Abstract: Extramammary Paget disease (EMPD) is a rare cutaneous malignancy, typically presenting as eczema-like lesions in areas rich in apocrine glands such as the perineum. Here, we report a case of EMPD presenting as a prominent pedunculated neoplasm in a 65-year-old woman. Despite initial misdiagnosis and treatment, biopsy confirmed EMPD infiltration. Following surgical excision, the patient developed brain metastases, indicating a poor prognosis. EMPD's pathogenesis remains unclear, but distinguishing primary from secondary forms is crucial for prognosis and treatment. Our case underscores the importance of recognizing atypical EMPD presentations for timely intervention and improved outcomes.
