Two cases of segmental sporadic schwannomatosis characterized by unusual location of multiple schwannomas in digital nerves (case 1) and the superficial radial nerve (case 2) are described in this paper. In the first of the described cases, 6 tumours located at the base of the middle finger and in its distal portion were excised from both digital nerves. In the second case, 3 tumours located in the proximal 1/3 and halfway down the forearm were removed from the superficial radial nerve. In both cases, symptoms such as palpable tumour mass, pain, paraesthesias, and positive Tinel-Hoffman sign resolved after operative treatment. Final diagnoses were made based on histopathological examination results. In the second of the described cases, the largest of the excised lesions had features enabling diagnosis of a rare tumour type – ancient schwannoma.
