case_images: Computed and magnetic tomography, with 1.25 mm thickness cuts in the transverse plane and with image reconstruction cuts of 1.25 and 2.5 mm in coronal and sagittal planes, respectively, revealed a lesion of 1.64 cm x 4.8 cm in dimensions which occupied the right buccal space, originating from the right major zygomaticus muscle, and extending to the right anterior part of the parotid gland (Figures 1 and 2).

case_images: FNA biopsy was performed, retrieving numerous lymphocytes and nonspecific atypical cells, and was characterized as nondiagnostic (Figure 3). Permanent histology described a solid white/brown ulcerated neoplastic mass with a maximum diameter of 5.3 cm (Figure 3).
