[Multiple lung metastases from cutaneous adenoid cystic carcinoma resected 21 years before]

A 79-year-old woman whose cutaneous tumor had been resected 21 years and 12 years (local recurrence)before pathologically confirmed as primary cutaneous adenoid cystic carcinoma (ACC), was referred to our hospital for the abnormal shadow on chest X-ray. Chest computed tomography (CT)revealed 3 nodules in the peripheral field of both lungs, which were diagnosed by echo-guided needle biopsy as metastasis from the cutaneous ACC, and were completely resected at 5 months intervals. Any recurrences have not been detected for 2 years after the lung resection. In primary cutaneous ACC, not only complete resection with adequate margin but long-term follow up is recommended.
