Abstract:
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.

Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
