All are true regarding mesothelioma except ?
## Core Concept
Mesothelioma is a rare and aggressive form of cancer primarily associated with exposure to **asbestos**. It originates from the mesothelial cells lining the pleura, peritoneum, or pericardium. The disease has a long latency period, often 20-40 years, between asbestos exposure and symptom onset.
## Why the Correct Answer is Right
The correct answer, although not directly provided, would relate to a statement that does not accurately describe mesothelioma. Typically, mesothelioma is characterized by its association with asbestos exposure, its aggressive nature, and its origin from mesothelial cells. Statements regarding its epidemiology, pathology, and clinical presentation are crucial.
## Why Each Wrong Option is Incorrect
- **Option A:** Without specific details on Option A, we can infer that any statement claiming mesothelioma is commonly associated with genetic mutations (rather than environmental exposure like asbestos), or suggesting a short latency period, or indicating a high cure rate with conventional treatments, would be incorrect.
- **Option B:** Similarly, if Option B suggests mesothelioma is a benign condition or easily treatable with surgery alone, this would be inaccurate.
- **Option C:** If Option C mentions a different primary cause (e.g., viral infection) or a very short latency period (e.g., months), it would not align with established knowledge on mesothelioma.
- **Option D:** Assuming Option D provides an accurate statement about mesothelioma (given it's the correct answer), any details provided would validate its characteristics, such as poor prognosis, association with asbestos, or specific histological types (epithelioid, sarcomatoid, biphasic).
## Clinical Pearl / High-Yield Fact
A key point to remember is that **pleural mesothelioma** is the most common form, accounting for about 80-85% of cases, and it often presents with symptoms like dyspnea, chest pain, and weight loss. A significant clinical correlation is the potential for **calretinin** to be used as a diagnostic marker, helping differentiate mesothelioma from other types of cancer.
## Correct Answer: D.
