Abstract：
Mycosis fungoides palmaris et plantaris (MFPP) is a rare variant of mycosis fungoides (MF), a type of cutaneous T-cell lymphoma. MFPP primarily affects the palms and soles of the feet and is often misdiagnosed as dyshidrotic eczema due to its similar clinical presentation. This case report presents a middle-aged woman with MFPP whose initial presentation was mistaken for dyshidrotic eczema. Despite treatment with topical corticosteroids, the patient\'s lesions persisted, prompting further investigations that led to the diagnosis of MFPP. The patient was initiated on betamethasone dipropionate ointment and hydroxyzine for pruritus management, with a pivotal referral to oncology for comprehensive evaluation. This case highlights the importance of considering MFPP in the differential diagnosis of persistent eczematous lesions on the palms and soles, especially when treatment with topical corticosteroids is ineffective.

摘要：
真菌病（MFPP）是真菌病（MF）的罕见变种，一种皮肤T细胞淋巴瘤.MFPP主要影响手掌和脚掌，由于其相似的临床表现，经常被误诊为汗症湿疹。该病例报告介绍了一名患有MFPP的中年妇女，其最初的表现被误认为是汗症湿疹。尽管用局部皮质类固醇治疗，病人的病变持续存在，促使进一步的调查，导致MFPP的诊断。患者开始使用二丙酸倍他米松软膏和羟嗪治疗瘙痒，关键转诊到肿瘤学进行综合评估。该病例强调了在手掌和足底持续性湿疹病变的鉴别诊断中考虑MFPP的重要性。特别是当局部用皮质类固醇治疗无效时。J药物Dermatol.2024；23（7）：569-570。doi:10.36849/JDD.8474。
