Primary non-Hodgkin lymphoma of the spine.

Primary non-Hodgkin lymphoma (PHL) occurs very rarely in bone. We report a case of a 63-year-old patient with PHL of the spine and an unusual postoperative complication leading to the development of a perforation of the transverse colon. After right hemicolectomy the patient recovered fully and was further treated with chemo- and radiotherapy. We emphasise the importance of an immunohistochemical analysis to exclude misdiagnosis.
