Eczema with Skin Infection Misdiagnosed as Severe Drug Eruption in a Patient with Pancreatic Malignant Tumor: A Case Report

摘要: 本文报告一例60岁女性胰腺恶性肿瘤患者湿疹伴皮肤感染误诊为重症药疹的诊疗过程。患者因“全身散在红斑丘疹伴瘙痒2年，加重伴皮肤疼痛、下肢水肿伴糜烂1周”入院，初步诊断重症药疹，经实验室及病理学检查后修正诊断为“湿疹伴皮肤感染”，本病例通过及时调整治疗方案(抗感染 + 皮肤屏障修复)实现好转，印证了精准诊断的重要性，结合临床表现与病理检查分析误诊原因，旨在为临床鉴别此类皮肤病变提供参考，避免诊疗延误。

Abstract: This article reports the diagnosis and treatment process of a 60-year-old female patient with pancreatic malignant tumor who had eczema complicated by skin infection, which was initially misdiagnosed as severe drug eruption. The patient was admitted to the hospital due to “diffuse erythematous papules all over the body with pruritus for 2 years, aggravated with skin pain, lower extremity edema and erosion for 1 week”. She was initially diagnosed with severe drug eruption, and the diagnosis was revised to “eczema with skin infection” after laboratory and pathological examinations. The patient achieved improvement through timely adjustment of the treatment plan (anti-infection + skin barrier repair), which confirms the importance of accurate diagnosis. By analyzing the causes of misdiagnosis based on clinical manifestations and pathological examinations, this case aims to provide reference for clinical differentiation of such skin lesions and avoid delays in diagnosis and treatment.
