Schwannoma, malignant transformation, MPNST, malignant peripheral nerve sheath tumor


Background: Peripheral nerve sheath tumours are benign or malignant. Schwannoma is a benign peripheral nerve sheath tumour originating from Schwann cells that slowly grows eccentrically to the nerve axis. Malignant transformation of a schwannoma is rare.

Case presentation: A 73-year-old woman who presented to our medical service with other medical problems was diagnosed with a tumour of the lower leg (a small mass neglected by the patient for about 10 years). The ultrasound features of the tumour suggested it was a schwannoma. The tumour was resected and histopathological assessment revealed a schwannoma with areas of malignant peripheral nerve sheath tumour transformation.
