Resumen

BRAVO C, Gustavo et al. Parotid hybrid tumor. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2012, vol.72, n.3, pp.228-290. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162012000300012.

Tumors of the salivary glands represent 33%-10% of head and neck neoplasms. The most common location is the parotid gland, accounting for 50%-85% of the cases, with 20%-30% of them being malignant. The following are known to be indicative of a malignant tumor: fast growing, painless mass, associated facial paralysis and lymphadenopathy. Most parotid neoplasm derive from a single histological type but eventually the development of more than one type on the same gland can occur. This paper presents a case of a parotid neoplasm with two different histological tumors, with uncharacteristic clinical presentation. The patient presented initially with ear pain and otorrhoea, in the clinical examination highlighted an external auditory canal tumor. The complementary study revealed a parotid neoplasm and a total resection of the gland was performed. The biopsy revealed an adenoid-cystic carcinoma with differentiated basaloid areas. Adjuvant radio-chemotherapy was administered, and the imaging control with PET-CT showed no evidence of recurrence or dissemination of the tumor.

Palabras clave : Parotid hybrid cancer; hybrid salivary gland tumor.
