Light microscopy, magnification 200x
Patients with pulmonary hypertension develop complex vascular lesions that block their small pulmonary arteries. This photomicrograph of a pentachrome-stained of a lung section from a patient with pulmonary hypertension shows a pulmonary artery that is almost completely closed. The multiple colors indicate the complexity and varying cellular constituents of this lesion.
