Summary

Immune checkpoint inhibitors have become standard of care in metastatic malignant melanoma management. Despite superior effectiveness to chemotherapy, significant immune-related adverse events (irAE) may occur, particularly if used in combination. Gastrointestinal irAEs were reported with different patterns of involvement. Here, we report the case of a patient who had ileal perforation as a complication of terminal ileitis, without colitis, induced by combination immune checkpoint blockade.
