Amelanotic melanoma and pyogenic granuloma. Peculiarities of the differential diagnosis

Abstract

INTRODUCTION: Nodular melanoma is a rapidly progressive skin tumour with a high risk of methastasis even on early stages. This fact leads to necessity of non-invasive procedures, which can verify this diagnosis before surgery. Nodular forms of amelanotic melanoma can be hardly diagnosed because of their unusual diagnostic and dermatoscopic features.

CASE REPORT: Pyogenic granuloma is the most difficult disease for differential diagnosis. It is a benign vascular formation, which mimics nodular amelanotic melanoma.
