A crimson, dome-shaped tumor with a granular, spongy surface (diameter 4cm) had developed over a period of about 3 months. The biopsy, stained with Hand E, revealed an anaplastic malignant tumor. Additional immunochemical staining with Melan A allowed us to make the final diagnosis: amelanotic malignant melanoma (MM). The melanoma was removed by amputation of digits IV and V, with partial removal of the metatarsal bones (Clark degree 5, Breslow thickness 9 mm). Sentinel node biopsy was done using Tc99; it revealed no neoplastic alteration. The patient is still under oncological observationTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZdruženje slovenskih dermatovenerologov
