原发性乳腺恶性淋巴瘤２例报告，并复习自１９８８年至１９９４年国内文献共１２９例资料。其中男性３例，女性１２６例，平均年龄４１岁；在完整的临床和病理资料８９例中，单侧７０例（７８．７％），其右左之比为３７：３３；双侧１９例（２１．３％）。在有随访资料的１１５例中，１、３、５年存活率分别为５８．３％、２７．８％和１４％，预后非常恶劣。在国内的原发性乳腺恶性淋巴瘤与乳癌临床上甚难鉴别，对此有关问题作一讨论。 Primary breast malignant lymphoma was reported in 2 cases, and a total of 129 cases of domestic literature from 1988 to 1994 were reviewed.
