N2 - PURPOSE: To report a case of conjunctival epithelial ingrowth after penetrating keratoplasty. METHODS: A 57-year-old woman with herpetic corneal keratitis, endotheliitis, and bullous keratopathy underwent penetrating keratoplasty (PKP) and secondary cataract surgery. One month after cataract surgery, an epithelial ingrowth was observed at the 5 o'clock donor host junction. Ingrowth extended into the anterior chamber and along the iris surface by 9 months. Another PKP was performed, and the excised graft was submitted for histopathology. RESULTS: The graft showed CK13-positive and CK3-negative cells lining the endothelial surface, indicating the conjunctival origin of ingrown epithelium. Ten months postoperatively, no recurrence of ingrowth was observed. CONCLUSIONS: We experienced a rare case of conjunctival epithelial ingrowth after penetrating keratoplasty. There was no recurrence of the ingrowth after surgical removal, and the conjunctival origin may explain the relatively benign course of the complication.
