| follicular papule | <dermatology> A papular lesion arising about a hair follicle. It is a feature that is not specific for any condition. (05 Mar 2000) |
|---|---|
| follicular phase | <gynaecology, physiology> The follicular phase is the pre-ovulatory phase of a woman's reproductive cycle during which the follicle grows and high oestrogen levels cause the uterine lining to grow. (09 Oct 1997) |
| follicular predominantly large cell lymphoma | <tumour> A B-cell lymphoma of intermediate malignancy. (05 Mar 2000) |
| follicular predominantly small cleaved cell lymphoma | <tumour> A B-cell lymphoma with nodular or diffuse lymph node or bone marrow involvement by large lymphoid cells. Synonym: follicular predominantly small cleaved cell lymphoma, nodular histiocytic lymphoma. (05 Mar 2000) |
| follicular stigma | <gynaecology, physiology> The point where the graafian follicle is about to rupture on the surface of the ovary. Synonym: macula pellucida, stigma. (05 Mar 2000) |
| follicular syphilid | Secondary eruption of small follicular papules, usually appearing as groups of lesions. Synonym: acuminate papular syphilid, lichen syphiliticus, miliary papular syphilid. (05 Mar 2000) |
| follicular trachoma | <ophthalmology> The ordinary form of trachoma marked by the presence of granulations on the conjunctiva. Synonym: granular trachoma. (05 Mar 2000) |
| follicular urethritis | <urology> Chronic urethritis with nodular lymphocytic infiltrations in the mucosa. Synonym: granular urethritis. (05 Mar 2000) |
| follicular vulvitis | <gynaecology> Inflammation of the vulvar follicles. (05 Mar 2000) |
| lymphoma, follicular | Malignant lymphoma in which the lymphomatous cells are clustered into identifiable nodules within the lymph nodes. The nodules resemble to some extent the germinal centres of lymph node follicles and most likely represent neoplastic proliferation of lymph node-derived follicular centre B-lymphocytes. This class of lymphoma usually occurs in older persons, is commonly multinodal, and possibly extranodal. Patients whose lymphomas present a follicular or nodular pattern generally have a more indolent course than those presenting with a diffuse pattern. (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, mixed-cell, follicular | A low-grade malignant lymphoma of follicular pattern in which there is no clear preponderance of one cell type (small or large) over another. The large cells, cleaved or noncleaved, are often 2-3 times larger in diameter than normal lymphocytes. (12 Dec 1998) |
| lymphoma, small cleaved-cell, follicular | A low-grade malignant lymphoma of predominantly follicular pattern. Follicles are of relatively uniform size and shape and the cells are usually somewhat larger than normal lymphocytes. Nuclei are irregular with prominent indentations and cytoplasm can rarely be identified. Cells exhibiting these characteristics are often called centrocytes. (12 Dec 1998) |
| A layer | <molecular biology> Right handed double helical DNA with approximately 11 residues per turn. Planes of base pairs in the helix are tilted 20 deg away from perpendicular to the axis of the helix. Formed from B DNA by dehydration. (18 Nov 1997) |
| ameloblastic layer | The internal layer of the enamel organ. Synonym: enamel layer. (05 Mar 2000) |
