However, from the pathology standpoint, 3 distinct pathologic patterns might be found in those patients: plexogenic
pulmonary arteriopathy, recurrent pulmonary thromboembolic disease, and pulmonary veno-occlusive disease (PVOD).
Additional findings at autopsy included cardiomegaly at 720 gm (234-390 gm), bilateral pulmonary edema containing hemosiderin laden macrophages, congestive hepatosplenomegaly and plexogenic
arteriopathy on pulmonary microscopic examination.
angiopathy in pulmonary intralobar sequestrations pathogenetic mechanisms.
Thrombotic lesions in primary plexogenic
Membranoproliferative glomerulonephritis and plexogenic

56) The hallmark histopathologic lesion is plexogenic
7cm) and microscopic plexogenic
arteriopathy, low grade, consistent with pulmonary hypertension within the intrapulmonary vasculature.
arteriopathy associated with pulmonary vasculitis in systemic lupus erythematosus.
These cells, infected by HIV-1, may release specific cytokines (eg, endothelin-1) that by vasoconstriction of the endothelial cells and proliferation of the smooth muscle cells cause the classic plexogenic
The microscopic features ascribed to PH can broadly be called plexogenic
11] In a prospective study  of 507 patients with portal hypertension, prevalence of pulmonary hypertension was 2%, with the majority of patients having plexogenic
pulmonary arteriopathy on biopsy or autopsy.
3] Histopathologic examination of 36 patients undergoing heart-lung transplantation with plexogenic
pulmonary arteriopathy revealed cholesterol granulomas in 9 cases.
