Figure 2: (A-C) Periapical granuloma. Intraoral periapical radiograph (A) shows a well-circumscribed radiolucent periapical lesion (arrow) without a sclerotic border, measuring less than 1 cm in size. USG with color Doppler and power Doppler shows a poorly defined hypoechoic lesion (arrow) exhibiting a rich vascular supply on color and power Doppler examinations. H&E stained section (C) shows fibrocellular connective tissue stroma (arrow) consisting of chronic inflammatory cell infiltrate (mainly lymphocytes and plasma cells) and endothelium-lined blood capillaries with red blood cells, fibroblasts, and collagen fibers
