恶性淋巴瘤是较为多见的淋巴网状组织恶性肿瘤。可发生于各种年龄,性别,种族,但10岁以下较为少见。笔者查阅国内外部份文献,见有2例分别发病于生后2～4个月的报告,而新生儿或先天性恶性淋巴瘤未见报告。因此特将我们新近遇到的二例新生儿恶性淋巴瘤的临床,病理特点作一报告,并对其诊断与鉴别诊断,发病机理、预后等结合文献作重点讨论。 Malignant lymphoma is more common in lymphoid reticular malignancies. It can occur at all ages, genders, and ethnicities, but is less common under the age of 10. The author access to some of the literature at home and abroad, see 2 cases were reported in 2 to 4 months after birth, and no reports of neonatal or congenital malignant lymphoma. Therefore, we have recently encountered two cases of neonatal malignant lymphoma clinical and pathological features as a report, and its diagnostic and differential diagnosis, pathogenesis, prognosis and other documents focused on the literature.
