EtiopathogenesisThis section has been translated automatically.
Infection of the hair follicle by Staphylococcus aureus.
- Microtrauma, e.g. by shaving (beard region and lower leg)
- Moist maceration, moist warm intertriginous areas, sweating, treatment of certain skin areas that are too oily or too moist, plastic occlusion dressing.
- Faulty occluding clothing in warm and humid climate
- Defensive weakness.
- Itchy scratched skin diseases
ManifestationThis section has been translated automatically.
Occurrence possible at any age, but especially in infancy and toddlers. No gender dominance.
LocalizationThis section has been translated automatically.
Especially face, cheeks, nose, armpits, extremities, lower legs after shaving. In principle possible on the whole integument where occlusion is caused by clothing or by close contact.
Clinical featuresThis section has been translated automatically.
Acutely occurring, solitary or multiple, punctiform (follicularly bound), also grouped, 0.1-0.2 cm large, flat, red papules or yellow-red papulo-pustules with a discreet red border. The follicular inflammations are often pierced by a central hair. This finding is easily recognizable in the case of an infestation of terminal hair follicles (Note: only the clear follicular infestation defines the diagnosis! If vellus hair regions are affected (e.g. trunk), the relation to the follicle is not always clearly evident).
The superficial folliculitis does not exceed the follicular border. There is no perifollicular abscess formation (boils).
There is a slight painfulness of the single folliculitis, if necessary also of the region, but more often itching. After approx. 5 days drying out and formation of a yellow-brown crust. Complete healing without scarring. Recurrences are frequent if the cause is not eliminated.
HistologyThis section has been translated automatically.
