RESUMO
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. Total parotidectomy conservative of facial nerve was recommended, without regional lymphadenectomy. Patient remains, one year later, asymptomatic and free of disease.

Presentamos el caso de un varón de 43 años de edad que consulta por una tumoración preauricular derecha dolorosa a la palpación que, según refiere, tiene más de tres años de evolución. Se realiza punción aspiración con aguja fina que informa de compatible con carcinoma de células acinares, por lo que se realiza cuantificación de ADN por citometría de imagen. Los parámetros biológicos estudiados (ploidía, fase S, células por encima de 5c) indican que se trata de una lesión de bajo grado de malignidad.Con estos datos se practica parotidectomía total conservadora del facial, sin vaciamiento ganglionar. El paciente se encuentra, un año después, asintomático y libre de signos tumorales residuales
