A Case of Lichen Planopilaris / 대한피부과학회지

Lichen planopilaris is believed to be a variant of lichen planus which is occasionally accompanied by classical lichen planus. A 68-year old male had asymptomatic skin colored or light violet colored papules and nodules on the occipital area followed by hair loss for 2 months. He had also violaceous pea to bean sized whitish scaly papules on the right lower extremity. Histopathological examination revealed the dilated follicles to be filled with horny material. There were also intense infiltrations of monocytes which were most prominent at the lower pole of the hair follicles on the scalp lesion. There was also hyperkeratosis, focal hypergranulosis and band-like infiltrations of lymphocytes at the dermo-epidermal junction on the lesion of the lower extremity. Direct immunofluorescence examination showed linear deposition of fibrin at the dermo-epidermal junction in the hair follicles. We had an opportunity to observe a man with lichen planopilaris who had loss of scalp hair which was accompanied by classical lichen planus on the lower extremity.

Clinical and Mycological Studies of Tinea Capitis in Chonnam Area (1986-1995) / 대한의진균학회지

BACKGROUND: The incidence, clinical characteristics and the causative fungi of tinea capitis vary according to geography and time. Although the clinical and mycological studies of tinea capitis have been widely reported in other provinces, the study in Chonnam province has not been estabilished yet. OBJECTIVE: The purpose of this study was to evaluate the prevalence, epidemiological and clinical features and the etiologic agents of tinea capitis in Chonnam area. METHODS: We performed clinical and mycological studies on 72 cases of tinea capitis which have been diagnosed by KOH examination or fungus culture or treatment trial among outpatients of Dermatologic Clinics of Chonnam University during 10 years. RESULTS AND CONCLUSION: The incidence of tinea capitis was 0.15% of outpatients and 2.6% of 2,889 superfical fungal infections. The ratio of male to female patients was 1 : 1.05. Most of patients(64 cases, 89%)were children under the age of 15, and 8 patients(11%) were the age of 15 to 80. The most common site of tinea capitis was parietal. Tinea faciale was combined in 14 cases(19.4%). In clinical features, the gray patch type was showed in 43.0%, pustular folliculitis-like in 25.0%, kerion celsi in 22.2%, seborrhic dermatitis-like lesion in 9.7% of patients with tinea capitis. Microsporum(M) canis was the most common causative fungi of tinea capitis(76.4%), with Ttichophyton(T) mentagrophytes(11.8%), T. rubrum(5.9%), T. verrucosum(2.0%), T. violaceum(2.0%), M. gypseum(2.0%) in the order of decreasing frequency.

A Case of Creeping Eruption / 대한피부과학회지

Creeping eruption is a rare cutaneous serpiginous eruption caused by fhe accidental invasion of the skin by parasites. The patient was a 26 year-old female presented with a severe pruritic erythematous serpiginous linear skin lesion on the dorsal surface of left foot for 10 days. Histopathologic finding revealed a typical burrow containing inflammatory cells and necrotic epithelial cells in the epidermis and diffuse patch infiltration of mononuclear cells and eosinophils in the dermis. Laboratory examination shows eosinophilia. The patient was treated with oral flubendazole 500mg per day for 10 days. The skin lesion disappeared without. recurrence. We described a typical case of creeping eruption never reported in Korea.
