An interesting case of malignant paraganglioma of the mandible with calvarial metastasis

Abstract

Paraganglioma is a rare neuroendocrine tumor arising from the neuroectodermally derived paraganglionic cells scattered throughout the body. Other neuroendocrine tumors include carcinoids, islet cell tumors, medullary carcinoma of thyroid, melanoma, mastocytoma, merkel's cell tumor of the skin, neurocytomas, oat cell carcinoma, pinealoma, and pituitary adenoma. Very few cases have been reported intraorally. Only few cases of neuroendocrine tumor of mandible have been reported till date. This is an interesting case of malignant paraganglioma of the mandible in a 30-year-old male patient with metastasis to the calvarium.
