KI-1 POSITIVE NON-HODGKINS-LYMPHOMA REVEA LED BY CUTANEOUS AND MUCOSAL ULCERATIONS AND GLOMERULONEPHRITIS

Malignant lymphoma particularly of T phenotype can be associated with specific or non specific cutaneous lesions. These cutaneous manifestat ions can occur at the onset of the disease being sometimes the reveali ng sign or they can appear during the course of the lymphoreticular ma lignancies. Glomerulonephritis was also described in lymphoma. Ki-1 po sitive large cell lymphoma was recently identified. A new case is repo rted with lymphadenopathy and intestinal localisation revealed by cuta neous and mucosal ulcerations principally in the mouth and a focal seg mental glomerulonephritis with endo- extracapillary proliferation. The absence of lymphoma in cutaneous and renal lesions and the clinical p resentation support the hypothesis of paraneoplastic manifestations, m ay be related to a vasculitis.
