Blue Nevus of the Hard Palate: The Importance of a Careful Examination in an Emergency Setting

Figure 2

Microscopic examination at magnifications 40x (a) and 100x (b) with hematoxylin and eosin. There is a noncircumscribed submucosal proliferation of elongated spindle-shaped melanocytes that are grouped in short fascicles some of them arranged parallel to the overlying epithelium. The melanocytes contain a variable amount of melanin pigments in the cytoplasm. Some fibrosis is observed in between the fascicles of pigmented cells. There is no atypia or areas of necrosis. No mitoses were observed.
