138 that is believed to be immunologically mediated. Approximately two-thirds of cases are related to a recent respiratory
- r gastrointestinal tract infection, espe-
ciallyinfectionsduetoCampylobacterjejuni, cytomegalovirus, and Epstein-Barr virus [3]. Guillian-Barre syndrome has been reported to be associated with some sys- temic processes such as Hodgkin’s lym- phoma, human immunodeficiency virus andsystemiclupuserythematosus[4]. This is the first report of Guil- lian-Barre syndrome in a patient with intravascular lymphoma. Regarding our patient we cannot provide data dif- ferentiating between immune mediated polyneuropathy and vascular damage to multiple nerves as the basis for this presentation. The patient’s diagnosis was elusive due to misinterpretation
- f the initial skin biopsy. Skin biopsy
determines the diagnosis in a large proportion of intravascular lymphoma patients. The first manifestation in our patient was panniculitis-like lesions diagnosed mistakenly as erythema no- dosum 2 years prior to her neurologic symptoms. Recent evidence suggests that in contrast to previous reports, hepatosplenic involvement (26%) and bone marrow infiltration (32%) were found to be common features in in- travascular lymphoma, while nodal disease was confirmed
rarely (11% of cases) [5]. When our patient presented with Guillian-Barre syndrome her disease was already disseminated and prognosis was poor. Had treatment been initiated earlier, prognosis might have been better. We would like to em- phasize the importance of considering thisdiseaseinthedifferentialdiagnosis in any patient presenting with unclear disease suggesting small vessel dis- ease. A definite clinical suspicion can aid the pathologist in achieving earlier diagnosis, thus improving the patient’s prognosis.
