Illustration of the histology (H&E) and immunohistochemistry (HMB-45) of the investigated tumor. Tumor cells are polygonal with prominent nucleoli and partially pigmented (H&E). Tumor cells express the melanoma specific protein HMB-45. Tumor cells were also positive for MELAN-A and S-100 (not shown). Scale bars represent 100 μm; magnification 400 each.
