Fennel grooved. Fennel is widely cultivated, both in its native range and elsewhere, for its edible, strongly flavored leaves and fruits. Its aniseed flavor comes from anethole, an aromatic compound also found in anise and star anise, and its taste and aroma are similar to theirs, though usually not as strong. Florence fennel ("Foeniculum vulgare" Azoricum Group; syn. "F. vulgare" var. "azoricum") is a cultivar group with inflated leaf bases which form a bulb-like structure. It is of cultivated origin, and has a mild anise-like flavor, but is sweeter and more aromatic. Florence fennel plants are smaller than the wild type.
Nodular lymphocyte predominant Hodgkin's lymphoma composed of vague nodules of numerous reactive lymphocytes admixed with large popcorn-shaped RSC. Unlike classic RSC, the non-classic popcorn-shaped RS cells of NLPHL are CD15 and CD30 negative while positive for the B cell marker CD20. The anti-CD20 monoclonal antibody Rituximab has been used in lymphocyte predominant Hodgkin's lymphoma with encouraging results. BCL6 gene rearrangements have been frequently observed. The characteristics of NLPHL differ from classical Hodgkin lymphoma (cHL). Lymphocyte predominant (LP) ("popcorn") cells are present embedded in nodules consisting of B cells and other reactive cells (mainly reactive T cells). Reed-Sternberg and Hodgkin (RSH) cells are rarely seen, and
