What is the best treatment for tinea cruris?
The treatment of tinea cruris consists of the administration of any of several antifungal oral or topical medications. All azoles are effective, whereas nystatin exhibits no activity against tinea. Terbinafine (Lamisil) and ciclopirox (Loprox) are active agents as well. These are applied once or twice a day, and are appropriate therapy when tinea cruris is mild, limited in extent, and shows no signs of fungal folliculitis. When abundant coarse hair or folliculitis is present, or when tinea is extensive, patients respond best to oral medication. Options include the azoles, fluconazole (Diflucan) 100–200 mg weekly for 2–4 weeks, or itraconazole (Sporonox), 100 mg/day or ketoconazole, 200 mg/day until clear. Griseofulvin 500 mg twice daily is effective as well, but nausea and headaches are often limiting side-effects. Oral terbinafine 250 mg daily until clear is effective and well tolerated. All of these medications, except for griseofulvin, also treat Candida in case of a misdiagnosis.

It is more prevalent in warm or moist climates. 51 It may be caused by any of the dermatophytes making up the genera Trichophyton, Microsporum, and Epidermophyton. 52 In children the most common cause is T. tonsurans.53 Sites of predilection include the nonhairy areas of the face, trunk, and limbs with exclusion of scalp (tinea capitis), bearded areas (t. barbae), hands (t. manuum), nails (onychomycosis), groin (t. cruris), and feet (t. pedis).

What causes fungal infections?
Superficial fungal infections may be caused by yeast or dermatophytes. Deep fungal infections of the skin are rare, and occur mainly in severely immunocompromised patients. Dermatophytes are molds that require keratin for nutrition and must live on stratum corneum, hair, or nails to survive. Human infections are caused by Epidermophyton, Microsporum and Trichophyton spp. These infections differ from candidiasis in that they are rarely, if ever, invasive. Transmission is person-to-person, animal-to-person and (rarely) soil-to-person. The organism may persist indefinitely. Most people do not develop clinical fungal infections; those who do may have impaired T-cell responses from an alteration in local defenses (e.g. due to trauma, with vascular compromise) or from primary (hereditary) or secondary (e.g. diabetes, HIV) immunosuppression.

Abstract
Erythroderma or exfoliative dermatitis is a potentially fatal condition with myriad etiologies. Identifying the cause is essential for proper treatment. Dermatophytosis is an unusual cause of erythroderma. The use of topical steroids can alter the clinical picture of dermatophytosis.
INTRODUCTION
Erythroderma is a potentially life-threatening condition which can often pose a dilemma in determining the etiology and hence treatment. Initial histopathology may not always yield typical features of the underlying disease.
CASE REPORT
A 65-year-old man presented to our outpatient department (OPD) with a history of generalized erythema and scaling. He reported that his complaints had started 2 months back as pruritic lesions over the lower back, for which he had applied an over-the-counter topical medication. There was an initial symptomatic improvement for a few days.
DISCUSSION
Erythroderma, or exfoliative dermatitis, is a disease characterized by erythema and scaling involving >90% of the body surface area. [ 1] The single most common cause of adult erythroderma is a pre-existing dermatosis, the most frequent of which are psoriasis and eczema.
CONCLUSION
Tinea incognito is an uncommon, but important cause of erythroderma, which may pose a diagnostic challenge due to steroid induced alteration of clinical picture.
