Lymphoid Interstitial Pneumonia and Other Benign Lymphoid Disorders
Seminars in Respiratory and Critical Care Medicine, 2016Benign pulmonary lymphoid disorders include a variety of rare lymphoid abnormalities characterized by a polyclonal lymphoid infiltrate with differing histopathologic patterns and clinicoradiologic features that may overlap. Histological examination is essential to reach a correct diagnosis and to exclude alternative causes, although this task can at ...

Organization of the Invading Lymphoid Tissue in Human Lymphoid Thyroiditis
Scandinavian Journal of Immunology, 1974The structural pattern of lymphoid tissue in lymphoid thyroiditis was analyzed by thin‐section histology in ten thyroidectomy specimens representing focal and massive thyroiditis. Special attention was devoted to the identification of high‐endo‐thelium postcapillary venules, which were found in eight cases, they were absent only in two of the ‘focal ...

Lymphoid Polyps (Focal Lymphoid Hyperplasia) of the Colon in Children
Pediatrics, 1982Lymphoid polyps (focal lymphoid hyperplasia) of the colon are rare in children. These lesions are benign, but must be differentiated from malignant lymphomas. Grasp biopsies of the lesion are inadequate for this purpose and the polyp should be submitted in toto for pathologic examination. No treatment other than local excision is warranted.

Lymphoid lesions of the parotid
Diagnostic Cytopathology, 1999Lymphoid lesions of the parotid gland are much less common than their epithelial counterparts, and thus cytologic experience on fine-needle aspiration (FNA) is limited. FNA of lymphoid lesions with ancillary aids (flow cytometry and immunophenotypic studies) can make a definitive diagnosis.

Endocytosis of CD4 in Lymphoid and Non-Lymphoid Cells
1992The lymphoid differentiation antigen CD4 is a glycoprotein which binds to non-polymorphic regions on MHC class II molecules and is expressed primarily on helper/inducer T-lymphocytes and on some cells of the macrophage/monocyte lineage. CD4 is involved in T-cell ontogeny in the thymus and in the activation of peripheral blood lymphocytes (Robey and ...

Lymphomas that involve extranodal sites generally are divided into two classifications:primary and secondary extranodal lymphomas. They are relatively common, representing from 10-40% of non-Hodgkin's lymphomas. 1-3 Primary extranodal lymphomas are defined as localized lymphomas that appear or originate in extranodal tissues, with or without ...

For researchers interested in cell-based therapy, it is a great challenge to learn how to expand lymphoid cells and their precursor cells ex vivo under defined conditions. Lymphocytes are defined by their cell surface receptor – BCR (B Cell Receptor, or immunoglobulin, Ig) for B cells and TCR (T Cell Receptor) for T cells.

The organs included in this chapter include the thymus, lymph nodes, spleen, and bone marrow. The main responses seen in these organs are due to immunostimulation, immunosuppression, immunogenicity, or hypersensitivity. The changes in lymphoid organs are subject to many environmental factors.
