Paraganglioma is a neoplasm of paraganglia small cell collection of neural crest origin associated with the cranial nerves and their ganglia, and the ontogenic gill arches.
In the head and neck, carotid body tumors are the most common and then the tumors of the jugulotympanic, intravagal paraganglia in decision order. Those of laryngeal, nasal and nasopharyngeal and orbital paraganglia are rarely developed.
The majority of laryngeal paraganglioma are noninvasive, vascular, supraglottic, submucosal mass. But obscure finding and initial histologic misdiagnosis often lead to incorrect diagnosis and delay appropriate treatment.
The incidence of such errors should decrease with increasing knowledge of the lesion and availability of immunohistochemistry and electron microscopy.
Recently the authors experienced a case of laryngeal paraganglioma and are reporting the case with review of literature.
