All are true about Pseudomyxoma peritnonei except
**Core Concept**
Pseudomyxoma peritonei (PMP) is a rare clinical syndrome characterized by recurrent mucinous ascites causing abdominal distension, often associated with a primary mucinous tumor in the appendix or ovary. The condition is characterized by the accumulation of mucin-producing cells in the peritoneal cavity, leading to a distinctive clinical presentation.
**Why the Correct Answer is Right**
Pseudomyxoma peritonei typically presents with a triad of symptoms: abdominal distension, weight loss, and palpable abdominal masses. The mucinous ascites in PMP often contains mucin-producing cells, which are thought to arise from a primary tumor in the appendix or ovary. The mucin-producing cells in PMP secrete mucin, a high-molecular-weight glycoprotein, which accumulates in the peritoneal cavity, leading to the characteristic clinical presentation.
**Why Each Wrong Option is Incorrect**
* **Option A:** This statement is true about Pseudomyxoma peritnonei.
* **Option B:** This statement is true about Pseudomyxoma peritnonei.
* **Option C:** This statement is true about Pseudomyxoma peritnonei.
* **Option D:** This statement is false about Pseudomyxoma peritnonei, as it is often associated with a primary mucinous tumor in the appendix or ovary.
**Clinical Pearl / High-Yield Fact**
Pseudomyxoma peritonei is often associated with a primary mucinous tumor in the appendix or ovary, and the condition should be considered in the differential diagnosis of mucinous ascites in patients with abdominal distension and weight loss.
**Correct Answer:** D. It is often associated with a primary mucinous tumor in the appendix or ovary.
