Mucinous adenocarcinoma (MAC) refers to a malignant neoplasm that belongs to a subtype of adenocarcinoma which produces mucin. The World Health Organization has classified MAC as a tumor of salivary gland origin and it is extremely rare. Therefore, its characteristics are not well-known. This study reports a case of MAC of minor salivary gland origin, which occurred in the oral commissure of an 82-year-old female patient, and a systematic review on existing cases of MAC of salivary origin. Based on the study’s findings, it is safe to assume that the occurrence of lymph node metastasis is an important factor in determining the prognosis of patients with MAC.
