“…The mostly affected nerves are ulnar and median nerves [8]. There are several cases of multiple schwannomas of median nerve reported in the literature [9–14]. Wrist and palm involvement similar to our case is reported only in one of these studies [15].…”

Schwannomas are also known as neurolemmas that are usually originated from Schwann cells located in the peripheric nerve sheaths. They are the most common tumours of the hand (0.8–2%). They usually present solitary swelling along the course of the nerve however multiple lesions may be present in cases of NF type 1, familial neurofibromatosis, and sporadic schwannomatosis. Schwannomas are generally represented as an asymptomatic mass; however pain, numbness and fatigue may take place with the increasing size of the tumour. EMG (electromyelography), MRI (magnetic resonance imagination), and USG (ultrasound) are helpful in the diagnosis. Surgical removal is usually curative. In this paper, we present a 24-year-old male referred to our clinic for a lump located at the volar side of the left wrist and a lump located in his left palm and numbness at his 3rd and 4th fingers. Total excision was performed for both lesions. Histopathological examination of the masses revealed typical features of schwannoma. At the 6th-month followup the patient was symptom-free except for slight paresthesia of the 3rd and the 4th fingers. For our knowledge, this is the second case in the literature presenting wrist and palm involvement of the median nerve schwannoma.

“…Eradication of regional schwannomatosis is a challenging surgical problem because of the difficulty in localizing small tumors and the propensity for multiple recurrences. 9 It is also complicated by the intimate involvement of the nerves or nerve plexuses; however, sacrifice of neural elements is contraindicated.…”

Schwannomatosis is a rare neoplastic condition of unclear etiology characterized by multiple schwannomas in the absence of other manifestations of neurofibromatosis. In very rare cases, these tumors develop in an isolated region of the body. Complete removal of these tumors presents a surgical challenge because they are often small and difficult to locate. We found that intraoperative sonography offers invaluable assistance in such cases by localizing small schwannomas and decreasing operative time and extent of the surgical dissection.

“…The treatment of choice is complete excision of the schwannoma as the nerve fibres are displaced and do not enervate the tumour 5. During surgical excision, careful dissection after longitudinal incision of the epineuria and avoidance of nerve retraction are vital so as to avoid neurological deficits…”

A 79-year-old Caucasian woman with rheumatoid arthritis (RA) for 27 years presented with a swelling on her left wrist. Both pain and a tingling sensation in the radial four fingers could be elicited by applying light pressure on the swelling. The patient was uncertain as to the actual onset of this swelling and had not complained, as it resembled many of the swellings of the hand region she had previously experienced. Primarily, an organised tenosynovitis was suspected with a presumed pressure on the median nerve, and a puncture was considered. Ultrasonography diagnosed a large hypoechoic mass. This is not unusual with longstanding inflammatory changes, which may contain elements of connective tissue. Using the Doppler function it turned out to be highly vascularised. The tumour could not be removed, but histology revealed a diagnosis of schwannoma.
