El tumor benigno más frecuente de las glándulas salivales mayores es el adenoma pleomorfo. Además de las glándulas salivales mayores, también puede ocurrir en las glándulas salivales del paladar duro y blando. Raros casos se han reportado en la nasofaringe, orofaringe, hipofaringe y laringe. Adenomas pleomorfos intranasales son muy infrecuentes y pueden ser mal diagnosticados debido a que tienen mayor celularidad mioepitelial y poco estroma mixoide, en comparación con los que se localizan en otros lugares. Presentamos dos raros casos de adenomas pleomorfos del septum nasal y analizamos los hallazgos patológicos y el manejo clínico. Se revisa la literatura en relación al tema.Palabras clave: Adenoma pleomorfo, septum nasal, glándula salival.
ABSTRACTThe most common benign tumor of major salivary glands is the pleomorphic adenoma. In addition to the major salivary glands may also occur in the salivary glands of hard and soft palate. Rare cases have been reported in the nasopharynx, oropharynx, hypopharynx and larynx. Intranasal pleomorphic adenomas are very rare and can be misdiagnosed because they have greater myoepithelial cellularity and little myxoid stroma, compared with those located elsewhere. We report two rare cases of pleomorphic adenomas of the nasal septum and analyze the pathological findings and clinical management. We review the literature on the subject.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
