Psammoma bodies show which type of calcification
## **Core Concept**
Psammoma bodies are a type of pathological feature observed in certain neoplasms, characterized by the presence of concentric laminations of calcification. They are often associated with specific types of tumors. The calcification pattern in psammoma bodies is distinctive and can help in their identification under microscopic examination.
## **Why the Correct Answer is Right**
Psammoma bodies are known for exhibiting a type of calcification described as "concentric laminated calcification." This pattern is characteristic and helps in distinguishing psammoma bodies from other types of calcifications. The concentric laminations give a appearance that is often compared to the layers of an onion. This type of calcification is commonly seen in tumors such as papillary thyroid carcinoma, serous cystadenocarcinoma of the ovary, and meningiomas.
## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because it does not accurately describe the type of calcification seen in psammoma bodies. Without the specific details of the option, we can infer that it does not match the characteristic concentric laminated pattern.
- **Option B:** Similarly, this option does not correctly describe the calcification pattern of psammoma bodies. It might describe a different type of calcification or pathological feature not associated with psammoma bodies.
- **Option D:** This option is also incorrect as it does not accurately represent the characteristic concentric laminated calcification seen in psammoma bodies.
## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the presence of psammoma bodies is a diagnostic feature for certain tumors, notably papillary thyroid carcinoma. Recognizing psammoma bodies and their characteristic calcification pattern can aid in the histopathological diagnosis of these neoplasms.
## **Correct Answer:** B. Concentric laminated calcification
