Primary non-Hodgkin lymphoma (PHL) occurs very rarely in bone, We repo
rt a case of a 63-year-old patient with PHL of the spine and an unusua
l postoperative complication leading to the development of a perforati
on of the transverse colon. After right hemicolectomy the patient reco
vered fully and was further treated with chemo- and radiotherapy. We e
mphasise the importance of an immunohistochemical analysis to exclude
misdiagnosis.
