A 75-year-old male patient showed an extensive erosion mainly restricted to the penile site, which was found when he received appendectomy. The penile lesion had persisted for about ten years, during which period the erosion extended gradually while he missed to consult a physician. The lesion was a florid and wetting erosion, with a definite boundary, which covered the entire circumference of the penile foreskin and also extended to the suprapubic area, scrotum and external urethral orifice. Although the diagnosis could not be made by biopsy, extra mammary Paget’s disease was strongly suspected. Bilateral modified inguinal lymphadenectomy and systemic evaluation were first performed to confirm that there was no metastasis or complexed disease in other organs. Then extensive wide resection of the skin lesion and reconstruction using a split-thickness skin graft were performed. Histopathological examination of the surgical specimen revealed poorly differentiated squamous cell carcinoma, although most part showed only inflammatory erosion. Clinical course and the histopathological findings including specific staining patterns led to the diagnosis of poorly differentiated squamous cell carcinoma originated from erythroplasia. During post-operative 18 months until now, no local recurrence or distant metastasis has been observed.
