“…Recurrence of median nerve schwannomas following total excision is unlikely in most of the cases 13 , but up to half of the patients undergoing surgery can develop neurological deficits 14 . Early diagnosis of the tumor before the nerve is infiltrated, followed by microsurgical excision of the tumor, can be very instrumental in the preservation of nerve function 15 .…”

Introduction: Schwannomas are benign tumors of the peripheral nerve sheath and the median nerve is the most commonly involved nerve. These benign tumors of the peripheral nerve sheath are very rare, they are clinically and radiologically similar to most other benign swellings of the hand, thus they are often misdiagnosed. Case Presentation: A 41-year-old lady presented with an eight-year-long history of swelling over the distal forearm. The tumor measured 3.5*3.5*3.5 mm and was located over the flexor aspect of the distal part of her right forearm. Schwannoma was suspected from the clinical presentation and imaging, but the final diagnosis was established only after the surgery and histopathological analysis. At the follow-up after 1 year, the patient is doing well and her symptoms have not recurred. Conclusion: Imaging characteristics of schwannoma can be misinterpreted as some other condition, making the preoperative diagnosis very difficult and important. Thus, clinicians should be aware of such swellings, especially those that have been unnoticed or misdiagnosed, and provide optimal diagnoses to confer good outcomes.

Introduction: Schwannoma, also known as neurilemmoma is a rare tumor, but it is one of the most common tumors of the peripheral nerves. It originates from Schwann cells of the peripheral nerve sheaths. Schwannoma mostly occurs in adults at the age of 20 to 70. The most common regions are head and neck, but it can occur almost anywhere in the body, or in its organs. Schwannomas are usually up to 2.5cm in size but they may grow up to 4-5. In this paper, the rare case of large Schwannoma of the median nerve in the distal part of the forearm is presented. Case report: A 46-year-old male patient was referred to a plastic surgeon with a diagnosis of lipoma on the anterior side of the distal third of the left forearm. Ultrasound and magnetic resonance imaging were performed and the surgery was done after that. An encapsulated tumor of the median nerve was found, and the tumor was completely removed, without nerve damage. Histological analysis showed a benign Schwannoma of cellular type and biphasic shape. In the postoperative course, there was transient paresthesia. One year after surgery, no tumor recurrence nor neurological deficit were recorded. Conclusion: Schwannoma is the most common benign tumor of peripheral nerves. Schwannomas over 5 cm in size are extremely rare. Appropriate physical examination, preoperative imaging studies, and histological verification are required for the final diagnosis. The method of choice in the treatment of large Schwannomas is complete surgical excision.
