Capsular tissue around a latex elastic with numerous macrophages (m) and some neutrophils at 3 days. Fiber formation (f) was greater at 7, 14, and 21 days than at 3 days, and the fibers were organized in the form of a fibrous capsule. The greater thickness at 3 days refers to higher accumulation of cells and edema, which were significantly reduced at 7, 14, and 21 days (HE; 40× magnification).
