Abstract:

Laryngeal cystadenoma (other terminological names; oncocytic cystadenoma, papillary cystadenoma, oncocytic adenoma) is a rare benign, slow growing, predominantly composed of oncocytes and its epithelial component is similar to Warthin tumors (papillary cystadenoma lymphomatosum) seen in the major salivary glands. We aimed to present the rare case of laryngeal oncocytic cystadenoma in the same case by examining the relationship between the accompanying parotid gland's Warthin tumor. Laryngeal oncocytic cysts are histologically similar to Warthin (papillary cystadenoma lymphomatosum) tumor, but differentiate due to the fact that it does not have a two-fold structure consisting of oncocyte and lymphoid stroma is similar to that. Magnetic resonance imaging is the gold standard method in diagnosis of complex lesions. The optimal treatment is endoscopic or open laryngeal surgical excision. Malignant transformation of the lesion is not clear, close monitoring of the operated area is essential.
