Kerion celsi is a severe inflammatory type of tinea capitis that presents as a boggy mass studded with broken hairs, oozing purulent material from follicular orifices. This infection is caused most commonly by zoophilic or geophilic pathogens. Trichophyton(T.) rubrum is an anthropophilic dermatophyte that is found all over the world. It has become one of the most important causative agents in tinea unguium and tinea pedis. But, kerion celsi caused by T. rubrum is rare. Kerion celsi is uncommon in adult. We report a case of kerion celsi caused by T. rubrum in a 72-year-old woman. She presented with localized tender erythematous plaques with pustules with oozing purulent material on the frontal scalp. A fungal culture from tissue of the lesions was grown on Sabouraud's dextrose agar and showed typical whitish cottony colonies of T. rubrum. The nucleotide sequence of internal transcribed spacer region for clinical isolate was identical to that of T. rubrum strain UZ1588_14 (GenBank accession number KP326579.1). She was treated with 200 mg of oral itraconazole daily for 3 months. The skin lesions improved 1 month after treatment, and recurrence has not been observed.

BACKGROUND: Pediatric onychomycosis has been previously investigated; however, the specific causative agents of onychomycosis in Korean children have not been reported. OBJECTIVE: This study aimed to determine the most common causative agents of onychomycosis in Korean children. METHODS: We reviewed the medical records of 149 pediatric patients (<18 years of age) referred for fungal cultures because of a clinical suspicion of onychomycosis between 2005 and 2014 at our clinic. Patient specimens were cultured on Sabouraud's dextrose agar with and without cycloheximide. RESULTS: Onychomycosis was clinically suspected in 149 children. Of the 44 patients with onychomycosis, confirmed by culture, 72.7% had toenail onychomycosis, 22.7% had fingernail onychomycosis, and 4.5% had toenail and fingernail onychomycosis. The male-to-female patient ratio was 1.93:1. Fourteen (31.8%) children had concomitant tinea pedis, and 12 (27.2%) had family members with tinea pedis or onychomycosis. Distal and lateral subungual onychomycosis were the most common (68%) clinical types. Trichophyton rubrum was the most frequently isolated pathogen (66.7%), followed by Candida albicans (14.8%), Microsporum canis (11.1%), Candida parapsilosis (3.7%), and Candida tropicalis (3.7%). Candida albicans was the most commonly isolated pathogen (50.0%) in fingernail onychomycosis. CONCLUSION: Pediatric onychomycosis is more common than most people think. Thus, we suggest the need for a careful mycological examination of children with suspected onychomycosis.

Trichophyton(T.) rubrum is an anthropophilic dermatophyte that is found all over the world. It has become one of the most important causative agents in tinea pedis and onychomycosis. But tinea capitis caused by T. rubrum is rare. Tinea capitis is uncommon in an adult. We report a case of tinea capitis caused by T. rubrum in an 81-year-old woman. She presented with localized asymptomatic well-demarcated thick scaly erythematous patches on the fronto-vertex scalp for 6 months. She was diagnosed as seborrheic dermatitis in local clinic and was treated with topical steroid. However, the lesion was not improved and spreading. Culture from scalp lesion of patient was grown on Sabouraud's dextrose agar and showed typical whitish cottony colonies of T. rubrum. She was treated with 200 mg of oral itraconazole daily for 8 weeks. The skin lesions improved 8 weeks after treatment, and recurrence has not been observed.

BACKGROUND: A variety of dermatological disorders develop in hospitalized patients and the need for dermatological consultations is on the rise. OBJECTIVE: We analyzed 2 years of dermatological consultation data from a tertiary medical center in Korea and compared dermatological problems among individual departments. METHODS: We reviewed 3,102 dermatological inpatient consultations by performing a retrospective chart review. RESULTS: Contact dermatitis (11.4%), drug eruption (9.6%), tinea pedis (5.5%), xerotic eczema (5.3%), and seborrheic dermatitis (5.2%) were the 5 dermatological disorders that were most commonly referred to dermatologists. Patients in the allergy and pulmonology departments had higher rates of drug eruptions. Endocrinology-admitted patients, especially diabetic patients, frequently complained of foot dermatitis. The cardiology, gastroenterology, and hemato-oncology departments referred many patients with purpuric dermatosis to dermatologists. Patients from the surgical departments consulted more frequently consulted contact dermatitis and drug eruptions. The neurology and rehabilitation medicine departments referred more seborrheic dermatitis patients than other departments. Pediatric patients commonly consulted for atopic dermatitis, viral exanthemata, and seborrheic dermatitis. Regardless of department, patients who suffered from severe illness and underwent major surgery developed herpes zoster and cutaneous fungal infections more frequently than other patients. Personal hygiene was closely related to the development of follicular disorders. CONCLUSION: Dermatologists should be familiar with the diverse dermatological complaints of patients admitted to various departments and be actively involved in the diagnosis, treatment, and education of doctors and patients to improve the quality of inpatient care.

