Background Schwannomas, also known as neurilemomas, represent the prevailing non-malignant neoplasms affecting the peripheral nervous system. Benign neoplasms affecting the peripheral nerves of the upper extremity are infrequent in occurrence. Typically, these neoplasms arise from Schwann cells situated within the peripheral nerve sheaths. Schwannomas, which are benign tumors found in peripheral nerves, are observed to be the prevailing type, accounting for approximately 5% of all tumors occurring in the upper extremity. Schwannomas involving the median nerve are observed at a frequency ranging from 0.1% to 0.2% among the entirety of hand tumors. Schwannomas typically manifest as a source of patient discomfort. The observed edema has the potential to be erroneously identified as a ganglion, lipoma, or lymph node. Neuromas manifest as a hyperplastic and disorganized growth of cells, which arises as a response to nerve injury, signifying an endeavor towards nerve regeneration. These neuromas can be categorized into two types: terminal neuromas and in-continuity neuromas. Magnetic resonance imaging (MRI) and ultrasound imaging techniques have proven to be valuable tools in the diagnostic process. The curative approach typically involves the implementation of surgical removal. |
