Extramammary Paget’s disease (EMPD) is a rare and heterogeneous clinical picture usually recorded on apocrine gland-bearing epidermis areas in extramammary sites, showing a potential invasive evolution and poor prognosis. At diagnosis, it could appear as a primary tumor with secondary co-exhisting visceral malignancies like in anus, male or female genital system, which should be assessed. This rare epidermal carcinoma generally occurs in individuals older than 60 years mainly in Caucasian female and Asian male ethnicity. Although the pathophisiology has been well established, its management is still controversial and requires a multidisciplinary team approach. There are several therapeutic strategies. Among them, radiotherapy is accounted as an effective option in primary or in adjuvant timing but up to now no definitive role has been assessed. Data by case series, case reports and retrospective analyses have provided results on the positive benefit of HDR brachytherapy or external beam radiotherapy (EBRT) mainly in very old patients not suitable for extended surgery, which remains the main treatment care. Long course radiotherapy is a big concern in elderly patients due to logistics and care assistance deficiencies, which makes their access difficult to the radiation centres. Thus, hypofractionated radiotherapy regimens could be a good compromise problem solving to provide excellent local control within a short treatment time. Herein, we present a case of EMPD occurring in a 80 years old woman with vulvo-perineal extension successfully treated with hypofractionated external beam radiotherapy as primary treatment using a schedule 300cGy/fr/51 Gy in 17 treatment days.
