[Treatment with imiquimod and surgical excision of a patient with extramammary Paget's disease. Case report]. / Tratamiento con imiquimod y escisión quirúrgica en un paciente con enfermedad extramamaria de Paget. Caso clínico.

Extramammary Paget's disease (EMPD) is a less common cutaneous type of cancer. It presents as erythematous plaques most frequently located in the genital region, perianal skin, and other cutaneous sites rich in apocrine glands, but it also may originate from keratinocytic stem cells. Recently, imiquimod has been used for the management of primary or relapsing extramammary Paget's disease. Complete healing, without recurrence, of extramammary Paget's disease in patients whom were treated topically with 5 % imiquimod cream was observed. We report a 78 year-old patient with scrotal and perianal extramammary Paget's disease treated with imiquimod cream in both lesions and subsequently with surgical excision in scrotum for the management of relapsing disease.
