ABSTRACT
We report the case of a 54 year old male with an original diagnosis of chronic myeloid leukemia (CML) who developed a nodal T cell blast crisis (BC) while he was in a complete hematological remission (CR). We describe the clinical presentation and the histological, immunophenotypic and molecular characterization of the lymph node blast cells. Our case, together with other rare similar reports in the literature, argue that a T cell nodal blast crisis of CML resembles the presentation of a T-cell non-Hodgkin's lymphoma.

Homogenates of left ovaries from laying hens incubated with labeled pregnenolone or progesterone produced slightly higher amounts of estrone than of estradiol-17 beta. Progesterone, 17 alpha-hydroxyprogesterone, androstenedione and testosterone are probable intermediates. Left ovaries from 1-, 21- and 40-days-old chicks incubated with progesterone as substrate formed increasing amounts of androgens and estrogens. Weight per weight, ovaries from one-day-old chicks have a greater steroidogenic capability than those from adults. The comparative steroidogenesis by testes and left ovaries from Gallus domesticus during growth is also reported.
