Well-differentiated fetal adenocarcinoma of the lung: early-phase sequential high-resolution computed tomographic findings.

Abstract Well-differentiated fetal adenocarcinoma is a rare primary adenocarcinoma originating in the lung. We present an early phase case that was followed up for 2 years with chest roentgens and high-resolution computed tomography. Multicentric origin was suspected in the sequential high-resolution computed tomography study findings.
