Objective: To investigate the causes, therapeutic methods and prognosis of recurrent extramammary Paget's disease of the penis and scrotum.
Methods: We retrospectively studied the clinical presentations, therapeutic methods and prognosis of 18 cases of recurrent penile and scrotal Paget's disease, all diagnosed by biopsy and treated by surgical resection of the diseased sites. The incision reached the deep fascia. Frozen and olefin sections of the samples were pathologically examined to identify the involvement of the incisal edge. Seven cases had inguinal lymph node metastasis and underwent unilateral or bilateral inguinal lymph node resection.
Results: All the patients were followed up for 6 months to 8 years (mean 34 months). Four died of distant metastasis and the other 14 experienced no recurrence.
Conclusion: For the cases without metastasis of recurrent penile and scrotal Paget's disease, extended lesion-resection is a preferred option and the prognosis is good. And those with local lymph node metastasis need to undergo local lymph node resection.
