Lung metastases of adenoid cystic carcinoma mimicking broncho alveolar carcinoma growth pattern

Abstract

Adenoid cystic carcinoma (ACC) is one of the most common salivary gland malignancy. Loco regional and distant metastases are common in 40–60%, even after a short disease free interval. Most frequently, ACC metastasize to the lung, bone, liver and cerebrum with solid pattern. We present a case of bilateral lung metastases in a patient with ACC and active tuberculosis mimicking bronchoalveolar carcinoma ground glass opacities.
