ABSTRACT

Resumen Los tumores malignos de glándulas salivales (TMGS) constituyen un grupo infrecuente de cánceres de una gran variedad histológica. Dentro de las neoplasias de estirpe epitelial encontramos al carcinoma de células acinares (CCA), que representa entre un 6%-10% de todos los TMGS. No posee patrones clínicos ni radiológicos específicos, pero comparte características comunes con otros TMGS que serán discutidas a lo largo del reporte. Cabe destacar que en términos generales es un cáncer de bajo grado y poco recidivante, por lo que un tratamiento oportuno y un seguimiento estricto mejoran el pronóstico para este tipo de pacientes. Su diagnóstico se establece con evidencia histopatológica que confirme la presencia de diferenciación epitelial de tipo acinar. El tratamiento consiste en la exéresis tumoral con márgenes libres por parotidectomía suprafacial o total, asociado a vaciamiento cervical si se detecta compromiso nodal. Adicionalmente, se debe sugerir terapia adyuvante ante la presencia de un factor de mal pronóstico. Se presenta un caso y se realiza revisión de literatura.


Abstract Malignant salivary gland tumors (TMGS) constitute an infrequent group of cancers of a wide histological variety. Within the epithelial lineage neoplasms, we find acinar cell carcinoma that represent between 6%-10% of all TMGS. It does not have specific clinical or radiological patterns, but it shares common characteristics with other TMGS that will be discussed throughout the report. It should be noted that in general terms it is a low-grade cancer with low recurrence rates, so timely treatment and strict follow-up improve the prognosis for this type of patient. Its diagnosis is established with histopathological evidence that confirms the presence of acinar-type epithelial differentiation. Treatment consists of tumor excision with free margins by suprafacial or total parotidectomy, associated with cervical lymph node dissection if nodal locoregional metastasis is detected. Additionally, adjuvant therapy should be suggested in the presence of a poor prognostic factor. A case is presented and a literature review is carried out.
