Penile Melanoma In Situ: Long Term Follow Up

Abstract

Penile melanoma in situ is extremely rare. Various treatments have been reported with good success, however follow up is generally limited to 1 year or less. The optimal treatment regimen, pattern of disease progression and utility of sentinel lymph node biopsy are not established. We provide the longest reported follow up for penile malignant melanoma in-situ, highlighting a long-term pattern of recurrence and a route of progression which does not follow more reliable patterns of lymphatic spread known to penile squamous cell carcinoma. A cautious approach should be taken for organ-sparing approaches along with proper patient counseling and close, long-term follow-up.
