A case of pedunculated malignant melanoma

Pedunculated malignant melanoma is a rare type of melanoma. It has long been considered to be the more aggressive variant of nodular melanoma. It has an earlier age of onset and commonly presents as an exophytic lesion which frequently ulcerates and does not necessarily appear pigmented, allowing it to be confused with benign conditions such as pyogenic granuloma, intradermal nevus, or a fibroepithelial polyp. We report a case of a pedunculated malignant melanoma presented with a pedunculated reddish nodule on the left upper arm of a 31 year-old man.
