Chandu a 15 year aged boy presents with unilateral nasal blockade mass in the cheek and epistaxis; likely dianosis is –
**Core Concept**
The presentation of unilateral nasal blockade, mass in the cheek, and epistaxis in a 15-year-old boy suggests a diagnosis related to a nasopharyngeal or nasal mass, likely involving the paranasal sinuses or the nasal cavity.
**Why the Correct Answer is Right**
The most likely diagnosis in this scenario is a juvenile nasopharyngeal angiofibroma (JNA), a rare, benign, but highly vascular tumor that primarily affects adolescent males. JNA typically presents with nasal obstruction, epistaxis, and sometimes a mass in the cheek or palate, due to its location in the nasopharynx. The tumor's growth can erode bony structures and cause significant bleeding, which is consistent with Chandu's symptoms.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not directly relevant to the clinical presentation of unilateral nasal blockade, mass in the cheek, and epistaxis. While a nasal polyp could cause nasal obstruction, it is less likely to cause a mass in the cheek or significant epistaxis.
* **Option B:** A mucocele is a mucus-containing cyst that can occur in the paranasal sinuses, but it is not typically associated with significant bleeding or a mass in the cheek.
* **Option C:** A nasopharyngeal carcinoma is a type of cancer that can present with nasal obstruction and epistaxis, but it is more common in older adults and is less likely to present as a unilateral mass in the cheek.
**Clinical Pearl / High-Yield Fact**
Juvenile nasopharyngeal angiofibroma is a highly vascular tumor that is more common in adolescent males and can cause significant bleeding due to its location in the nasopharynx. It is essential to consider this diagnosis in patients with unilateral nasal blockade, mass in the cheek, and epistaxis.
**Correct Answer:** C.
