chemodectoma

Chemodectoma, also known as a paraganglioma, is a rare type of tumor that develops from specialized cells called chemoreceptors located near blood vessels, primarily in the head and neck. These tumors often grow slowly and may not cause symptoms initially. They can sometimes affect nerve function, leading to symptoms like a neck lump, hearing changes, or blood pressure issues. While most chemodectomas are benign, they can rarely be malignant or spread. Diagnosis typically involves imaging and biopsy, and treatment usually involves surgery or radiation. Early detection and management are important to prevent complications.
