CATARINO, Isabel et al. Schwanoma da mão: A propósito de um caso clínico. Rev. Port. Ortop. Traum. [online]. 2018, vol.26, n.3, pp.253-259. ISSN 1646-2122.

The soft tissue tumours of the hand are seen on a regular basis by the hand surgeons, representing 15% of all soft tissue tumours. Although the vast majority of the lesions are benign, it is important to consider chances of malignancy if existing signs and/or symptoms¹. The most common benign soft tissue tumours of the hand are lipoma, fibroma, neurofribroma, ganglion, giant cell tumours and xanthoma^2,3. Schwannomas are benign nerve sheath tumours composed of Schwann cells. The chances of becoming malign are low^1,2, and, despite being the most frequent peripheral nerves tumour⁴, they only represent 0,8-2% of all hand tumours^2,5. The authors describe an atypical study case of a patient with a swelling on the palmar surface of the hand caused by the co-existence of two soft tissue tumours: one lipoma and one giant schwannoma of the palmar digital branches of the median nerve whose diagnosis was only achieved through surgery.
