A schwannoma is a benign tumour of Schwann cells that presents as a palpable and painless mass on the volar aspect of the hand and wrist. A 44-year-old, right-handed woman, presented for a volar swelling of her right hand. On examination she had a non-pulsatile mass with no fluctuation at the radiopalmar aspect of the right hand, and a soft mass on the volar aspect of the right palm. ⋯ It is difficult to differentiate schwanommas from neurofibromas solely on the basis of an MRI. Neurofibroma grows intraneurally and infiltrates the nerve; it has the potential to require resection of all or part of the nerve, leaving a consequent functional deficit. Tumours of the hand are diagnostically challenging and median nerve shwannomas are rare.
