GIANT SCHWANNOMA OF THE LEG – A RARE CASE REPORT

Abstract

Schwannoma is a benign tumour of the peripheral nerve sheath originating from the Schwann cells that grows slowly eccentric to the nerve axis and is a rare occurrence in the lower limb. Peripheral nerve sheath tumours are common neoplasm with different biological features ranging from benign to malignant. They are mostly misdiagnosed as benign soft tissue skin condition, such as lipoma, myxoma, or ganglion cyst. Most of these tumours are less than 5 cm in size, whereas those larger are termed giant schwannomas. Malignant transformation of a schwannoma is rare. The usual symptoms of schwannoma of the lower limb are tingling, burning sensations signifying peripheral neuropathy and weakness, paralysis of the affected limb denoting motor impairment. Magnetic resonance imaging and biopsy are the most useful diagnostic methods followed by surgical excision, which is the treatment of choice. Postoperative complications are minimal and rare. Here, we report a case of a giant schwannoma and its management by surgical excision and the resultant defect resurfaced with a pedicled flap.
