The effect of proximal epineural stripping on neuroma formation was studied in the peroneal nerve stumps of the rat. After transection of the peroneal nerve, the epineurium of the proximal stump was stripped back by 6 to 8mm and the nerve fascicles left uncovered in the study group. The transected nerve was left untreated in the control group. All nerves were evaluated by light microscopy 6 months after the operation. Two neuromas occurred in 20 stumps after epineural stripping while 15 neuromas occurred in the control group. Based on histological data, we conclude that stripping of the epineurium may inhibit neuroma formation in the rat.

Malignant fibrous histiocytoma is the most common type of soft tissue sarcoma in late adult life. The tumour may be seen rarely in burn scars and accompanying other kinds of malignancies. We herein report a case of a tumour that derived from an old burn scar on the scalp. The histological examination revealed that the tumour contained both malignant fibrous histiocytoma and squamous carcinoma areas. Malignant transformation in a burn scar is a well-known development; therefore, a new lesion occurring within the scar should not be neglected.
