Abstract
Introduction: The aim of this paper is to report a rare case of a sizeable low grade malignant schwannoma of the posterior tibial nerve and to underline the method of treatement.
Case Report: A 37-year-old white male presented himself with a slowly growing mass in his left calf. According to the slower rate of growing and to the mobility of the tumor diagnosis was oriented to a benign lesion of posterior calf muscles. The decision was to perform a excisional biopsy of the tumor. The examined tumor was classified as low-grade malignant peripheral nerve sheath tumor. We did not have a suspicion of malignancy in our case due to the slowly growing rate. The treatment performed was surgical excision of the tumor with adequate exposure of normal nerve proximally and distally.
Conclusion: Clinical and radiological findings of this case suggested a benign tumor. According to this, the decision was to perform a excisional biopsy of the tumoral mass and not only a biopsy first.

Keywords: Malignant schwannoma, Marginal excision, Survival rate, Neurofibromatosis, Tibial nerve
