title: Charcot-Leyden crystals within a periapical lesion.
abstract: Transmission electron microscopy revealed the presence of Charcot-Leyden crystals within a periapical lesion, which was assessed histopathologically as consistent with a periapical granuloma that failed to resolve after conventional endodontic treatment. This paper presents the clinical, radiographic, histological, and ultrastructural findings of this case and discusses their potential clinical significance.
