A rare presentation of supraclavicular schwannoma

Abstract

Schwannomas or neurilemmomas are benign tumors that arise from Schwann cells that surround the peripheral, cranial, or autonomic
nerve sheaths. These are slow-growing, benign, encapsulated tumors that arise from the proliferating Schwann cells, encompassing the nerve sheath. About 25–45% of the schwannomas are found in the head-and-neck region. These tumors can arise from any of the cranial, peripheral, or autonomic nerves and constitute <1% of the tumors seen in the head-and-neck region. In the present case, the tumor was in the lateral group, localized to the right-sided supraclavicular region, and originating from the cervical or brachial plexus. We present the case of a 44-year-old gentleman who presented with a right-sided supraclavicular swelling for 2 months, which initially was thought to be a lymph node mass but which turned out to be a schwannoma on the pathological and radiological diagnosis.
