Paratesticular malignant peripheral nerve sheath tumour: a case report

Primary malignant peripheral nerve sheath tumours (MPNST) of intrascrotal extra testicular site are extremely rare with only few cases reported in literature. These are highly malignant tumours most often associated with neurofibromatosis. The incidence in general population is 0.001%. A 35-year-old male presented with swelling of the scrotal sac of three months duration. There were no features of neurofibromatosis. The lesion was excised and was diagnosed as MPNST. The patient developed recurrence within two months.
