Dilated, blackish follicular openings (pseudocomedones) with dark stained spine. Expression of the follicular filament is possible.
HistologyThis section has been translated automatically.
Dilated distended hyperkeratotic infundibulum with a mantle of corneocytes. Bundles of short lanugo hairs (10-50 lanugo hairs) and a single associated hair root (assignment recognizable in serial incisions). No perifollicular inflammatory reaction! The growth of two hairs from one hair follicle is called districhiasis.
Differential diagnosisThis section has been translated automatically.
TherapyThis section has been translated automatically.
A treatment is only necessary for cosmetic reasons. Mechanical squeezing of the follicle filaments with a comedone squeezer by a medical cosmetician. Quickly polymerising cyanoacrylate adhesives (superglue) are useful for removal, with the help of which the superficial layers of the horny layer together with the associated follicle retentions can be peeled off. Supportive therapy with vitamin A acid-containing topicals such as isotretinoin (e.g. Isotrex cream/gel, 1-2 times/day) or tretinoin (e.g. Cordes VAS cream, 1-2 times/day) or glycolic acid-containing topicals (e.g. Eff-alpha, Neostrata AHA solution/cream 1 time a day). However, the success is only moderate. In case of persistent therapy-resistant processes try chemical peeling with glycolic acid.
