11/32. Case report. trichophyton mentagrophytes var. nodulare causing tinea pedis.The identification of trichophyton mentagrophytes var. nodulare is described, based on a strain recently isolated from tinea pedis. Different culture media and physiological tests were used in order to compare this strain with related strains. The main characteristics of T. mentagrophytes var. nodulare were its deep yellow-orange pigmentation, which was released from the mycelium, the flat growth of its colonies and the formation of nodular bodies. Supplementation of Sabouraud glucose agar with 3% NaCl reduced the aerial mycelium and stimulated the formation of conidia. Until now an identification of T. mentagrophytes var. nodulare based on dna-patterns has not been published. trichophyton mentagrophytes var. nodulare is supposed to be an anthropophilic dermatophyte causing ordinary tinea and onychomycosis. The low number of reports indicates that it is a very rare variety.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
12/32. dermoscopy in the diagnosis of tinea nigra plantaris.Tinea nigra is a relatively uncommon dermatiaceous fungal infection, usually caused by Phaeoannellomyces werneckii, that may mimic a melanocytic lesion. We describe the value of epiluminescent dermoscopy of tinea nigra plantaris compared with other common diagnostic tools and procedures available (clinical appearance, potassium hydroxide [KOH], culture, culture mount preparation, and biopsy). A case of tinea nigra plantaris was evaluated clinically, microscopically with KOH, and dermatoscopically. Dermatoscopic findings were evaluated according to the Stolz system. dermoscopy, clinical presentation, and microscopy with KOH all confirmed the diagnosis, with dermoscopy being the fastest and simplest procedure. dermoscopy is a useful clinical adjuntive tool in differentiating tinea nigra from a melanocytic lesion.- - - - - - - - - - ranking = 1.1666666666667keywords = tinea (Clic here for more details about this article) |
13/32. Case Report. tinea pedis and onychomycosis in primary school children in turkey.A cross-sectional study was performed in two primary schools with different socioeconomic status in the suburban and central areas of Manisa, turkey, in order to determine the prevalence of tinea pedis and onychomycosis. A full dermatological examination and a questionnaire on socioeconomic conditions were performed in a group of 785 randomly selected children aged 6-14. Of 9 clinically suspected tinea pedis and 4 onychomycoses cases, KOH examination (direct microscopy) and/or mycological cultures were positive in six boys, in whom candida glabrata and C. tropicalis grew. Older age and higher number of siblings were found to be significant factors for fungal infection.- - - - - - - - - - ranking = 0.33333333333333keywords = tinea (Clic here for more details about this article) |
14/32. Case Report. Bullous tinea pedis in an elderly man.We report a case of recurrent bullous tinea pedis that had been misdiagnosed for a long time and treated with oral steroids. Initially, direct microscopy of potassium hydroxide preparations was negative and culture did not reveal any fungal organism. In a biopsy taken simultaneously from the edge of a bulla and stained with periodic acid-Schiff, septate mycelia were clearly visible. trichophyton mentagrophytes was later identified in repeated cultures. The infection resulted in two clinical variants of tinea: initially, the vesiculobullous type and later - after intake of steroids because of an unrelated disease - the dry squamous hyperkeratotic type. The change of the clinical pattern indicates the important role of the host's immune response in determining the clinical presentation of the disease.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
15/32. erythema nodosum in patients with tinea pedis and onychomycosis.To document association between erythema nodosum and concomitant fungus infection, we studied seven white women seen during a six-year period in our office practice. Five patients are presented. Unilateral erythema nodosum occurred in three patients on the same side as unilateral tinea. Tests with potassium hydroxide (KOH), cultures of nodules on Sabouraud agar and dermatophyte test medium (DTM), skin biopsy, and clinical examination ruled out nodular granulomatous perifolliculitis of Wilson. Lesions simulating erythema nodosum were produced when trichophyton antigen was injected subcutaneously in the lower legs. All nodose and fungal lesions cleared after griseofulvin therapy. Fungus infection of feet or nails should be considered a possible cause of erythema nodosum when no other cause is apparent.- - - - - - - - - - ranking = 0.83333333333333keywords = tinea (Clic here for more details about this article) |
