Clinical pictureThis section has been translated automatically.
S.u. Tinea capitis superficialis, tinea corporis, tinea inguinalis, microspore. Starting on smooth skin with an itchy papule around which a pustular focus forms in a ring-shaped zone. When the capillitium is affected, usually the hair follicles are affected and the mycelium grows into the epidermis to a depth of about 0.2 mm. rearrangement of the hair with mycelium, so that infected hair becomes brittle and breaks off easily. Therefore, mechanical epilation is often very difficult. No infestation of the hair bulb.
