Primary cutaneous adenoid cystic carcinoma (PCACC) is extremely rare, and although distant metastasis has been reported, to date, there are no reports regarding metastasis to the nasal septum. We report a rare case of PCACC that metastasized to the nasal septum 17 years after the first surgery in a 59-year-old woman. She initially presented with a mass under the skin of her left mammary papilla. After a biopsy revealed the presence of an adenoid cystic carcinoma, the tumor was excised and definitively diagnosed as a PCACC. Five years after surgery, the patient presented with left lung metastasis and underwent a partial resection of the left lung. However, 8 years after this procedure, the patient had to undergo a partial resection of the right lung because of right lung metastasis. Four years thereafter, the patient presented with nasal septal metastasis. The tumor was excised successfully using a combined technique integrating intranasal and extranasal approaches. The patient is currently undergoing regular follow-up tests. Thus, in such cases, lifelong follow-up is necessary while checking for both distant metastasis and instances of local recurrence.