16/32. Treatment of acquired syndactyly by gauze-fixed epidermal graft after radiosurgery.BACKGROUND: Acquired syndactyly is a rare disease that occurs mostly after disease, trauma, or other inflammatory conditions. It is usually treated by surgical incision with a flap or full-thickness skin graft, which is very invasive and requires hospitalization. OBJECTIVE: The objective was to treat acquired syndactyly with an epidermal graft by suction blister after radiosurgery, because this procedure is much less invasive and can be performed in an outpatient base. methods: A 65-year-old Korean woman had acquired syndactyly after various traditional treatments for tinea pedis. Five days after separation of syndactyly with radiosurgery, we prepared an epidermal sheet by suction blister, placed it on sterile meshed gauze, and applied it to the separated lesion. RESULTS: The patient's lesion was completely healed after 7 days. CONCLUSION: Gauze-fixed epidermal graft after radiosurgery is a very effective and simple treatment for shallow acquired syndactyly.- - - - - - - - - - ranking = 0.16666666666667keywords = tinea (Clic here for more details about this article) |
17/32. Acral lentiginous melanoma misdiagnosed as tinea pedis: a case report.The incidence of acral lentiginous melanoma (ALM) varies in different ethnic groups. Volar skin is a relatively infrequent site of malignant melanoma in Caucasian patients, although the foot is the most common site of involvement in Asian and African populations. diagnosis of ALM is usually delayed and melanomas can be diagnosed at advanced clinical stages, so the prognosis is often poor. We present a Caucasian Turkish man with ALM on the interdigital site of his foot, however, as a result of maceration of the surrounding skin, it seemed to be tinea pedis.- - - - - - - - - - ranking = 0.83333333333333keywords = tinea (Clic here for more details about this article) |
18/32. trichophyton rubrum in the external auditory meatus.We report the case of a 28-year-old immunocompetent male suffering from otitis externa. The right external auditory meatus was filled with cerumen and detritus, the tympanic membrane covered wallpaper-like with layers of fungi. Mycological analysis revealed trichophyton rubrum. With further examination tinea pedis of plantar and interdigital type and concomitant onychomycosis of the toenails due to T. rubrum could be detected. The auditory meatus was cleaned and treated topically with clotrimazole. Two weeks later the auditory meatus and the tympanic membrane were bare of fungi and the inflammation was resolved. Treatment of tinea pedis and onychomycosis with terbinafine (systemically and topically) is still lasting.- - - - - - - - - - ranking = 0.33333333333333keywords = tinea (Clic here for more details about this article) |
19/32. Bullous tinea pedis in two children.tinea pedis is a dermatophytic infection with a high prevalence in adults and also occasionally observed in children. We report here two cases of bullous tinea pedis, one due to trichophyton rubrum in a 6-year-old child and the second due to T. interdigitale in a 10-year-old child. We suggest that, despite the low prevalence of this infection in childhood, a potassium hydroxide test and a culture for fungi should always be performed when a child is examined for an inflammatory eruption of the feet.- - - - - - - - - - ranking = 0.83333333333333keywords = tinea (Clic here for more details about this article) |
20/32. trichophyton eboreum sp. nov. isolated from human skin.An unusual dermatophyte was isolated from the plantar scales of a human immunodeficiency virus-positive man with tinea pedis. Morphology, physiology, and molecular data provided evidence to support the new species trichophyton eboreum. This dermatophyte is characterized by rapid growth on common mycological media, a flat powdery off-white colony, formation of clavate microconidia, smooth- and thin-walled cylindrical or club-shaped macroconidia with two to nine cells, the presence of hook-shaped hyphae, the production of cleistothecium-like structures and spiral hyphae in older cultures, positive hair perforation, the absence of pigmentation on potato glucose agar, the absence of a requirement for vitamins, a weak positive urease reaction, no growth at 37 degrees C, resistance to 5% NaCl, resistance to fluconazole, good growth on human epidermal keratin, and the production of various enzymes on different media by the API-ZYM test. More than 5% divergence from any known species of dermatophyte was revealed by sequence analysis of the internal transcribed spacer of the rRNA gene.- - - - - - - - - - ranking = 0.16666666666667keywords = tinea (Clic here for more details about this article) |
