desc11 = 'Case 1 - Figure 1
Scanning magnification photomicrograph of the H&E stained section of lung showing thick-walled pulmonary arteries and a bone marrow embolus (likely an agonal event) ';
desc12 = 'Case 1 - Figure 2
Closer inspection of the arteries shows medial thickening ';
desc13 = 'Case 1 - Figure 3
Concentric luminal compromise ';
desc14 = 'Case 1 - Figure 4
Nicely accentuated by an elastic tissue stain (EVG) ';
desc15 = 'Case 1 - Figure 5
Eccentric subendothelial lesions are also highlighted by the EVG stain ';
desc16 = 'Case 1 - Figure 6
Two plexiform lesions (PLX), each present adjacent to a pulmonary artery branch, are present in this photomicrograph. Dilated blood-filled thin-walled vascular spaces--so called angiomatoid lesions (dark arrows), can be seen surrounding the plexiform lesion at the top of the photograph ';
desc17 = 'Case 1 - Figure 7
A transverse section through a plexiform lesion nicely illustrates the relationship of these complex endovascular lesions to the parent artery ';
desc18 = 'Case 1 - Figure 8
Note the thin muscle layer (sm) present above and below the lesion, and the apparent focal nature of the process. The EVG stain outlines an attenuated elastica ';
desc19 = 'Case 1 - Figure 9
The EVG stain highlights the relationship of the angiomatoid and plexiform lesions to the parent artery. Note the relative absence of a well-defined elastic lamina in these lesions ';
desc1a = 'Case 1 - Figure 10
The triumvirate of pulmonary artery (PA) branch, plexiform lesion (PLX), and angiomatoid (dilatation) lesion (arrows) is well-illustrated in this photomicrograph ';
desc21 = 'Case 2 - Figure 1
Pulmonary vein showing almost completely obstructive intimal fibrosis ';
desc22 = 'Case 2 - Figure 2
Elastic stain highlights almost complete venous occlusion and interstitial thickening around the vein ';
desc23 = 'Case 2 - Figure 3
Elastic stain with an arterialized pulmonary vein on the right side showing obstructive intimal fibrosis and on the left hand side fibrous thickening of the interlobular septum ';
desc24 = 'Case 2 - Figure 4
Elastic stain of pulmonary vein showing arterialization with the medial coat of smooth muscle bounded by internal and external elastic laminae ';
desc25 = 'Case 2 - Figure 5
Area of peripheral interstitial fibrosis ';
desc31 = 'Case 3 - Figure 1
H&E, low magnification ';
desc32 = 'Case 3 - Figure 2
H&E, intermediate magnification ';
desc33 = 'Case 3 - Figure 3
H&E, polarized light ';
desc34 = 'Case 3 - Figure 4
Mucicarmine stain (left panel), Movat stain (right panel)(40X magnification, both panels) ';
desc35 = 'Case 3 - Figure 5
Congo red stain, intermediate magnification ';
desc36 = 'Case 3 - Figure 6
Gomorri methenamine silver stain (left panel), Movat stain (right panel) 40X magnification, both panels) ';
desc41 = 'Case 4 - Figure 1
Low power of bronchus with anastomosing vascular spaces ';
desc42 = 'Case 4 - Figure 2
Medium power of bronchial wall and adjacent lung with spongy vascularity ';
desc43 = 'Case 4 - Figure 3
Medium power highlighting compact spindle cells along spaces ';
desc44 = 'Case 4 - Figure 4
Compact spindle cells with bland elongate nuclei ';
desc45 = 'Case 4 - Figure 5
Actin stain ';
desc51 = 'Case 5 - Figure 1
CT scan from current admission showing areas of consolidation on a background of ground glass infiltrates ';
desc52 = 'Case 5 - Figure 2
Low power view of surgical lung biopsy. Note diffuse interstitial fibrosis and evidence of chronic hemorrhage ';
desc53 = 'Case 5 - Figure 3
Higher power view of surgical lung biopsy. Hemosiderin deposition is better seen ';
desc54 = 'Case 5 - Figure 4
Iron and calcium-encrusted elastica in a small pulmonary vessel. This finding is typical of chronic hemorrhage ';
desc55 = 'Case 5 - Figure 5
Higher power view of another vessel showing the encrusted elastica ';
