| vesicular exanthema | An extinct disease of swine caused by vesicular exanthema virus of swine, a member of the family Caliciviridae; it closely resembled foot-and-mouth disease and, in swine, was characterised by fever, loss of weight, and vesicles on the snout, tongue, and feet. (05 Mar 2000) |

| vesicular exanthema of swine virus | The type species of the genus calicivirus, an RNA virus infecting pigs. The resulting infection is an acute febrile disease which is clinically indistinguishable from foot and mouth disease. Transmission is by contaminated food. (12 Dec 1998) |

| vesicular mole | <gynaecology, oncology, tumour> A relatively rare mass or tumour that can form within the uterus at the beginning of a pregnancy. The cause of hydatidiform mole is unknown. Symptoms include vaginal bleeding, uterine growth, nausea and vomiting. Some hydatidiform moles may become malignant (cancerous) where they are referred to as a choriocarcinoma.

| vesicular ovarian follicle | A follicle in which the oocyte attains its full size and is surrounded by an extracellular glycoprotein layer (zona pellucida) that separates it from a peripheral layer of follicular cells permeated by one or more fluid-filled antra; the theca of the follicle develops into internal and external layers. Synonym: folliculus ovaricus vesiculosus, graafian follicle, secondary follicle. (05 Mar 2000) |
| vesicular rale | A fine bubbling or crackling sound produced by air mixing with very thin secretions in the smaller bronchial tubes. Synonym: vesicular rale. (05 Mar 2000) |
| vesicular resonance | The sound obtained on percussing over the normal lungs. (05 Mar 2000) |
