Adenoid Cystic Carcinoma of the Palate: Report Case

Abstract

Adenoid cystic carcinoma is a rare tumor, accounting for approximately 5–10% of all salivary gland neoplasms. It is a tumor which develops in 50 to 60% of cases on the minor salivary glands which are disseminated on the cheek; the lips; the palace; it is characterized by slow growth with a long-term natural evolution, quite aggressive locally, which has a tendency to local recurrence and even distant metastases (the first metastatic site of which is the lung). There are three subtypes that can exist in isolation or coexist together which are: solid; cribriform and tubular. The solid type has a poor prognosis unlike the cribriform type which has an intermediate prognosis and the tubular type which has the best prognosis. The treatment of choice remains surgical, often associated with adjuvant radiotherapy depending on the stage of progression (stage III and IV). It is almost not chemosensitive. It is a tenacious tumor and the survival rate at 05 years is 70%; after 10 years 50% and after 20 years 25%. We present a case of a 53-year-old patient; without particular pathological history, which presents an adenoid cystic carcinoma in its solid form locally advanced non-metastatic revealed by a budding mass of the hard and soft palate. Given the inoperability of the tumor; the patient was referred for Radiotherapy.
