Figure 1
Keywords: Schwannoma, Histopathology-image, Pathology
In schwannoma, sections show an encapsulated well-circumscribed lesion beneath the uninterrupted epidermis. The tumour is composed of different areas composed of different cellular densities. More cellular areas (Antoni A, figure 1) are composed of a haphazard arrangement of bland cells with spindled and oval nuclei. Loose, less cellular areas (Antoni B, figure 2) are composed of a loose oedematous and mucinous stroma with fibrillar collagen. The vessels are prominent and often surrounded by a dense sclerosis.
