Pediatric Malignant Glomus Tumor of the Cervical Paraspinal Tissue: Case Report and Review of the Literature

Glomus tumors are mesenchymal tumors that arise from glomus bodies and most frequently occur in the distal extremities. These tumors can occur throughout the body and are typically benign. However, a very small fraction of glomus tumors displays aggressive features and are considered atypical or malignant. We report on our experience and management of the first case in the literature of a malignant glomus tumor in a child originating in the paraspinal region with involvement of the cervical spine. Malignant glomus tumors tend to be locally aggressive, and en bloc resection is difficult, especially when the tumors occur in the head and neck. Additional studies on disease progression and adjuvant treatment outcomes are necessary to determine the best treatment approach and long-term outcomes in patients with malignant glomus tumors.
