prominent in mucinous tumors but can be seen in serous tumors as well. Adenocarcinoma [1] (/ ˌ æ d ɪ n oʊ k ɑːr s ɪ ˈ n oʊ m ə /; plural adenocarcinomas or adenocarcinomata / ˌ æ d ɪ n oʊ k ɑːr s ɪ ˈ n oʊ m ə t ə /; AC) is a type of cancerous tumor that can occur in several parts of the body.
The American Cancer Society recommends that all adults over 45 be tested regularly for colon cancer, even if they have no symptoms. People older than 50 are still at a greater risk of developing ...

[5] Signs and symptoms may include blood in the stool , a change in bowel movements , weight loss, abdominal pain and fatigue. [ 9 ]
Primary signet ring cell carcinoma of the colon and rectum (PSRCCR) is rare, with a reported incidence of less than 1 percent. It has a poor prognosis because symptoms often develop late and it is usually diagnosed at an advanced stage. Five-year survival rates in previous studies ranged from nine to 30 percent.
Endoscopic image of adenocarcinoma of duodenum seen in the post-bulbar duodenum. Risk factors for small intestine cancer include: [7] [8] Age: Cancer risk increases with age. The average age diagnosis is 65.(Cleveland Clinic, 2022) Race: In the U.S., small intestine cancer is slightly more common among people who identify as African Americans.
