Figure 4

Pathologic findings: (a) pigmented tumor composed of fusiform cells with brownish cytoplasm (hematoxylin-eosin stain, original magnification 10x). Two different zones: (b) the first one is highly pigmented with brownish cytoplasm, and (c) the second zone is less pigmented where we can see the nuclear details: fusiform cells with elongated nuclei and small nucleoli, without necrosis, atypia, or mitotic activity (hematoxylin-eosin stain, original magnification 40x).
