Abstract

BACKGROUND:

The aim of the study was to examine whether pleomorphic adenoma of salivary glands can occur on the basis of constitutional BRCA-1 mutations.

MATERIALS AND METHODS:

Two hundred and sixty-eight patients affected by mixed tumour of salivary glands were examined for occurrence of three BRCA-1 mutations dominating in Poland.

RESULTS:

BRCA-1 mutation was detected in only one of the patients, a female affected by breast cancer and pleomorphic adenoma of parotid gland. Parotid gland tumour showed clinical and histopathological features of typical pleomorphic adenoma with no morphological features of high-grade malignancy, which are characteristic of BRCA-1-dependent tumours.

CONCLUSION:

Considering the low frequency of BRCA-1 mutation in the examined group and also the absence of features characterizing BRCA-1-dependent tumours in the only BRCA-1-positive case, pleomorphic adenoma of salivary glands should not be recognized as a BRCA-1 dependent tumour.
