Purpose: To elucidate MRI features of primary hepatic mucosa-associated lymphoid tissue (MALT) lymphoma, particularly, the “speckled enhancement” on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI.

An 11 year – old mixed female Labrador was presented with two masses in trunk and neck. The tumoral masses were excised and sent for histopathological and immunohistochemical analyses. Histopathological examination of masses revealed diffuse infiltration of small sized lymphoid cells in subcutaneous tissue which were intense around the blood vessels. More than 10% lymphoid cells were CD3 positi...

Acute lymphoblastic leukaemia (ALL) is a malignant transformation of a clone of cells from lymphoid progenitor cells. The majority of cases are of B-cell origin but it can also arise from T-cell precursors. Lymphoid precursors proliferate and replace the normal cells of the bone marrow and blasts spill into the peripheral circulation. It can be distinguished from other malignancies of lymphoid ...

patches of man, initiates and controls another lymphoid differ entiation pathway directed toward the plasma cell and immunoglobulin production. Thymus-dependent and bursa-dependent lymphocytic malignancies have been defined in the mouse and chicken, respectively, and are featured by abnormal Lymphoid differentiation beginning in one or the other central lymphoid organ. It is proposed that clini...

Ectopic expression of CC chemokine ligand 21 (CCL21) in the thyroid leads to development of lymphoid structures that resemble those observed in Hashimoto thyroiditis. Deletion of the inhibitor of differentiation 2 (Id2) gene, essential for generation of CD3-CD4+ lymphoid tissue-inducer (LTi) cells and development of secondary lymphoid organs, did not affect formation of tertiary lymphoid struct...
