Basal cell adenoma of the sublingual gland.
Salivary gland tumors constitute about 3% to 4% of all head and neck neoplasms. Approximately 80% originate in the parotid gland, and they rarely present in the sublingual gland; however, a disproportionately large majority of sublingual gland tumors are malignant. Basal cell adenoma is a benign epithelial salivary gland tumor that appears to have unique histologic characteristics, different from those of mixed tumors, and has a predilection for development in the parotid and minor salivary glands. No case has ever been reported as arising from the sublingual gland in the otolaryngology literature. We report here a case of a middle-aged woman with basal cell adenoma of the sublingual gland. The clinical presentation, pathological features, differential diagnosis, and treatment options for this relatively rare tumor are discussed.