Trichophyton rubrum is a common cause of superficial dermatophytosis in humans, such as tinea pedis, tinea unguium, tinea corporis and tinea cruris. T. rubrum usually attaches to keratin of the epidermis and uses it as a source of nutrients. Therefore, isolation of T. rubrum from non-keratinous skin, such as ulcer, is very rare. We describe 4 patients with T. rubrum-infected diabetic foot ulcer.

BACKGROUND: Trichophyton(T.) rubrum is most common fungal pathogen that causes tinea pedis and onychomycosis. It recurrently infects human and usually persists for very long time, provoking public health concern. Due to the limitation in current treatment options, alternative therapies are desirable. We investigated the inhibitory effect of UVC, terbinafine hydrochloride 1% and paeonia natural extracts on T. rubrum in vitro. OBJECTIVE AND METHOD: Total 25 T. rubrum strains were cultured for 10 days on Mycosel agar plate; 5 strains of T. rubrum and 5 copies for each strain. They were divided into 5 groups: control, UVC irradiation, terbinafine spray, paeonia natural extracts spray, UVC and paeonia natural extracts sprays. The cultured media were irradiated for 1 hour daily for 3 weeks in the germicidal lamp emitting 253.7 nm (UVC), power of 2.875 mW/cm2 at 10 cm distance. Terbinafine and paeonia extracts was sprayed twice on the surface to fully cover the colony area. The median diameter of each colony were measured every other day for 3 weeks. The change of colony diameter and the growth rate were analyzed. RESULTS: The UVC had virtually no effect on restraining the growth of T. rubrum, similar with the growth of the control group. However, both the terbinafine spray and paeonia extracts slowed down the growth rate remarkably and showed a similar effect. CONCLUSION: We could only figure out the fungistatic effect, and not the fungicidal effect of paeonia extract and terbinafine hydrochloride in vitro. UVC irradiation setting in this study was totally ineffective. More studies are needed on more variable wavelength and the fluence of UVC irradiation. In addition, further verification on the mechanism and the effect of anti-fungal activity by paeonia extracts are needed.

BACKGROUND: Cellulitis is an acute infection of the dermal and subcutaneous layers of the skin, which is commonly treated by a dermatologist but there are few reports about clinical data on cellulitis in Korean literature. OBJECTIVE: This study evaluated the clinical characteristics of inpatients diagnosed as cellulitis in the recent 5 years. METHODS: We reviewed the medical records of 77 patients who were diagnosed as cellulitis and hospitalized at the Kangbuk Samsung Hospital from March 2008 to February 2013. RESULTS: The study included data from 77 patients with cellulitis (mean age, 51.7 years; 44 men, 33 women). There was a positive correlation between age and hospitalized days (p<0.05). Cellulitis most frequently occurred in the foot (32.1%). The most common cutaneous symptoms were erythema, tenderness, and swelling (100%), and the most common systemic symptom was fever (23.4%). Tinea pedis was the most common cause of cellulitis (31.2%). Elevation of C-reactive protein (CRP) was observed in 30 patients (40%) and there were positive correlations not only between CRP and hospitalized days (p<0.05) but also between white blood cell (WBC) count and hospitalized days (p<0.05). First-generation cephalosporin was chosen as the primary antibiotic in 33 patients (40.3%) and the mean duration of antibiotic treatment was 12.4 days. There was no significant difference of hospitalized days between first-generation cephalosporin and other antibiotics (p>0.05). Systemic steroid was administered in 21 patients (27.3%), and was not significantly related to hospitalized days (p>0.05). CONCLUSION: The clinical course of cellulitis was inversely correlated to the elevation of patient's age, WBC count, and CRP.

BACKGROUND: The prevalence and clinical characteristics of dermatomycosis are not static but change under the influence of various forces such as geographic factor, social environment and development in prophylaxis and treatment. OBJECTIVE: To investigate the present status of dermatomycosis and changes on the prevalence, sex, age distribution and causative organisms. METHODS: We performed clinical and mycological studies on 7,785 cases of dermatomycosis among outpatients of Dermatologic clinic of Chonnam University Hospital for 10 years, from January 2001 to December 2010. RESULTS: The incidence of dermatomycosis was 12.5% of outpatients and show the highest incidence over 7th decades (24.2%). The incidence of tinea pedis (24.1%) was the highest, followed by onychomycosis (18.1%). Coexisting fungal infections were found 693 (9.2%) and the cases of tinea pedis with onychomycosis were the most common. The positive rate of KOH examination was 49.7% and the positive rate of culture on Sabouraud's dextrose agar media was 36.5%. Trichophyton rubrum was the most common causative organism of dermatomycosis (51.1%), followed by Candida species (33.2%). CONCLUSIONS: Consideration of the changes between current and past epidemiologic, clinical and mycological features in the cutaneous fungal infections are important to investigational efforts, diagnosis, and treatment.
