Dermatology · Fungal infections: Majocchi granuloma
Sample itemA woman applied a potent steroid-antifungal cream to a groin rash. It spread with follicular pustules and papules and KOH of hair shows fungal elements. Why do topical antifungals alone often fail here?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Fungus is deep within hair follicles, so oral therapy is needed
Majocchi granuloma is a deep folliculitis by dermatophytes, usually Trichophyton rubrum, often modified by topical steroids (tinea incognito). Because the fungus lies deep in the follicle, systemic antifungals are required.
Option by option
A. Fungus is deep within hair follicles, so oral therapy is needed (correct)
Correct. Follicular depth needs systemic antifungals.
B. Steroids have no effect on the infection
Topical steroids modify the appearance and promote spread.
C. The causative organism is a virus
Viruses do not cause this.
D. The infection is a bacterial folliculitis
The cause is fungal, not bacterial.
