DNA quantification as prognostic factor in a case of acinar cell carcinoma of the parotid gland, diagnosed by FNA.

Hereby we present a case of a 43-years-old male who complained of a three years history preauricular painful mass. Fine needle aspiration cytology was performed, diagnosing of compatible with acinar cell carcinoma, thus DNA quantification by image cytometry was carried out. Biological parameters studied (ploidy, S-phase, 5-c exceeding rate) showed that it is a low grade of malignancy lesion.
