A malignant tumor that occurs in the tongue is histologically squamous cell carcinoma in many cases, and a salivary gland malignant tumor originating from the lingual gland, especially the anterior lingual salivary gland, is very rare. We report a case of adenocarcinoma, not otherwise specified (NOS) occurring from the anterior lingual salivary gland. The patient was a 52-year-old woman with a spherical, elastic hard and painless mass in the right side of the submucosa of the tongue. The results of diagnostic imaging indicated the possibility of a tumor derived from a gland. Since it was not possible to determine whether the mass was benign or malignant, an incisional biopsy was performed. However, the pathological diagnosis was a malignant epithelial tumor derived from a minor salivary gland, which did not lead to a definitive diagnosis. Following a clinical diagnosis of tongue carcinoma (cT1N0M0), the tumor was surgically resected under general anesthesia. The histological features and immunohistochemical profiles did not match those of known epithelial salivary gland carcinomas. Consequently, the resected tumor was pathologically diagnosed as adenocarcinoma, NOS. There was no recurrence for 3 years after the operation.
