4. In the SI, the unit of amount of substance, defined as that amount of a substance containing as many "elementary entities" as there are atoms in 0.0120 kg of carbon-12; "elementary entities" may be atoms, molecules, ions, or any describable entity or defined mixture of entities and must be specified when this term is used; in practical terms, the mole is 6.0221367 × 1023 "elementary entities."

mole

Chemistry
The number of grams equal to a chemical’s formula weight, an element’s atomic weight, or a compound’s molecular weight.
 
Dermatology
A nonspecific lay term for any pigmented lesion, benign or malignant.

Obstetrics
(1) Hydatidiform mole, see there.
(2) Complete mole. The chorionic villi are swollen, often accompanied by trophoblastic proliferation but not foetal tissue. CMs are 10–20 times more common in Southeast Asia, and demonstrate innumerable grape-like avascular chorionic villi. Most CMs have a 46 XX genotype, of which both X chromosomes are of paternal origin; in 10–15% of the complete moles that are 46 XY, both the X and Y chromosomes are of paternal origin. CMs may be due to abnormal gametogenesis and fertilisation: while in 46 XX moles there is fertilisation of an empty ovum with no effective genome by a haploid sperm that duplicates without cytokinesis, in the 46 XY complete moles there may be fertilisation of an empty ovum by two haploid sperm with subsequent fusion and replication. 
(3) Partial mole. A mass characterised by a mixture of foetal tissue with normal oedematous villi and/or hydropic degeneration. Most partial moles are triploid (47 XXY > 47 XXX, > 47 XYY), rarely also trisomy 16, and may be the result of unsuccessful dual fertilisation of a single ovum; the conceptus does not die, but remains as a proliferating “tumour”. 
(4) Invasive mole. A trophoblastic proliferation that penetrates the myometrium and may undergo malignant degeneration into a choriocarcinoma.

MOLES
A birthmark or nevus. See: illustration

CAUTION!

Moles should be examined and, if necessary, be removed by experienced professionals.

Patient care

The patient is encouraged to regularly inspect areas of the skin that have moles and consult a health care professional about any mole that changes color or shows signs of growth or changes in appearance, as such changes may indicate neoplasm.

pigmented mole

Nevus pigmentosus.

vascular mole

Hemangioma.illustration

2 mole

, mol (mōl) [Ger. Mol, abbr. for Molekulargewicht, molecular weight]
In the Système International d’ Unités (SI system), 1 mole of a substance contains as many atoms as exist in 0.012 kg of carbon 12.

3 mole

(mol) [L. moles, a shapeless mass]
A uterine mass arising from a poorly developed or degenerating ovum.

blood mole

A mass made up of blood clots, membranes, and placenta, retained after fetal death.

Breus mole

See: Breus mole

carneous mole

A uterine mass that consists of clotted blood and remnants of the placenta and fetal membranes. It may be retained in the uterus for many months after a miscarriage or missed abortion. Synonym: fleshy mole

false mole

A mole formed from a uterine tumor or polypus.

fleshy mole

Carneous mole.

hydatid mole

A rare form of gestational trophoblastic disease in which there is overproduction of chorionic villi normally destined to develop into the placenta. A partial mole is characterized by an abnormal placenta and some fetal development; a complete mole, by an abnormal placenta and no fetal development. Complete and partial moles differ in karyotype. Complete moles show an absence of maternal chromosomes and a duplication of spermatozoal chromosomes. Partial moles exhibit either karyotype 69 XXY or karyotype 69 XYY due to the presence of the maternal X chromosome. Symptoms of molar pregnancy may include abnormal uterine growth (usually increased), nausea and vomiting, vaginal bleeding, and high blood pressure. Diagnosis is made by measuring serum human chorionic gonadotropin levels and ultrasonography, and definitive treatment is complete surgical removal of the mole, usually with curettage. Moles that are not removed may become malignant. Eighty percent of all moles are benign. See: gestational trophoblastic disease

stone mole

A fleshy mole that has undergone calcific degeneration in the uterus.

true mole

A mole representing the degenerated embryo or fetus.

vesicular mole

Hydatid mole.

mole

1. A coloured (pigmented) birth-mark (naevus). Hairy moles may be disfiguring but are never dangerous. Moles seldom undergo malignant change, but any alteration is size, shape or colour should be reported at once. Moles are easily removed under local anaesthesia. From the Latin mola , a millstone. See also MALIGNANT MELANOMA.
2. The basic unit of amount of substance; the amount that contains the same number of entities as there are atoms in 0.012 kg of carbon-12. The entity may be an atom, a molecule, an ion, and so on. From the German molekül , a molecule.

mole

the basic SI unit of amount of substance. One mole of any substance contains 6.023 × 1023 (Avogadro's number) molecules, atoms or ions of an element or compound equal to the relative molecular mass in grams. Symbol: mol.

Mole

A mass of abnormal, partially developed tissues inside the uterus (womb). Moles develop during a pregnancy that begins with an abnormal fertilization.

Patient discussion about mole

Q. How can you know if a mole is a skin cancer or not? I'm only 15, but I’ve had this small thing on my right shoulder for a reeeeaaaally long time. It's the same color as my skin. It’s smaller than the head of a pencil eraser, perfectly round, and its smooth. I've never worried about it seriously, until about a week ago, when I read an article in a magazine about skin cancer. Even then I wouldn't have worried about it, because It didn't really match any of the symptoms, except one. It did bleed once about 2 1/2 years ago. And it said bleeding was a big sign I don't know, what do you think? And please try and say something other than," go have it checked out". Because I currently have no insurance. Thanks :]

A. If I’m not mistaken- there are clinics that do free checkups for skin cancer. I know that in my town there are couple. Here is a link I got when I googled “do free checks for skin cancer”:
http://skinsurgeryclinic.co.nz/free.htm
look for one near your home.

Q. My husband has a very small mole that was cut.We can not seem to get it to stop bleeding. Any suggestions? tried a shaving pencil, and band-aids of every size. Just will not stop bleeding.

A. In this case, you should go see the doctor who took the mole out, or any dermatologist actually, that can burn the spot a little bit to help it stop bleeding.
