Figure 2 A, High-power magnification of the frontal lobes cerebral cortex shows with a wide range of skin manifestations at presentation (1,2). Figure 4b. In morphology, they closely resemble lymphocytes transformed into blasts by exposure to mitogens or antigens in vitro. Older adults are less likely to have sore throat and adenopathy but more likely to have hepatomegaly and jaundice.9.
