The accessory submandibular gland is a rare anatomic variant and the incidence of pathology reported within an accessory submandibular gland is even rarer. This report describes the case of a 22-year-old woman who presented with a slowly enlarging mass in the submandibular triangle, which on ultrasound examination suggested that it was close to, but not arising from, the submandibular gland. Fine-needle aspiration cytology was consistent with a pleomorphic adenoma. At surgery, the tumor was found to be entirely separate from the submandibular gland. This case presents an extremely rare occurrence of an accessory submandibular gland and, to the authors' knowledge, is the first report of a pleomorphic adenoma occurring within an accessory submandibular gland.

UI	MeSH Term	Description	Entries
D008949	Adenoma, Pleomorphic	A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.

D013363	Submandibular Gland	One of two salivary glands in the neck, located in the space bound by the two bellies of the digastric muscle and the angle of the mandible. It discharges through the submandibular duct. The secretory units are predominantly serous although a few mucous alveoli, some with serous demilunes, occur.
