| hydatidiform mole, invasive | A tumour or tumour-like process invading the myometrium, and characterised by trophoblastic hyperplasia and persistence of placental villous structures. It commonly results from complete hydatidiform mole but may do so from partial hydatidiform mole. Invasive mole may metastasize but it does not exhibit the progression of a true cancer, and it may regress spontaneously. (holland et al., cancer medicine, 3d ed, p1691) (12 Dec 1998) |

| surgical procedures, minimally invasive | Procedures that avoid use of open invasive surgery in favour of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device. With the reduced trauma associated with minimally invasive surgery, long hospital stays may be reduced with increased rates of short stay or day surgery. (12 Dec 1998) |
| invasive | 1. Having the quality of invasiveness. 2. Involving puncture or incision of the skin or insertion of an instrument or foreign material into the body, said of diagnostic techniques. (18 Nov 1997) |
| invasive cancer | Cancer that has spread to surrounding tissue. (16 Dec 1997) |
| invasive carcinoma | <tumour> A neoplasm in which collections of epithelial cells infiltrate or destroy the surrounding tissue. (05 Mar 2000) |
| invasive cervical cancer | Cancer that has spread from the surface of the cervix to tissue deeper in the cervix or to other parts of the body. (12 Dec 1998) |
| invasive species | Non-native species disrupting and replacing native species. (09 Oct 1997) |
| blood mole | A uterine mass occurring after foetal death and consisting of blood clots, foetal membranes, and placenta. Synonym: blood mole, carneous mole. (05 Mar 2000) |
| Breus mole | An aborted ovum in which the foetal surface of the placenta presents numerous haematomata with an absence of blood vessels in the chorion and an ovum much smaller in size than normal in relation to the duration of the pregnancy. (05 Mar 2000) |
| carneous mole | A uterine mass occurring after foetal death and consisting of blood clots, foetal membranes, and placenta. Synonym: blood mole, carneous mole. (05 Mar 2000) |
| malignant mole syndrome | <syndrome> Irregularly shaped, variously coloured, distinctively melanocytic, 5 to 10 mm nevi occurring in large numbers (to over 100) primarily on the trunk and extremities, with a high risk of malignancy reported in several members and three generations of a family. (05 Mar 2000) |
| 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. Incidence: 1 in 1,500 births. (02 Jan 1998) |
| grape 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. Incidence: 1 in 1,500 births. (02 Jan 1998) |
| mole | <dermatology> A benign pigmented skin lesion or nevus. (27 Sep 1997) |
| mole fraction | The ratio of the moles of one component of a system to the total moles of all the components present. (05 Mar 2000) |
