Adenoma pleomorfo palatino. Caso clínico, revisión de la literatura y puesta al día

Resumo

Pleomorphic adenoma is the most frequent benign tumour of the salivary glands, most frequently developing in the parotid. The clinical manifestations vary depending on the salivary glands involved, as well as the degree of presentation, size, evolution time and its evolutionary growth. It is more prevalent in women in the third and sixth decade of life, and is infrequent in children. It has a slow and continuous growth and histologically it is very variable, consisting of epithelial elements and myoepithelial cells, coated or not by a pseudocapsule that can be pierced by extensions of the tumour. Its early diagnosis through imaging tests and histological study is very important due to its possible complications, since despite being a benign tumour, it can become malignant on occasion. The treatment consists of the surgical excision of the tumour. There is a discussion of a case of a 25 years old male, who came for a consultation due to the presence of an asymptomatic tumour in the palate which had been developing for 4 years. After the complete removal of the lesion, the histological study confirmed the diagnosis of pleomorphic adenoma. The evolution, treatment, immediate complications and the evolution of the case over 24 months are discussed. The current clinical-pathological and therapeutic-focussed thinking about pleomorphic adenoma is reviewed, with a special emphasis on its intraoral location.
