摘要: Most lymphoblastic lymphomas of the mouse appear to originate in thymus, though not necessarily from thymic lymphocytes (see Etiology and Pathogenesis). The initial gross lesion is reduction size (thymic atrophy). Subsequently, one lobe enlarges by nodular lymphomatous infiltration which spreads progressively involve entire organ. At this time, thymus may measure up 1 cm diameter, yet also unremarkable thymuses can be entirely replaced leukemic cells (Fig. 282). organ pale-pink color, has a fish flesh appearance, friable. Subsequently enlarged lymph nodes exhibit similar changes.
