: 1. A pigmented spot on the skin (nevus). 2. A mass within the uterus (womb) formed by partly developed products of conception.

1. SYN: nevus (2). 2. SYN: nevus pigmentosus. [A.S. mael (L. macula), a spot] 3. An intrauterine mass formed by the degeneration of the partly developed products of conception. [L. moles, mass] 4. (mol) In the SI system, 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 m. is 6.0221367 × 1023 “elementary entities.” SEE ALSO: Avogadro number.
- carneous m. SYN: fleshy m..
- cystic m. SYN: hydatidiform m..
- fleshy m. a uterine mass occurring after fetal death and consisting of blood clots, fetal membranes, and placenta. SYN: carneous m..
- hairy m. SYN: nevus pilosus.
- hydatidiform m., hydatid m. [MIM*231090] a vesicular or polycystic mass resulting from the proliferation of the trophoblast, with hydropic degeneration and avascularity of the chorionic villi; the abnormal tissue typically results from expression of paternally derived chromosomes and a loss of maternal chromosomes. SYN: cystic m., gestational trophoblastic disease.
- invasive m. SYN: chorioadenoma destruens.

mole 'mōl n a pigmented spot, mark, or small permanent protuberance on the human body esp NEVUS
mole n an abnormal mass in the uterus:
a) a blood clot containing a degenerated fetus and its membranes
mole also mol 'mōl n the base unit in the International System of Units for the amount of pure substance that contains the same number of elementary entities as there are atoms in exactly 12 grams of the isotope carbon 12 <a \mole of photons> <a \mole of sodium chloride>

Ⅰ. n.
a nonmalignant collection of pigmented cells in the skin. Moles are rare in infancy, increase in numbers during childhood and especially in adolescence, but decline in numbers in old age. They vary widely in appearance, being flat or raised, smooth or hairy. Changes in the shape, colour, etc., of moles in adult life should be investigated as this may be an early sign of malignant melanoma. Medical name: pigmented naevus. See also atypical mole syndrome.
Ⅱ. n.
the SI units of amount of substance, equal to the amount of substance that contains as many elementary units as there are atoms in 0.012 kilograms of carbon-12. The elementary units, which must be specified, may be atoms, molecules, ions, electrons, etc., or a specified group of such entities. One mole of a compound has a mass equal to its molecular weight expressed in grams. Symbol: mol.

(mol) (mōl) [Ger. Mol, short for Molekulargewicht molecular weight] the base SI unit of amount of matter, being that amount of substance (in a system) that contains as many elementary entities (e.g., atoms, ions, molecules, or radicals) as there are carbon atoms in 0.012 kg of carbon 12 (12C); thus one mole equals 6.023 Ч 1023 (Avogadro's number) elementary entities. Formerly, the connotation of mole was gram molecular weight (q.v.) and the two terms were sometimes used synonymously.
