Small-bulb impetigo, non-bullous impetigo.
The non-bullous form is more common than the bullous variant. Usually staphylococci are the trigger, sometimes there is a mixed infection or colonisation with group A streptococci.
Macular erythematous lesions with severe exudation and honey-yellow crusts are seen mainly on the face, especially under the nose, but also in other locations (neck, trunk, hands, etc.). In addition, tense, water-clear vesicles are visible. Often, no primary florescences can be identified. In the course of the disease, healing occurs without scarring.>
- Clinical presentation
- Bacterial smear
- ASL titer, ASO titer
- Urinanalysis (to rule out glomerulonephritis), follow-up after 2-4 weeks recommended
- In adults, HIV infection should be excluded
Mostly on the face, especially under the nose, but also in other locations (neck, trunk, hands, etc.).
Spongiosis and subtle inflammatory reaction of the deeper epithelium. Subcorneal pustule formation (bacteria, fibrin and neutrophil leukocytes).
- Purulent conjunctivitis
- Otitis media
- Postinectic glomerulonephritis
- Rheumatic fever
