Pemphigus {pern' -fig-us) [tzejx^, a blister]. Pom* 

 pholyx ; Bladder-tetter ; an inflammatory disease of 

 the skin characterized by the formation of variously- 

 sized blebs that appear in successive crops, occasionally 

 also on the mucous membranes. The acute form is 

 contagious and is most frequent in infants (P. neona- 

 torum) ; in adults recovery may take place, although 

 there is an acute form that sometimes proves fatal. 

 The acute form of the disease seems to be infectious ; 

 microorganisms, especially a diplococcus, have been 

 found in the fluid of the blebs. Some cases of pem- 

 phigus appear to be neurotic in origin. P. acutus, 

 the acute form of the disease. P. benignus. See P. 

 vulgaris. P. cachecticorum, P. cachecticus, 

 pemphigus occurring in cachectic persons. P. chron- 

 icus. See P. vulgaris. P. circinatus. See Ily- 

 droa herpetiforme . P. contagiosus, Epidemic Pem- 

 phigus ; a variety that occurs in epidemics, invariably 

 in children. P. contagiosus tropicus, an epidemic 

 form occurring only in the tropics, and appearing in a 

 diffuse or infantile and an axillary or adult form. P.

 at the bases of the blebs. P. diutinus. See P. vul- 

 garis. P., Epidemic. See P. contagiosus. P. foli- 

 aceus, a rare form in which the blebs are flaccid, with 

 puriform contents, and soon rupture. The disease 

 spreads slowly but surely, and the whole body even- 

 tually becomes involved. The mucous membranes 

 may also be affected. The patient usually dies in an 

 exhausted typhoid condition. P. gangraenosus, a 

 variety in which the inflammatory process is intense 

 and superficial, or deep sloughs form. See also Der- 

 matitis gangrcenosus infantum. P. gyratus, pemphi- 

 gus in which the blebs are arranged in circular lines. 

 P. haemorrhagicus, Purpura bullosa ; pemphigus 

 attended with hemorrhage into the bullae, varying 

 in amount from enough to impart a mere pink 

 tint to the serum up to black. P. hystericus. 

 See P. pruriginosus. P. leprosus, the bullous 

 eruption of leprosy. P. localis. See P. solitarius. 

 P. major. Synonym of P. vulgaris. P. malig- 

 nus. See P. pruriginosus. P. medicamentosus, 

 pemphigus due to the administration of a drug. 

 P. neonatorum. See Pemphigus. P. pruriginosus, 

 a form associated with severe itching, purulent con- 

 tents of the bullae, and the appearance of wheals. 

 From the scratching, eczema, ecthyma and other forms 

 of dermatitis are produced. The patient becoim 

 hausted from loss of sleep, and a fatal issue may result. 

 The affection is also called Pemphigus malignus, J/v- 

 droa herpetifonne, Pemphigus hystericus. P. puerper- 

 alis, pemphigus occurring in puerperal women, it 

 may be associated with puerperal infection. Some 

 have been considered forms of Duhring's disease, der- 

 matitis herpetiformis. P. scorbuticus, the blebs or 

 the blood-stained serum that sometimes appear over 

 hemorrhagic areas in scurvy. P. solitarius, pemphi 

 gus localis; a form in which the blebs are single 

 or few in number, localized in distribution, an 

 companied by little constitutional disturbance. 1 hey 

 occur where the circulation is feeble, as on tin 

 fingers, or nose. They are chiefly seen in tin 

 and debilitated. P. syphiliticus, the bullous erup- 

 tion of syphilis, most common in the syphilitic new- 

 born. P. vegetans, an extremely rare form, the
