Pulmonary Pathologic Manifestations of Anti-Alanyl-tRNA Synthetase (Anti-PL-12)-Related Inflammatory Myopathy.

CONCLUSIONS: - Lung disease is often the first manifestation of anti-PL-12 ARS. There are no pathognomonic histopathologic features to distinguish anti-PL-12 ARS-related lung disease from idiopathic variants of diffuse interstitial lung disease. Increased inflammation, lymphoid aggregates, and nonspecific interstitial pneumonia-like areas in a biopsy, as well as clinical features of mechanic's hands, Raynaud phenomenon, arthritis, and fever, should prompt pathologists to suggest involvement by ARS.
