Figure 1. Distribution of granulomas in pulmonary sarcoidosis.

Figure 1

Sarcoidosis granulomas are found in a lymphatic distribution, including surrounding the bronchovascular bundle (circled area); the interlobular septae which also contain the pulmonary veins (adjacent to the line); and the subpleural area (arrow). Because of this anatomic orientation, granulomatous inflammation frequently encroaches on the vascular structures, even in the absence of overt fibrosis or vascular wall inflammation (Hematoxylin and eosin).
