1/41. tinea pedis in children.

    Many children have dermatoses involving the feet. Such problems are often misdiagnosed as tinea pedis, which is relatively uncommon in this age group. On the other hand, tinea pedis should not be ignored as a diagnostic possibility just because of its infrequent occurrence. Six cases are reported to demonstrate that this diagnosis will be missed if appropriate laboratory studies are not done as a part of the evaluation of these dermatoses. ( info)

2/41. Two cases of tinea pedis caused by Scytalidium hyalinum.

    Two cases of tinea pedis due to Scytalidium hyalinum, the first to be described in italy, are reported. The patients were a 41-year-old woman and a 35-year-old man who had spent periods in the Caribbean. The clinical manifestations were indistinguishable from those caused by dermatophytes. In the women they were striking with 'moccasin foot' type lesions, whereas in the man they were less evident, with minor plantar desquamation and interdigital maceration. diagnosis was based on direct mycological microscopic examination and culture. Clinical and mycological remission were obtained with systemic itraconazole therapy. These cases are reported because infections caused by Scytalidium hyalinum are rare in europe and their clinical and mycological diagnosis, as well as therapy, may be problematic. ( info)

3/41. Acute infection with trichophyton rubrum associated with flares of atopic dermatitis.

    trichophyton rubrum has been implicated as a potential trigger in flares of atopic dermatitis. We describe a patient with atopic dermatitis who presented with a history of multiple flares and concurrent acute tinea pedis and onychomycosis. Symptoms of atopic dermatitis and culture-positive acute infection with T. rubrum resolved during each flare using systemic antifungals. Flares of atopic dermatitis may be triggered by acute T. rubrum infections. Antifungal therapy should be considered in these patients. ( info)

4/41. tinea pedis in children presenting as unilateral inflammatory lesions of the sole.

    tinea pedis is uncommon in prepubescent children and therefore the diagnosis may be difficult to make. We report tinea pedis in five children presenting as unilateral inflammatory lesions of the sole which was not readily diagnosed. The pathogen in all of our cases was trichophyton rubrum. ( info)

5/41. Treatment of tinea nigra with terbinafine.

    We present the first reported cases of tinea nigra treated with terbinafine. Two cases responded to treatment with topical terbinafine; one case failed to respond to treatment with systemic terbinafine. ( info)

6/41. Bilateral tinea nigra plantaris and tinea nigra plantaris mimicking melanoma.

    Tinea nigra, a superficial fungal infection caused by Phaeoannellomyces werneckii, presents as a hyperpigmented, nonscaling macule of variable size and shape. Typically lacking induration, erythema, or pruritus, these "ink spot" lesions may resemble junctional nevi or malignant melanoma. Rapid, noninvasive diagnosis can be provided by potassium hydroxide examination, demonstrating numerous large, dematiaceous hyphae. ( info)

7/41. Pustular tinea pedis.

    Pustules are uncommon in tinea pedis and may suggest a bacterial infection. We describe a patient with large pustules on his feet that contained hyphae on Gram's stain of the pus and on a potassium hydroxide preparation of the pustule roof. Cultures were negative for bacteria, but grew trichophyton rubrum. ( info)

8/41. Allergic contact dermatitis from ciclopirox olamine.

    A 50-year-old man with interdigital tinea pedis developed an allergic dermatitis spreading from the toes to the lower shins. patch tests were strongly positive to ciclopirox olamine 1% pet. Sensitization to this topical antifungal agent has rarely been reported in the literature. ( info)

9/41. asthma, rhinitis and dermatitis triggered by fungal infection: therapeutic effects of terbinafine.

    We report 2 atopic patients suffering from tinea unguium caused by trichophyton rubrum. In addition, both patients had symptoms of allergies: one had perennial rhinoconjunctivitis and bronchial asthma, the other had chronic dermatitis of the face and neck. In both cases, their allergy symptoms improved dramatically during oral therapy with the antifungal agent terbinafine (250 mg/day) and relapsed after its discontinuation. ( info)

10/41. A better potassium hydroxide preparation? In vivo diagnosis of tinea with confocal microscopy.

    BACKGROUND: Traditional diagnostic testing for dermatophyte infection currently requires skin scraping for light microscopy and/or fungal culture or skin biopsy. Immunofluorescent microscopy can also be used with calcofluor stain. All of these tests can be time-consuming to perform, require a waiting period for results, and are invasive. We investigated the use of a real-time, noninvasive, confocal microscope in visualizing dermatophyte hyphae in vivo. OBSERVATIONS: Confocal microscopic imaging of active tinea can clearly identify dermatophyte hyphae within the upper epidermis after potassium hydroxide application. The hyphae appear as bright linear branching objects not found in uninvolved skin. CONCLUSIONS: It is possible to immediately and painlessly image dermatophyte hyphae in active lesions of tinea by means of a confocal microscope. With further improvement, imaging devices may be available to physicians to instantly and noninvasively evaluate a variety of skin disorders in microscopic detail. ( info)
