Adenoid cystic carcinoma metastatic to the lung. Report of a case diagnosed by fine needle aspiration biopsy cytology.
Cytologic examination of a fine needle aspiration (FNA) biopsy specimen served to diagnose a lung metastasis in a patient with an adenoid cystic carcinoma primary in a minor salivary gland of the hard palate. The aspiration cytologic features of the metastatic adenoid cystic carcinoma were similar to those of primary adenoid cystic carcinoma, including uniform tumor cells with scant cytoplasm surrounding transparent, mucoid spherical bodies. FNA biopsy cytologic diagnosis of metastatic adenoid cystic carcinoma is accurate, particularly if mucoid spherical bodies are present.
