Question

Which of the following is not seen in MEN 2B syndrome?

• A. Megacolon
• B. Parathyroid adenoma
• C. Mucosal neuroma
• D. Marfanoid habitus

Answer 1

The Correct Option is B

In Multiple Endocrine Neoplasia type 2B (MEN 2B) syndrome, the following manifestations are typically observed:

• Mucosal neuromas: These are benign tumors that can develop on the mucous membranes of the mouth and eyes.
• Marfanoid habitus: This is a body type characterized by tall, slender build with disproportionately long limbs and fingers, resembling Marfan syndrome.
• Megacolon: This can occur due to abnormalities in the enteric nervous system, leading to issues with bowel movements.

However, parathyroid adenoma is not associated with MEN 2B. It is more commonly seen in MEN type 1 and MEN type 2A.

Therefore, the correct answer is:

• Parathyroid adenoma
