Tinea capitis profunda B35.02

Inflammatory maximum variant of tina capitis, accompanied by abscess-like, with furunculoid granulomas. Primarily caused by animal pathogenic (zoophilic) dermatophytes. S.u. Tinea. The disease is often misdiagnosed, so that the clientele often consists of insufficiently pretreated cases.

Itchy or moderately painful, 0.5-5.0 cm large, usually well defined, cushion-like raised, purulent, highly red inflammatory plaques or nodules. The inflammatory nodules are often interspersed with follicular pustules. A confluence of pustules is rarer. Pus can be emptied under pressure. Hairs are missing in the lesion or exist only sparsely. Hairs that still exist can be easily and usually painlessly extracted (preparation of a native preparation for fungal detection).

Alopecia areata: No itching, no signs of inflammation, no scaling of the surface.

Boils: Highly painful, occurring acutely; originating from a follicle; no multiple pustules on the surface, clearly fluctuating.

Folliculitis decalvans: Eminently chronic course of the disease, usually over years; scarring alopecia. Highly red skin changes with mostly atrophic shiny center. Marginal follicular papules, later pustular transformation and crust formation. This results in irregularly shaped foci of scarring with small, irreversible hair loss. Formation of tufts of hair.

Folliculitis sclerotisans nuchae: occurs almost exclusively in black men; usually localized in the nape of the neck. Hard, dark red, hemispherical, shiny nodules of varying size, pierced by terminal or vellus hairs, which may confluent. Furthermore, bulging, sclerotic hardening of the intervening skin.

As a first step, a local shave is recommended as well as a consistent local treatment with griseofulvin cream(e.g. Gricin) or topical broad-spectrum antifungals such as amorolfin cream(Loceryl), ketoconazole cream(e.g.Nizoral), terbinafine cream(e.g. Lamisil), Ciclopirox ointment(e.g. Batrafen), Clotrimazole ointment(e.g. Canesten) or bifonazole cream(e.g. Mycospor). The externals should be applied to the inflammatory lesion as thick as the back of a knife. Then cover with a gauze compress and fix with a tubular bandage. The dressing is changed daily (if necessary 2 times/day). The ointment residues can be carefully absorbed with olive oil. Hair washing with a mild syndet (e.g. Dermowas) is possible.

Absolutely necessary. Systemic antimycotics are recommended over a period of 8-12 weeks, at best 10-14 days beyond the clinical healing stage. S.u. Tinea capitis.
