Silent Trauma: A Forearm Neuroma With No Traumatic Clue

Abstract

Introduction: Traumatic neuroma is a rare, benign nerve tissue proliferation resulting from injury or surgery. It occurs when nerve regeneration is disrupted, forming a tumour-like growth. This condition, most common in middle-aged women, is characterized microscopically by neural tissue patterns, stroma, inflammatory infiltration, and vascularity. Case presentation:  A 33-year-old male presented with a 10day history of swelling on the left forearm without trauma or surgical history. Examination revealed a firm, non-adherent 2 x 2 cm swelling. Initial imaging suggested various diagnoses. The lesion was excised, and histopathology confirmed  a traumatic neuroma with mature ganglion cells. The patient remained symptom-free for one year post-surgery. Conclusion:  Traumatic neuroma should be considered in differential diagnoses of  forearm swellings, even without clear trauma history. Surgery is effective, but further research into non-surgical treatments and recurrence prevention is needed to enhance management and outcomes.
