Introduction:
Schwannomas, also known as neurilemmomas, are the most common benign peripheral nerve tumors. Schwannomas arising from deep peroneal nerves are rare and often remain clinically silent until local mass effects cause pain, dysesthesia, or motor/sensory deficits.
Case Report:
A 20-year-old female presented with a 6-month history of pain and swelling in her right leg, with difficulty in standing and walking for longer durations. Imaging revealed a well-defined lesion along the deep peroneal nerve. Surgical enucleation of the tumor was performed, and histopathological examination confirmed the diagnosis of schwannoma. Postoperatively, the patient experienced a significant improvement in symptoms with no recurrence at the latest follow-up.
Conclusion:
Schwannomas arising from deep peroneal nerves are rare. However, they should be considered in patients with chronic leg pain and swelling with neurological symptoms in the leg and calf region. Surgical excision is the treatment of choice, and complete resection is generally curative.
