This report describes a rare case of Stevens-Johnson syndrome (SJS) induced by pembrolizumab in a patient with advanced lung squamous cell carcinoma. Despite the serious adverse reactions and the discontinuation of tumor treatment, the patient's tumor remained stable for nearly half a year, providing evidence for the delayed effect of immunotherapy.
BACKGROUND For advanced lung squamous cell carcinoma, immune checkpoint inhibitors (ICIs) have been regarded as one of the optimal therapies. While immune-related adverse events (irAEs) are common in ICI treatment, cutaneous toxicities are among the most common irAEs. Most immune-related skin toxicity grades are low, and the prognosis is good. However, Stevens-Johnson syndrome (SJS) is a rare but extremely severe cutaneous adverse drug reaction with high mortality. CASE SUMMARY We report a rare case of SJS induced by pembrolizumab. The case involved a 68-year-old female who was diagnosed with advanced squamous cell carcinoma of the lung. SJS appeared after one cycle of immunotherapy combined with chemotherapy. After treatment with prednisone hormone symptoms, anti-infection, gamma globulin, and antipruritic agents, the skin toxicity of the patients gradually decreased and eventually disappeared. Although the antitumor treatment was stopped due to serious adverse reactions, the tumor of the patient remained stable for nearly half a year after one cycle of immune therapy combined with chemotherapy, which also corroborates the delayed effect of immunotherapy. CONCLUSION We believe our report can provide some references for the treatment of SJS and the treatment of immune-related adverse reactions.
