Figure 1From: Capsular synovial metaplasia mimicking silicone leak of a breast prosthesis: a case report Capsular synovial metaplasia. Sections from the cavity show the surface of the capsule lined by fibrohistiocytic cells. The nuclei of these cells are basally oriented and are polarized perpendicular to the cavity surface. The interface between the capsule and implant space is smooth. The overall features are indicative of synovial metaplasia.Back to article page
