Traumatic neuromas: A histopathologic and immunohistochemical study [Travmatik nöromalar: Histopatolojik ve i·mmünohistokimyasal bir çalişma]

Objective: Traumatic neuroma is an exuberant, probably non-neoplastic proliferation of a nerve occurring in response to injury or surgery. We studied six cases of traumatic neuroma with light microscopic, histochemical and immunohistochemical methods to assess the cellular compositions of these lesions. Material and Methods: Sections from the formalin-fixed parafin-embedded tissues were stained with hematoxylin-eosin, Gomori's trichrome, Verhoeff elastica-von Gieson, reticuline, and S-100 protein, Epithelial Membrane Antigen, CD34 and CD68. Results: All cases revealed large numbers of small and haphazardly arranged regenerating nerve fascicles within a densely collagenous and fibroblastic stroma. A focal chronic mononuclear cell inflammatory reaction was observed in three cases. In all cases, Gomori's trichrome revealed collagen. Axonal morphology was detected in nerve fibers histochemically by reticulin. In all cases, fascicles were stained diffusely with S-100 protein, and Epithelial Membrane Antigen showed a positive reaction in a thin band of cells surrounding the fascicles in three of the cases. CD34 positive cells were present in five cases. CD68 expressing cells were present in only in two specimens. Conclusion: In traumatic neuromas, specific staining of fascicles with S-100 protein, perineural cells reactive for Epithelial Membrane Antigen and the presence of CD34 positive cells may contribute to our understanding of their pathogenesis and differentiation of these lesions from mimickers.
