**Core Concept**
Nasal angiofibroma is a rare, benign vascular tumor that typically occurs in adolescent males, often presenting with nasal obstruction, epistaxis, and facial deformity. This tumor is characterized by its rapid growth and potential for local invasion.

**Why the Correct Answer is Right**
Nasal angiofibroma is most commonly seen in adolescent males between the ages of 10 and 25 years, with a peak incidence around 15-19 years. The exact cause of this tumor is unknown, but it is thought to be related to hormonal influences, particularly the high levels of androgens present during puberty. The tumor's rapid growth and vascular nature make it prone to bleeding and local invasion.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because nasal angiofibroma is not typically seen in young children, as their hormonal levels are not yet high enough to promote tumor growth.
**Option B:** This option is incorrect because while nasal angiofibroma can occur in older adults, it is most commonly seen in adolescent males.
**Option C:** This option is incorrect because nasal angiofibroma is not typically seen in females, although it can occur in rare cases.

**Clinical Pearl / High-Yield Fact**
Nasal angiofibroma is a classic example of a "masquerader" tumor, presenting with a variety of nonspecific symptoms that may lead to delayed diagnosis. A high index of suspicion and a thorough physical examination are essential for early detection and treatment.

**Correct Answer:** C. 15-25 years.
