Lung metastases from cutaneous adenoid cystic carcinoma 23 years after initial treatment

Abstract

Cutaneous adenoid cystic carcinoma (CACC) is an extremely rare neoplasm of head and neck region, and is characterized by propensity for local recurrence and perineural invasion. Late distant metastases occur usually to lungs. Although patients with lung metastases from CACC cannot be cured, long-term survival may be possible due to its slow-growing malignancy. We report a case of a 69-year-old female with lung metastases from CACC 23 years after initial surgery of scalp nodule.
