Follicular lymphoma presenting like marginal zone lymphoma: A case report.

Background: Follicular lymphoma (FL), a common type of indolent lymphoma, carries markers of the germinal center, and the rearrangement of the gene is regarded as an initiating event and a hallmark of the neoplasm. When FL has marginal zone differentiation, some marginal zone features are carried by the neoplasm.

Case Summary: A 54-year-old male with lymphadenopathy, splenomegaly and hyperlymphocytosis was diagnosed with FL with marginal zone differentiation.

[Simultaneous determination of aflatoxin B_1,B_2,G_1,G_2,M_1,M_2 in Eupolyphaga Steleophaga by immunoaffinity column clean-up and HPLC-FLD with post-column photochemical derivatization].

The contamination of aflatoxin B_1,B_2,G_1,G_2,M_1 and M_2 in Eupolyphaga Steleophaga was determined by immunoaffinity column clean-up and HPLC-FLD with post-column photochemical derivatization. Chromatographic separations were carried out using a Cloversil C_(18) column( 4. 6 mm×250 mm,5 μm) that were eluted in isocratic with methanol-acetonitrile-water( 20 ∶ 20 ∶ 60) as the mobile phase.
