| lymphoma, large-cell | A form of malignant lymphoma in which the malignant cells resemble histiocytes morphologically but are presently considered to be derived from lymphoid elements. These cells are irregular in shape with relatively abundant, frequently acidophilic cytoplasm. Large-cell lymphoma can occur in both nodular (follicular) and diffuse forms, with the latter being more frequently seen. (12 Dec 1998) |
|---|---|
| lymphoma, large-cell, diffuse | Malignant lymphoma composed of large cells which may be both cleaved and noncleaved. The pattern is predominantly diffuse. most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation. (12 Dec 1998) |
| lymphoma, large-cell, follicular | Malignant lymphoma in which the majority of neoplastic cells within the follicles are large cleaved or noncleaved cells. The degree to which the follicular centre cells retain their ability to form follicles varies with the state of B-cell transformation. (12 Dec 1998) |
| lymphoma, large-cell, immunoblastic | Malignant lymphoma characterised by the presence of immunoblasts with uniformly round-to-oval nuclei, one or more prominent nucleoli, and abundant cytoplasm. This class may be subdivided into plasmacytoid and clear-cell types based on cytoplasmic characteristics. A third category, pleomorphous, may be analogous to some of the peripheral T-cell lymphomas (lymphoma, T-cell, peripheral) recorded in both the united states and japan. (12 Dec 1998) |
| lymphoma, large-cell, ki-1 | A large-cell, non-hodgkin's, malignant lymphoma with pleomorphic appearance and reactivity with the monoclonal antibody ki-1. The lymphoma is most often found in the skin and lymph nodes and expresses the ki-1 (CD30) antigen (antigens, CD30) on its surface. It is often mistaken for metastatic carcinoma and malignant histiocytosis. (12 Dec 1998) |
| accessory gland | A small mass of glandular structure, detached from but lying near another and larger gland, to which it is similar in structure and probably in function. (05 Mar 2000) |
| accessory parotid gland | An occasional islet of parotid tissue separate from the mass of the gland, lying anteriorly just above the commencement of the parotid duct. Synonym: glandula parotidea accessoria, admaxillary gland, glandula parotis accessoria, socia parotidis. (05 Mar 2000) |
| accessory thyroid gland | An isolated mass, or one of several such masses, of thyroid tissue, sometimes present in the side of the neck, or just above the hyoid bone (suprahyoid accessory thyroid gland), or even as low as the arch of the aorta. Synonym: glandula thyroidea accessoria, accessory thyroid, prehyoid gland, suprahyoid gland, thyroidea accessoria, thyroidea ima, Wolfler's gland. (05 Mar 2000) |
| acid gland | One of the gastric gland's secreting the hydrochloric acid of the gastric juice. Synonym: oxyntic gland. (05 Mar 2000) |
| acinotubular gland | A gland whose secretory elements are elongated acini. Synonym: acinotubular gland. (05 Mar 2000) |
| acinous gland | A gland in which the secretory unit(s) has a grapelike shape and a very small lumen; e.g., the exocrine part of the pancreas. (05 Mar 2000) |
| admaxillary gland | An occasional islet of parotid tissue separate from the mass of the gland, lying anteriorly just above the commencement of the parotid duct. Synonym: glandula parotidea accessoria, admaxillary gland, glandula parotis accessoria, socia parotidis. (05 Mar 2000) |
| adrenal gland | <anatomy, endocrinology> This gland is found above each kidney and it made up of an outer wall (cortex) that secretes important steroid hormones and an inner portion (medulla) that produces adrenaline (adrenaline) and noradrenaline (noradrenaline). The hormones help control heart rate, blood pressure, the way the body uses food, and other vital functions. (25 Jun 1999) |
| adrenal gland hypofunction | Adrenocortical hypofunction includes all conditions in which adrenal steroid hormone secretion falls below the requirements of the body. Adrenal insufficiency may be divided into two general categories: (1) those associated with primary inability of the adrenal to elaborate sufficient quantities of hormone and (2) those associated with a secondary failure due to a primary failure in the elaboration of adrenocorticotropin. (12 Dec 1998) |
| adrenal gland insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
