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.
