Although Lymphomas are considered to be tumours of the lymph nodes, a substantial number arises at other sites. The breast is an unusual and very rare primary site. Few series have been reported in the international literature available which accomplished the Wiseman and Liao criteria 9 . Nine cases of primary malignant lymphoma of the breast were found in the files of the Path. Dept. of our Hospital, in a period of five and a half years (1985-1990). In the same period 6006 breast biopsies were examined, out of which 2181 cases were adenocarcinomas and 25 sarcomas. All cases met the criteria proposed by Wiseman and Liao⁹. All patients were women 23 to 83 years old, with mean age of 64.1 years. Histologically Our Cases were reviewed and classified according to Lennert's and Working Formulation classification and all were non-Hodgkin's lymphomas.
