title: [The synchroneous tumors of different histopathology in the parotid salivary gland].
abstract: Ipsilateral salivary gland tumors of different histological types are very rare. Out of 196 parotidectomies performed (from 03. 2001 to 12. 2005), in 6 (3.06%) cases synchronous tumors of different type has been found in pathologic specimens. In 5 cases pleomorphic adenoma was one of synchronous tumor--in 2 cases with adenocarcinoma and in single cases with salivary duct carcinoma, adenolymphoma, and myoepithelioma. In one case, the adenolymphoma was synchronous with carcinoma planoepitheliale metastaticum from the primary in the skin post auricular area (late metastasis). Following the review of literature concerning the problem, two concepts has been critically discussed--the real synchronous occurrence of two different tumors, and transformation of benign tumor of salivary neoplasm to its malignant form.
