Primary Extramammary Paget's Disease in a Male Patient Exhibiting Genital Involvement Mimicking Clinical and Histopathological Features of Bowen's Disease: A Case Report.

Extramammary Paget's disease (EMPD) is a rare cutaneous neoplasm characterized by the proliferation of malignant glandular-origin cells within the epidermis, occurring in areas other than the mammary areola. It is more prevalent in women (65%) than men (14%). Diagnosis can be confused with other neoplastic, inflammatory, or infectious conditions, often leading to initial inappropriate treatment with antifungals or topical steroids.
