**Question:** All are true statements about pheochromocytoma except?

A. Pheochromocytoma is a rare tumor of the adrenal medulla that results in excess catecholamine production.
B. Symptoms of pheochromocytoma include hypertension, palpitations, headaches, and sweating.
C. Treatment options for pheochromocytoma include surgery, radiation therapy, and medication.
D. Pheochromocytoma typically occurs in the elderly population.

**Correct Answer:** .

**Core Concept:** Pheochromocytoma is a rare tumor arising from chromaffin cells in the adrenal medulla, which leads to excessive production of catecholamines like epinephrine, norepinephrine, and dopamine. These hormones play a crucial role in the body's stress response and regulation of blood pressure.

**Why the Correct Answer is Right:** Pheochromocytoma primarily affects younger individuals, with a median age of onset between 30 and 40 years. Although it can occur in the elderly population, option D is incorrect because pheochromocytoma is more common in the younger age group.

**Why Each Wrong Option is Incorrect:**

A. The statement about pheochromocytoma being a rare tumor is correct, but option A focuses on the tumor's rarity rather than its specific characteristics.

B. Pheochromocytoma can present with symptoms like hypertension, palpitations, headaches, and sweating, which are common in this disease. However, option B's mention of a single symptom (headaches) is not sufficient to differentiate it from the correct answer.

C. Treatment options for pheochromocytoma include surgery, radiation therapy, and medication. While all three options are correct for managing this disease, option C's generic phrasing does not differentiate it from the correct answer.

**Clinical Pearl:** Pheochromocytoma is often associated with genetic syndromes like multiple endocrine neoplasia type 2 (MEN2), von Hippel-Lindau disease, and neurofibromatosis type 1. Early diagnosis and treatment are crucial to minimize complications and improve patient outcomes.
