Primary anaplastic lymphoma kinase-negative anaplastic large cell lymphoma of cervical spine presenting with quadriplegia: A case report and literature review

Background An anaplastic large cell lymphoma (ALCL) involving the cervical spine and leading to quadriplegia is very rare. Case Description A 48-year-old immunocompetent male presented with quadriplegia that warranted an anterior cervical corpectomy/fusion. He was previously being presumptively treated for cervical disease attributed to tuberculosis. The histopathology and immunohistochemistry revealed an ALCL that was anaplastic lymphoma kinase (ALK) negative. The patient had a favorable response to surgery followed by CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisolone) chemotherapy. Conclusion ALK-negative ALCL presenting with quadriplegia due to primary involvement of cervical spine is extremely rare, but must be diagnosed and appropriately managed.
