a Neck ultrasonography of a 55-year-old male patient showed a right inferior parathyroid lesion with hypoechoic and hyperechoic components. b Low-power photomicrograph (×50, H&E stain) shows a section of parathyroid adenoma with multiple discrete granulomas within (arrows). c High-power photomicrograph (×200, H&E stain) shows a well-circumscribed epithelioid granuloma surrounded by lymphocytes amidst oncocytic cells of the parathyroid adenoma
