NAS'VUS MATER'NUS, one of thofe little fpots, ex- 
erefcences, or fyyellings, with which many children are 
born. There are two kinds; viz. fmall red tumours, 
which gradually increafe to a large fize ; and brown flat 
marks, not rifing in the leaft above the furface of the Ikin. 
Mr. Latta fays, he once favv in a child two years old, a 
tumour of this kind weighing fourteen ounces, which, at 
the time of birth, was only equal in fize to a large bean, 
and which, for a year afterwards, did not enlarge much ; 
but then grew to the magnitude already fpecified. The 
other fpecies, or l’uch as rife but little above the Ikin, are 
of various forms, and have been compared with cherries, 
grapes, &c. and have all been luppofed to arife fromfome 
impreffion made on the mind of the mother during preg¬ 
nancy, or at the time of conception. 
Thofe navi mat find which are mere fpots, or marks, 
give no inconvenience, and of courfe do not require the 
interference of furgery. But fuch as elevate themfelves 
above the furface of the body, increafe in fize, and feem 
likely to become troublefome, fhould be entirely removed 
with a knife. Many of them feem to confift of a conge¬ 
ries of dilated velfels, and, after they have acquired a cer¬ 
tain fize, are apt to burft, and bleed profufely. Mr. John 
Bell has named this kind of difeafe uneurifm by anajlomojis. 
The difeafe originates from fome accidental caufe ; is 
marked by a perpetual throbbing ; grows flowly, but un- 
controulably; and is rather irritated than checked by com- 
preflion. The throbbing is at firft indiltinft, but, when 
the tumour is perfectly formed, the pulfation is very ma- 
nifell. Every exertion makes the throbbing more evi¬ 
dent. The occafional turgid ftates of the tumour pro¬ 
duce facs of blood in the cellular fubftance, or dilated 
veins ; and thefe facs form little tender, livid, very thin, 
points, which burft from time to time, and then, like 
other aneurifms, this one bleeds fo profufely, as to induce 
extreme weaknefs. The tumour is a congeries of adtive 
veflels; and the cellular fubftance, through which thefe 
veflels are expanded, refembles, as Mr. John Bell defcribes, 
the gills of a turkey-cock, or the fubftance of the pla¬ 
centa, fpleen, or womb. The irritated and inceflant ac¬ 
tion of the arteries fills the cells with blood, and from 
thefe cells it is re-abforbed by the veins. The fize of the 
fwelling is increafed by exercife, drinking, emotions of the 
mind, and by all caufes which accelerate the circulation. 
Mr. Bell ftates, that all attempts to obliterate the 
difeafe with cauftics, after a ninple incifion, have proved 
unfuccefsful, nor does the interrupting of particular vef- 
fels, which lead to it, affedf the tumour; the whole 
group of veflels muft be extirpated. John Bells Principles 
of Surgery, vol. i. 
Mr. Abernethy cured a nsevus maternus upon a child’s 
arm by means of prefiure with a bandage. A tumour of 
the fame nature, fituated in the orbit, and caufing a dil- 
placement of-the eye, violent headachs, &c. was cured by 
tying the carotid artery of the fame fide. Medico-chirurg.
