Urologic Clinics of North America, 1983
Total lymphoid irradiation by itself can produce sufficient immunosuppression to prolong the survival of a variety of organ allografts in experimental animals. The degree of prolongation is dose-dependent and is limited by the toxicity that occurs with higher doses.

Ontogeny of primary lymphoid organs and lymphoid stem cells
American Journal of Anatomy, 1984AbstractCells of the immune system go through a series of important developmental steps that begin early in embryonic life and include, first, the various waves of hemopoietic‐cell production in the embryo and, second, the homing of these cells to the hemopoietic organs, which are the sites of hemopoiesis and lymphopoiesis in embryonic and adult life ...

In children lymphoid polyps of the rectum are uncommon benign lesions with a good prognosis following local treatment. We report a girl in whom a cluster of lymphoid polyps occurred 9 months following removal of a single lymphoid polyp. All of the polyps, including the original lesion, displayed a monoclonal nature on immunocytochemical examination.

Lymphoid organs are integral parts of all vertebrate adaptive immune systems. Primary lymphoid tissues exhibit a remarkable functional dichotomy: T cells develop in specialized thymopoietic tissues located in the pharynx, whereas B cells develop in distinct areas of general hematopoietic areas, such as the kidney or bone marrow.

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.

American Journal of Clinical Pathology, 1993
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 ...

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 ...
