| lymphangioma capillare varicosum | A congenital nevoid lesion consisting of a circumscribed group of tense lymph vesicles. Synonym: lupus lymphaticus, lymphangiectodes, lymphangioma capillare varicosum, lymphangioma superficium simplex. (05 Mar 2000) |
| lymphangioma cavernosum | A condition of conspicuous dilation of lymphatic vessels in a fairly circumscribed region, frequently with the formation of cavities or "lakes" filled with lymph. Synonym: cavernous lymphangiectasis. (05 Mar 2000) |
| lymphangioma circumscriptum | A congenital nevoid lesion consisting of a circumscribed group of tense lymph vesicles. Synonym: lupus lymphaticus, lymphangiectodes, lymphangioma capillare varicosum, lymphangioma superficium simplex. (05 Mar 2000) |
| lymphangioma, cystic | A lymphangioma, often very large, usually occurring in the neck area, and composed of large, multilocular thin-walled cysts. It is also called hygroma or cystic hygroma. (12 Dec 1998) |
| lymphangioma cysticum | A condition characterised by a fairly well circumscribed group of several or numerous, cystlike, dilated vessels or spaces lined with endothelium and filled with lymph. Synonym: cystic lymphangiectasis. (05 Mar 2000) |
| lymphangioma simplex | A circumscribed region or focus of several to numerous lymphatic vessels that are moderately dilated. Synonym: simple lymphangiectasis. (05 Mar 2000) |
| lymphangioma superficium simplex | A congenital nevoid lesion consisting of a circumscribed group of tense lymph vesicles. Synonym: lupus lymphaticus, lymphangiectodes, lymphangioma capillare varicosum, lymphangioma superficium simplex. (05 Mar 2000) |
| lymphangioma tuberosum multiplex | A cutaneous lesion characterised by multiple, slightly red, cystlike nodules (located chiefly on the trunk), resulting from fairly large lymphatic vessels and spaces, and groups of proliferating endothelial cells; the lesion has some gross resemblance to spiradenoma, except for the characteristic location. (05 Mar 2000) |
| lymphangioma xanthelasmoideum | A capillary lymphangioma with colloid degeneration of the elastic tissues of the skin, characterised by yellow-brown or gray-brown plaques that may be only slightly raised above the surface of the skin. (05 Mar 2000) |
| arterial capillary | A capillary opening from an arteriole or metarteriole. (05 Mar 2000) |
| bile capillary | One of the intercellular channels, about 1 um or less in diameter, that occurs between liver cells forming the first portion of the bile system. Synonym: bile capillary. (05 Mar 2000) |
| blood capillary | A vessel whose wall consists of endothelium and its basement membrane; its diameter, when the capillary is open, is about 8 um; with the electron microscope, fenestrated capillary's and continuous capillary's are distinguished. (05 Mar 2000) |
| capillary | <anatomy> Any one of the minute vessels that connect the arterioles and venules, forming a network in nearly all parts of the body. Their walls act as semipermeable membranes for the interchange of various substances, including fluids, between the blood and tissue fluid. Synonym: vas capillare. Origin: L. Capillaris = hair like (16 Dec 1997) |
| capillary action | The phenomenon of a liquid such as water spontaneously creeping up thin tubes and fibres, this is caused by adhesive and cohesive forces and surface tension. (09 Oct 1997) |
