AI Article Synopsis
- Carotid body tumor (CBT), also known as chemodectoma, is a rare neuroendocrine tumor primarily affecting the carotid body and is often benign but can be malignant.
- A unique case is described where a CBT presented as a swelling in the parotid gland, leading to a misdiagnosis of pleomorphic adenoma based on clinical tests.
- The patient underwent superficial parotidectomy, but histopathology revealed the true nature of the tumor as CBT instead of the initially suspected adenoma.
Article Abstract
Carotid body tumor (CBT) also known as chemodectoma is a rare tumor of neuroendocrine tissue of carotid body and is the most commonly seen jugular paraganglioma. In most cases, it is benign but it can be malignant. Extra adrenal paraganglioma is rare. We present such a rare case where unusual presentation of chemodectoma was seen as a parotid swelling. This swelling was misdiagnosed as a pleomorphic adenoma on clinical examination, ultrasonography, and fine-needle aspiration cytology and superficial parotidectomy was done for the same, but on histopathological examination it was found to be CBT presenting as a parotid swelling.
