A case of head pedunculated malignant melanoma.Head pedunculated malignant melanoma with clinically difficult diagnosis.

We report a case of amelanotic polypoidal (pedunculated) melanoma of the scalp. This case is very difficult for diagnosis of malignant melanoma clinically. The patient was operated it by former doctor under the diagnosis of fibroma, but histological findings revealed malignant melanoma, so consulted to our clinic. We confirmed malignant melanoma histologically, extending to Clark's level IV, Breslow's tumor thickness: 6.8mm, pT3 N0 M0, Stage II. We performed it wide excision, skin graft and chemotherapy. Until now, we can not find local recurrence and metastatic lesion.Pedunculated Malignant Melanoma (PMM) is considered as a variant of the Nodular Melanoma (NM), and recently, it is not so rare growth pattern. Therefore when we face to pedunculated tumors, we should remember PMM.
