UTEROMANIA 



character, and is accompanied by intolerable itching. 

 It is usually seen on the flexor surfaces of the extremi- 

 ties, but may appear on any part of the body, also on 

 the mucous membranes. Domestic animals are also 

 subject to the affection. The poisonous agent secreted 

 by these insects is formic acid. Their influence is 

 said to be either mechanical or chemical, and it is 

 even said that contact is not necessary to its pro- 

 duction. U. evanida, a variety in which there 

 is a rapid disappearance of the symptoms. U. 

 factitia, Dermographia, Autographism, Dermograph- 

 ism, the form produced in individuals with an irri- 

 table skin by any slight external irritation. U. fe- 

 brilis. See U. acuta. U. gigans. See U tuberosa. 

 U. haemorrhagica, Purpura urticans; hemorrhage 

 into the urticarial wheals from rupture of the extremely 

 congested capillaries. U. medicamentosa, that 

 variety resulting from the use of certain drugs. U., 

 Nervous. Synonym of U. factitia. U. cedema- 

 tosa, Giant Urticaria, a variety characterized by 

 the sudden appearance of large , soft, edematous swell- 

 ings of the skin and subcutaneous tissue, which may 

 measure several inches in diameter. These are es- 

 pecially prone to develop about the eyelids, but may 

 also attack the trunk and limbs in the neighbor- 

 hood of the joints. A sense of tension is all that is 

 complained of. If the mucous membrane of the 

 ' throat and larynx is involved the symptoms are 

 alarming but not dangerous. A variety of this is the 

 so-called Quincke's Disease, or acute circumscribed 

 edema, in which the orbital tissue or the tissue of other 

 parts of the face may swell up into a large tumor, or there 

 may be a large, ill-defined swelling of a considerable 

 portion of the limb or other part of the body from subcu- 

 taneous edema (U. subcutanea). It is generally limited 

 to the loins and thighs. U. papulosa, Lichen urti- 



. a form occurring in children, in which, as a re- 

 sult of the inflammatory effusion, a small, solid papule 

 remains after the subsidence of the wheal. It is most 

 abundant about the loins and buttocks, but may appear 

 on any other part of the body. It is often associated 

 with irregular, flat, scabbed pustular lesions. U. pig- 

 mentosa, xanthelasmoidea, a rare type of urticaria, 

 which begins within the first few months of life. It 

 consists of large, reddish, wheal-like tubercles that 

 eventually change to a brownish-red or yellowish 

 color. Itching may or may not be present. The dis- 

 ease runs a protracted course, but tends to spon- 

 taneous recovery at puberty. It is most abundant on 

 the neck and trunk, next upon the limbs, face, and 

 head, and is only occasionally present on the palms and 

 soles. Boys are commonly affected. U., Provoked. 



ivm of U. factitia. U. subcutanea. See 

 U. cedematosa. U. toxica, that due to certain ar- 

 ticles of food. U. tuberosa, U. gigans, a form in 

 which the wheals assume a tuberous form and become 

 very large, as big as a walnut, hen's egg, or even larger. 

 The lesions are few in number, and the disease occurs 

 mainly in persons with broken-down constitutions, 

 beyond middle age. See Angio-neurotic edema. U. 

 vesicans, excessive serous effusion into the center of 

 the wheals, producing vesicles. U. vesiculosa. Same 

 as L . papulosa.
