Secretory carcinoma was added to the new WHO classification of salivary gland tumors revised in 2017. The clinical behavior of such tumors is not completely understood because there are few reports by otolaryngologists to date. We report a case of secretory carcinoma of the salivary gland. The patient was a 61-year-old man who underwent surgical excision with a diagnosis of malignant tumor of the left parotid gland （cT3N0M0）, and histopathological examination indicated secretory carcinoma. Two years postoperatively, lung metastasis was observed, but we decided to follow up at the request of the patient. Although the mass has grown slowly, he has survived with the tumor for five years. Secretory carcinoma is thought to follow a clinical course of low-grade carcinoma, but there have been reports of a poor prognosis in some cases of distant metastasis, and a sudden exacerbation in other cases, so careful follow-up is important.
