PURPOSE: To report a case with rapid regression of scleral melting associated with tumor necrosis factor-α (TNF-α) in a surgically induced necrotizing scleritis (SINS) patient treated with local steroid therapy.
CASE PRESENTATION: An 85-year-old male patient presented with conjunctival tumor in his right eye. Complete resection of the tumor lesion and conjunctival re-construction were performed. Local steroid drops were administered until 1 month after surgery, and a good clinical course was achieved. However, after stopping the local steroid, scleral melting to the uvea occurred on the center of the tumor-resected sclera. After diagnosing SINS, we immediately restarted his local steroid. After 2 weeks, there was a complete and rapid regression of the scleral melting. Following this episode, only local steroid therapy was continued for the treatment of SINS, with no recurrence observed after 6 months. Histopathological analysis revealed the infiltration of inflammatory cells during the acute phase, with TNF-α immune reactivity observed in the center of the melting site near the resected conjunctiva.
CONCLUSION: We speculate that the observed changes were associated with the TNF-α that was present during the pathological state of SINS. Local steroid therapy may play a key role in the local immune balance in SINS.
