Tinea Barbae Caused by Trichophyton mentagrophytes / 대한의진균학회지

Tinea barbae is a dermatophyte infection of the bearded areas of the face and neck. The incidence of tinea barbae has decreased as improved sanitation. We report a case of tinea barbae in a 49-year-old-man, who presented with relatively well-defined erythematous patch with pustules on the upper lip. A fungal culture from tissue of the lesions was grown on Sabouraud's dextrose agar and showed typical Trichophyton mentagrophytes. The nucleotide sequence of internal transcribed spacer for clinical isolate was identical to that of Arthroderma vanbreuseghemii IHEM 4411. The patient was treated with oral itraconazole for 3 months. The skin lesions improved 3 months after treatment, and recurrence has not been observed.

Tinea barbae is a dermatophyte infection of the bearded areas of the face and neck. The incidence of tinea barbae has decreased as improved sanitation. We report a case of tinea barbae in a 58-year-old-man, who presented with relatively well-defined erythematous pustular plaque on the upper lip. A fungal culture from tissue of the lesions was grown on Sabouraud dextrose agar and showed typical Trichophyton verrucosum. The nucleotide sequence of internal transcribed spacer for clinical isolate was identical to that of Trichophyton verrucosum strain ATCC 10695. The patient was treated with oral itraconazole for 3 months. The skin lesions improved 3 months after treatment, and recurrence has not been observed.

A Case of Tinea Barbae Caused by Trichophyton mentagrophytes / 대한피부과학회지

We report a case of tinea barbae in a 51-year-old man, who presented with erythematous pustules on the upper lip, and a relatively well-defined pustular patch on his left cheek. Histopathologically, fungal hyphae were found in the hair shaft upon PAS staining. A fungal culture from scales and tissue of the lesions was grown on Sabouraud's dextrose agar and showed typical Trichophyton mentagrophytes. The patient was treated with 250 mg of terbinafine, 10 mg of prednisolone and 300 mg of roxithromycin daily for the first week, then 250 mg of terbinafine combined with topical lanoconazole for 4 weeks. The skin lesions improved 5 weeks after treatment, and recurrence has not been observed.

A Clinical, Mycological and Epidemiological Study on Tinea Barbae During the Last 24-Year-Period (1981~2004) / 대한의진균학회지

BACKGROUND: Tinea barbae(TB) is a rare dermatophytosis localized on the bearded areas of the face and neck. OBJECTIVE: The purpose of this study was to elucidate the epidemiological, clinical and mycological characteristics of TB. METHODS: During the 24-year-period from 1983 to 2004, 74 patients with TB were evaluated in regard to annual incidence, the distribution of the subjects according to age, season, involved site, occupation, a place of residence and concurrent fungal infection. Patients with TB were further assessed concerning causative agents by fungal culture and their association with clinical type and a place of residence. RESULTS: In epidemiologic aspect, annual incidence was increased until 1989, thereafter gradually decreased. TB showed peak incidence in April in monthly distribution. TB occurred predominantly in middle-aged adults, especially in fifties in age distribution and countryfolk in residential distribution. In clinical aspect, superficial type was the most common in clinical types, followed by follicular and kerion type. Upper lip was affected mostly. In mycologic aspect, fungal culture showed positive results in 57 patients. Trichophyton(T.) rubrum was the most common causative agents followed by T. mentagrophytes and T. verrucosum. Thirty six patients had concurrent fungal infection and tinea pedis was the most common. CONCLUSION: The result suggests that although the incidence of TB is decreasing, it is important not only to isolate cattle with dermatophytoses from people but also to treat concurrent dermatophytoses in order to decrease the incidence

Dermatophytosis among Filipinos: its incidence and flora in the outpatient dermatological clinic of the Philippine General Hospital

1. Mycologic laboratory studies consisting of KOH preparations for direct microscopic examination and cultural procedures for the isolation and identification of the causative pathogenic fungi were performed on 401 cases of suspected dermatophytosis in the Outpatient Skin Clinic of the Philippine General Hospital during the period August, 1948 to May, 19502. Ninety-one cases suspected of tinea pedis were studied. Twenty or 22% showed a positive KOH preparation for hyphal filaments. Eleven positive cultures were obtained, 10 of Trichophyton mentagrophytes and 1 of Trichophyton rubrum. This low figure of demonstration of the fungus is explained mainly by technical errors in the performance of the laboratory examination and the probable non-mycotic nature of a certain percentage of the cases3. Ninety-seven patients with involvement of the hands were seen and only one gave a positive KOH mount. Not a single culture showed growth of a dermatophyte4. Eighty-one cases with lesions on both feet and hands were examined. There were 15 cases with positive KOH of the feet and negative KOH of the hands. One case gave positive findings from both feet and hands. Only three positive cultures were obtained from the feet which proved to be Trichophyton mentagrophytes. None was isolated from the hand lesions5. There were 62 patients suspected of tinea corporis. Out of this total, 40 gave positive KOH mounts. Nineteen cultures were isolated, 13 of Trichophyton rubrum, 4 of Trichophyton mentagrophytes and one each of Trichophyton violaceum and Microsporum gypseum6. Fifty-six cases were diagnosed clinically as tinea cruris. Of these, 47 had a positive KOH mount. Twenty-two cultures were obtained with 19 of Trichophyton rubrum, 2 of Trichophyton mentagrophytes and one of Trichophyton violaceum. This preponderance of Trichophyton rubrum as the causative agent of tinea cruris in the series studied is in contrast to that recorded by most dermatologic textbooks which is Epidermophyton flocosum. The greater tendency of this form of tinea cruris caused by Trichophyton rubrum to spread to adjacent areas and to involve other sites was also observed7. The paucity of cases of tinea capitis, tinea unguium and tinea barbae in the clinical material studied is noted8. The results as obtained are compared with statistics reported by authors from other lands. (Summary)

Tinea Barbae due to Trichophyton verrucosum: Report of 3 Cases / 대한의진균학회지

Although there has been recently noted a nation-wide spread of Trichophyton verrucosum infection in cattle associated with promoted stock raising and dairy farming, there were no case reports in Korean dermatologic literature describing the characteristic clinical features of tinea barbae caused by that particular fungus. We report 3 cases of tinea barbae due to T. verrucosum that developed in male stock farmers breeding cattle. One Patient acted 37, experienced acutely inflamed bo99y tumors on the chin and sub-mandible. The others aged 43 and 46 experienced inflammatory lesions with multiple follicular pustules, crusts and loss of hairs on their upper lips. They were successfully treated with oral griseofulvin and local antifungal ointment combined with short-term oral antibiotics or corticosteroid for about one month.
