Granulomatous angiitis in a patient with sarcoidosis-associated pulmonary hypertension

This graphic depicts granulomatous angiitis in a patient with SAPH. Chest imaging revealed very little pulmonary parenchymal disease (A). Histopathology showed a normal veins (B, arrow), arteries (C, arrow), and bronchi (C, arrowhead); and occasional nonnecrotizing granuloma formation in alveolar spaces (D, arrows). However, extensive nonnecrotizing granulomatous inflammation around veins (E) and arteries (F) was sufficient evidence to explain PH.
