Histopathological findings of traumatic breast neuroma. (A) The tumor consists of haphazardly arranged, eosinophilic cells with oval to spindle nuclei, without atypia, necrosis or mitosis. (Hematoxylin and Eosin ×400); (B) Tangles of small and medium, well circumscribed nerve fiber bundles, that do not invade the surrounding fibroadiposal tissue.(Hematoxylin and Eosin ×100); (C) High power photomicrograph, of eosinophilic cells, with bubbly cytoplasm, bland, oval to spindle nuclei, without significant atypia. The periphery of the nodule is composed of perineural cells, while the inside consists of proliferated Swann cells. (Hematoxylin and Eosin ×400).
