ABSTRACT

Paciente masculino de 81 años de edad que acudió a consulta con un cirujano dentista por presentar una lesión nodular, asintomática, firme y móvil en el labio superior del lado derecho. El sujeto refi rió tener la lesión desde la infancia, pero notó crecimiento lento en el último año. El diagnóstico clínico indicaba un adenoma pleomorfo, por lo que el individuo se sometió a biopsia escisional bajo anestesia local. El espécimen se envió a estudio histopatológico. La evolución del paciente fue satisfactoria, sin reincidencia de la lesión. El examen microscópico reveló la presencia de una neoplasia bien delimitada constituida pormúltiples estructuras ductales pequeñas en la dermis. Estos ductos se encontraban revestidos por dos hileras de células epiteliales planas y contenían cantidades variables de material amorfo en la luz. El estroma presentaba diferenciación condroide.


An 81-year-old male patient consulted a dental surgeon due to his presenting a fi rm, mobile, asymptomatic nodular lesion on the upper lip. The patient stated that he had had the mass since childhood but that it had grown slowly over the course of the previous year. The clinical diagnosis was pleomorphic adenoma, for which reason the patient underwent an excisional biopsy under local anesthesia. The specimen was sent for histopathological examination. The patient’s progress was satisfactory and there was no recurrence of the lesion. Micro-scopic examination revealed the presence of a well-defi ned neoplasm consisting of multiple small ductal structures located in the dermis. These ducts were lined with two rows of fl attened epithelial cells and contained varying amounts of amorphous material in the lumen. The stroma exhibited chondroid differentiation.
