“…Another illustrative case of bilateral intratarsal ossification associated with immunoglobulin light chain amyloid displayed prominent antecedent dystrophic calcification adjacent to the bone. 4 Given the focal longstanding nature of the illustrated eyelid lesion, it is reasonable to assume a precursor either in the form of a chalazion, in which ossification has been previously described, 1,5 or an intratarsal keratinous cyst, suggested by the concentric lamellae within the histopathology. While the lamellae could not be characterized by immunohistochemistry, it is possible that loss of antigenicity occurred over time.…”
