A Case of Resected Solitary Pulmonary Metastasis and Local Recurrence 10 Years after the Removal of Submandibular Adenoid Cystic Carcinoma

Abstract

A 50-year-old man who had undergone resection of both a solitary pulmonary metastasis and a local recurrence 10 years after the resection of adenoid cystic carcinoma of the right submandibular gland was reported.
In this case, because of its characteristic histological aspect, the resected lung tumor was suspected to be metastatic and the primary site was easily determined. This case shows that when the histological aspect of a lung tumor is uncommon, if it is a solitary tumor, a metastatic tumor should be suspected first and examination of the primary site should be performed quickly.
