A, bullous impetigo: mostly occurred in children 2 to 8 years old, occur in the exposed parts, such as head and face, limbs, also can affect the body, for the beginning of erythema or blisters, immediately turned into pustules, rice or soybean, surrounded by flush, blister wall relaxation, blister in pus deposited on the blister bottom. The upper part of the transparent liquid, forming a half moon, blister film rupture after exposing the erosion surface, formed after drying honey yellow pus scab, consciously itching, scratching and easy self contagion to spread around.

Two, pus scab pustulosis: blisters on erythema foundation, immediately turn into pustules, thick pus, inflammation around the flush is obvious, dried honey yellow thick knot scab, scab off about a week or so, and more, do not leave scar.

Impetigo complications: lymphangitis, lymphadenitis, acute nephritis, even septicemia.

Diagnosis: according to the typical skin lesions, age, season is not difficult to diagnose. At the same time for the diagnosis and treatment of pus culture and drug sensitive test assistant.

Neonatal impetigo Impetigo Neonatorum 7

Neonatal severe bullous disease, also called neonatal pemphigus.


Caused by coagulase positive Staphylococcus aureus phage group II type strains, line contact, by the medical staff or nursery families of children with contact and neonatal infection. Due to easy to damage the delicate skin of newborn, immune development is not perfect, or use plastic diapers to make the skin impregnated, would promote the occurrence of the disease, the incidence of acute, highly infectious, easy to cause the baby room, should pay attention to.


In the neonatal morbidity after 4 ~ 10 days, erythema appear in the exposed parts, blisters or bullae, 2-3 days into pustules, blister wall is thin, easy to break, red erosion surface, can be spread to the whole body, dry blisters form a thin crust or scaling, such as invasion and oral mucosa, effect of sucking, light condition but, no systemic symptoms, severe fever, malaise, diarrhea and vomiting, foam green manure, death complicated with nephritis, pneumonia, septicemia, meningitis, etc..


It is easy to diagnose according to age, pathogenesis and clinical features.

Deep pustulosis (Ecthyma)

Commonly known as ecthyma.


It can be caused by Streptococcus pneumoniae and mixed infection with Staphylococcus aureus.


Blisters and pustules appeared in erythema on the basis of the red halos around the obvious inflammation gradually to the deep development, central necrosis, with dark brown crusts as thick as some filthy rupioides, not easy to peel, volcano like ulcer into a scab, with gray green purulent secretions, the formation of scar after healing. Good hair in the lower limbs, buttocks, damage variable number, often several to dozens of nearby lymph nodes, consciousness of local pain, fever, malaise and other symptoms, can be complicated by acute nephritis, toxemia etc..


According to the characteristics of the lesion site and secretion of Streptococcus can be diagnosed.

Differential diagnosis

Impetigo: short duration, damage to blisters, pustules, crusting, no ulceration, no scar after healing.

Prevention and treatment

Two, according to the severity of the disease given various antibiotics or sulfonamides.

Three, local treatment: if there is pus scab available 0.2% nitrofurazone ointment or gentian violet paste such as itching, pustules and erosion surface, adding proper amount of antibiotics available in Zinc Oxide Oil.

Four, ecthyma first with 10% Boric Acid Ointment callus softening, and stimulate the growth of granulation, promote ulcer healing drugs such as Ganshichuangyu powder, ulcer powder etc..

TCM therapy:

Dampness detoxification rule: light with five kinds of disinfection decoction, or with lianqiaobaidu powder.
