Pseudobacteremia

Pseudobacteremia - discolored spots on the skin at the place of permitted rash at some dermatoses (psoriasis, parapsoriasis, microsporia, herpes pink and others) due to the fact that under the influence of sunlight, the amount of pigment in the skin around the "silo walls" of elements increases, and areas closed from the sun peels and scales, less pigmented. Similar changes are observed in the treatment of psoriasis ointments (hisaronou, signalizoval, psoriasisa)that cause darkening of the surrounding healthy skin. According to the size and shape discolored spots correspond to elements of the former rash. Pseudobacteremia special treatment is not required. Gradually normal colour of the skin is restored.
Cm. also Leucoderma.

Pseudobacteremia (gr. pseudes - false + Leucoderma; false, or secondary, Leucoderma) is one of the forms of pigmentation disorders, characterized by the formation of the bright spots on the background of normal or artificially hyperpigmented skin.
Develops after permission skin rashes eritematosnaya and squamous character (psoriasis, parapsoriasis, pityriasis versicolor, trichophytosis, microsporia, favus, pink zoster, pityriasis alba and others), with streptococcal impetigo, papular syphilis. In size, shape and geometry of pseudobacteremia exactly matches the preceding items rash. Pseudobacteremia often observed in patients with pityriasis versicolor exposed by the sun or a quartz lamp. In these cases, the affected area due to nepremicnine light rays through loosened corneal layer in the depth of the epidermis, and perhaps also because of the delaying action of fungi on the process of pigmentation after the rejection of scales remain bright, sharply standing out against the General background evenly pigmented (tanned) healthy skin [achromia cutis postparasitaria (I.e. Century Kistyakivskyy)]. Pseudobacteremia may develop in patients with psoriasis treated with ointments containing tools that enhance skin pigmentation (prizerebel, pyragollole, psoriasis).
Pseudowintera should be differentiated from the primary true syphilis of leukoderma, characterized correctly rounded shape of the spots, localized, usually on the back and sides of the neck. True solar Leucoderma (see)arising primarily on sites where the light is not there was any visible damage to the skin, very rare.
Pseudobacteremia not require special treatment and disappears as aligned skin pigmentation.
