RESUMEN
El mioepitelioma de glándula salivar es una neoplasia benigna poco frecuente, que afecta principalmente a la parótida (40 %) y que muestra exclusivamente diferenciación mioepitelial. Histológicamente, exhibe variables patrones arquitecturales y diferentes tipos celulares, que pueden ser dominantes o entremezclarse en diferentes proporciones, lo que condiciona una marcada variabilidad morfológica en el material obtenido por PAAF y con frecuencia su incorrecta interpretación diagnóstica. Aportamos un caso de mioepitelioma parotídeo, diagnosticado inicialmente como maligno en la PAAF, con estudio histológico e inmunohistoquímico
ABSTRACT
Salivary gland myoepithelioma is a benign rare neoplasm whose main location is the parotid gland (40 %) and displays an exclusive myoepithelial differentation. Histologically it shows several and variable architectural patterns and cellular types that can be dominant or mixed in diverse proportions. This leads to a marked morphological variability in the material obtained by FNAB and not unfrequently to a wrong diagnostic interpretation. We report the case of a parotid lump, initially diagnosed as a malignant neoplasm by FNAB. Later, the tumor ,was correctly diagnosed as myoepithelioma after histological and inmunohistochemical examination
