Abstract
INTRODUCTION Plasmacytomas, considered to be the solitary counterparts of multiple myeloma, are neoplastic monoclonal plasma cell proliferations within soft tissue or bone. Plasmacytomas often present as a collection of findings known as POEMS-syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, M-Protein spike, and Skin changes). CASE DESCRIPTION We present a report of a 47 yo male diagnosed with POEMS-syndrome secondary to a skull base plasmacytoma. The mass resulted in marked instability of the cranio-cervical junction due to bony erosion. Following an induction course of chemotherapy, he showed clinical improvement with a marked reduction in tumor size and underwent an autologous peripheral blood stem cell transplant for systemic treatment of his POEMS-syndrome. Following completion of systemic treatment, he then underwent a definitive occipital-cervical fusion without complications. His neurologic exam upon dismissal was stable with subjective improvement in left upper extremity strength. Postoperative radiographs confirmed spinal alignment and pathological examination of a small biopsy from C1 revealed benign fibrous tissue. CONCLUSION To the best of our knowledge, this is the first report of a skull-base plasmacytoma associated with POEMS-syndrome, causing cranio-cervical instability. The approach of systemic therapy combined with temporary external fixation, followed by definitive occipital cervical fusion resulted in a good outcome for this patient.

Abstract
BACKGROUND AND AIM Vertebral involvement is a common occurrence in myelomas, but isolated involvement of the high cervical spine is exceptionally rare. This factor, together with the pediatric age of our patient, makes this case the first report of a plasmocytoma involving C1. CASE REPORT A 14-year-old boy, without neurological involvement, presented with cervical pain and a palpable posterior neck mass. Cervical spine radiographs showed an osteolytic lesion at C1 compressing the cervical spinal canal and instability of the craniocervical junction. After a complete study, the patient was diagnosed with solitary plasmocytoma. A sequential treatment was instituted that consisted of radiotherapy after craniocervical junction stabilization with an halo-jacket, followed by occipitocervical stabilization with instrumented arthrodesis that was accompanied by resection of the residual C1 tumor and, finally, with consolidation of the oncological treatment with further radiotherapy. CONCLUSION The treatment of choice for a cervical solitary plasmocytoma consists of a combination of chemotherapy, corticosteroids, radiotherapy, and immunotherapy, but the main neurosurgical problem is the craniocervical instability as occurred in other tumor of the cervical column.
