ABSTRACT


Introduction: A primary malignant melanoma of the vagina (PMMV) is a rare and aggressive disease. At the time of diagnosis the tumors are mostly already large in size thus entailing a high risk for local recurrence and distant metastasis. Various treatment regimens such as local wide excision, radical surgical procedures, and nonsurgical treatment (primary radiotherapy, chemotherapy, and immunotherapy) have been described in literature. A standard treatment protocol has not yet been defined.

Case Report: We present an 89-year-old woman with abnormal vaginal bleeding, resulting in a malignant melanoma of the vagina. The tumor size revealed in magnetic resonance imaging (MRI) scan was 6.6 × 3.2 cm with close localization to the rectal wall. We recommended radical surgery to achieve free margins which she refused. Despite good local response after primary radiotherapy she died six months later because of distant metastasis.

Conclusion: In PMMV primary radiotherapy is a valuable treatment option whenever surgery is not feasible or refused by the patient. As we described in our case local control is achievable but the life limiting risk of distant metastasis remains. Further investigation to define a standard treatment protocol is needed.
