Basal cell adenoma (BCA) is a rare benign epithelial tumor of the salivary glands, accounting for 1 to 3% of all parotid tumors. We report the case of a 65-year-old woman with no significant medical history, presenting with a slowly growing right parotid swelling that had been evolving for one year. Ultrasound revealed a well-defined hypoechoic homogeneous nodule measuring 10 x 15 mm with peripheral Doppler vascularization. MRI showed an encapsulated nodule of the superficial lobe of the right parotid gland, with intermediate heterogeneous T2 signal, progressive gadolinium enhancement of type A, and no diffusion restriction, measuring 10 x 12 x 8 mm. The patient underwent superficial parotidectomy with facial nerve preservation and clear resection margins. Histopathological examination revealed an encapsulated tubulo-trabecular proliferation with round to oval basaloid cells, eosinophilic cytoplasm, fine chromatin, rare mitoses, and no necrosis. Immunohistochemistry showed positivity for p63 and LEF1 in basal cells, CD117 in luminal cells, focal beta-catenin expression, and negativity for mammaglobin. The postoperative course was marked by a transient buccal branch paresis, which resolved within three months with physiotherapy. At two years of follow-up, no recurrence was observed.
