A rare case of multiple primary benign neoplasm of parotid gland: oncocytoma and adenolimphoma
Journal Title: Otolaryngologia Polska - Year 2009, Vol 63, Issue 7
Abstract
Aim of the work: The authors present unusually rare case primary multiple synchronicus benign tumor of the ipsilateral parotid gland: oncocytoma and Warthin’s tumor, which is rare among occasionally occurred multiple tumors with different histology in the salivary glands. Material and method: A 71-year-old man presented with the tumor in the right parotid gland. We performed excision of the superficial lobe of the parotid gland. The preoperative ultrasonography and macroscopic analysis of the removed parotid gland tissue revealed only one tumor recognised histopathologically as adenolimphoma, but upon histopathological examination Warthin’s tumor proved to coexist with oncocytoma. Results and conclusions: In the ultrasonography examination some salivary glands tumors may not be recognised. The histopathological examination is the ultimate method in recognising tumors, which are not detected in the preoperative diagnosis. The superficial parotidectomy protects from the recrudescence of the superficial lobe of the parotid gland tumors. The coexistence of the oncocytoma and Warthin’s in one parotid gland is extremely rare. Only a few cases were described in the English literature and in the available Polish literature there is none of such reports.
