Hematoporphyrin Derivative-Photodynamic Therapy (HpD-PDT) is a modality for cancer treatment, particularly suitable for challenging sites or elderly patients who can benefit from its minimally invasive and selective nature. We report a case of groin extramammary Paget's disease (EMPD) in a male patient with a lesion located in the right mons pubis. The patient was deemed unsuitable for surgical treatment due to his advanced age, underlying health conditions, extensive rash area, and the specific location of the groin lesion. He opted for hematoporphyrin photodynamic therapy instead of traditional wide local excision. The tumors were successfully treated, with no recurrence observed during the follow-up period. We suggest that hematoporphyrin photodynamic therapy may be an effective alternative to conventional surgery for the treatment of extramammary Paget's disease.
