Concurrent manifestations of primary extramammary Paget’s disease involving the left axilla and the left groin with nodal and bone metastasis

Abstract

Primary extramammary Paget's disease (EMPD) is a rare type of skin cancer, as a less aggressive intraepithelial adenocarcinoma. Patients usually present with skin lesions at apocrine gland sites such as the vulva, penoscrotal area, perianal area, umbilical area, and, less commonly, the axilla. EMPD is primarily an intraepidermal neoplasm but has the potential to invade deeper structures and metastasis. This case report presented a patient diagnosed with concurrent sites of primary EMPD, with one site showing nodal and bone metastasis. Making an accurate diagnosis of EMPD can be challenging as case occurrences are rare.
