Аннотация
INTRODUCTION: Squamous cell carcinoma ex-pleomorphic adenoma (CXAP) is a malignant and rare mixed tumor. We report a new case.
OBSERVATION: A seventy-year-old woman consulted for a mass in the left hemi-face having evolved over the last 20years. The physical examination revealed a hard and large tumor invading all the palate. Computed tomography revealed a heterogeneous 8.5cm long maxillary mass. The diagnosis of CXAP was made on a biopsy. A histological study confirmed the diagnosis after surgical resection of the tumor, specifying its noninvasive character.
DISCUSSION: CXAP is generally located in the parotid gland; it is very rarely located in the palate. The degenerated epithelial component generally corresponds to an adenocarcinoma or an undifferentiated carcinoma; squamous-cell carcinoma is more rarely reported. The prognosis is excellent for the micro and noninvasive types. Surgery remains the treatment of choice.
