Abstract: Objective To explore the clinical characteristics and treatment of adverse reactions in the skin of lower limbs caused by pemetrexed. Methods One case of rare skin toxicity in the lower leg caused by pemetrexed disodium for injection in a patient with non-small cell lung cancer was analyzed. The clinical manifestations and appropriate treatments of such rare skin toxicity were summarized based on literature review. Results The clinical manifestations of this patient, including swelling, erythema multiforme, itching, pigmentation, pain, sclerosis, and fever, were similar to those of pemetrexed related sclerodermic changes reported abroad, and the use of antibacterial drugs had no significant effect. After the dose of pemetrexed chemotherapy was reduced and hormone and antihistamine drugs for symptomatic treatment were used, the symptoms were significantly alleviated. Conclusion The sclerodermic changes related to pemetrexed are not included in the known adverse reactions of pemetrexed and are often misdiagnosed as cellulitis or erysipelas, which can seriously affect the quality of life of patients and deserves attention.
