PAROTID GLAND MALIGNANCIES - DIAGNOSTIC QUERIES IN RARE SITUATIONS: REPORT OF TWO CASES
Abstract:
Parotid malignancies are a heterogeneous group of diseases that include 23 entities, all of
epithelial origins. Non-epithelial tumours are rare, representing about 2-5% of all salivary gland
tumours. Primary lymphatic tumours of the parotid are even rarer. The clinical appearance usually
includes a variable history of slow growing painless, nodular mass that enlarges rapidly. The
cytological evaluation should identify whether the parotid lesion is inflammatory or neoplastic, and if it
is malignant or benign. On diagnosis of a salivary gland tumour, it is important to correctly classify the
tumour especially if malignant in order to apply the correct treatment. There are presented two cases of
rare malignant entities with lymphoid component located on parotid gland which presented difficulties
in preoperative diagnosis.
