Figure 4: (a) Photomicrograph (hematoxylin and eosin, 40×) showing coarse brown cytoplasmic pigment within the melanoma cells. Inset shows cytoplasmic positivity of HMB-45 immunostain. (b) Photomicrograph (hematoxylin and eosin, 40×) of the parietal lobe mass showing meningothelial whorls and fascicles of meningioma. Inset shows membranous positivity of epithelial membrane antigen (EMA) immunostain
