A removed membranous material, which encased the cardiac pacemaker is seen (A ). Histologically, a foreign body with a thickness of 0.1 mm is embedded in a dense fibrous stroma (B ). The material and calcification are indicated by arrows and arrowheads, respectively. The higher magnification image of the material shows a laminar structure indicated by asterisks. Scale bar in A, B, and C is 1 cm, 0.1 mm, and 0.1 mm, respectively.
