N/A Background : Pityriasis rubra pilaris (PRP)is a rare papulosquamous disorder of unknown etiology. Although the clinical and histapathologic features of PRP are relatively well known in western patients. there are few available studies in Korea. Objective : The purpose of this study was to evaluate the clinical and histopathologic features of pityriasis rubra pilaris(PRP) in Korea Methods : The clinical them, photographies and skin biopsy slides of patients clinically diagnosed s PRP at the initial visit were reviewed. Finally 30 patients were diagnosed as PRP. They were classified into 5 groups according to the Griffiths classfication. And then the evaluation of age at uses, sex distribution, clinical feature of the skin lesion, associated symptoms. clinical course and histapathologic features were conducted. Results : 1) The male to female ratio was 1:1.14. The age of onset was varied from 1 to 65 years with two peaks in first and fifth decades. The average age, of onset in adult type and juvenile type were 40.1 and 5.1 years respectively 2) According to the Griffiths classification, 14(47%) of the patients had type Ⅰ, 4(13%) had type Ⅲ, 7(23%) had type Ⅳ. and 3(10%) had type Ⅴ. However, 2(7%)patients could not be classified under any of these five types due to atypical clinical feature or insufficient follow-up periods 3) The common clinical features during the disease course were follicular hyperkeratosis(83%), knee and/or elbow involvement(83%), palm and/or sole hyperkeratosis(80%). Erythroderma was present in 5 patients(17%) during the disease course 4) There were no specific symptoms in most cases but 9 patients had on .offered from mild itching 5) 3 patients had a positive family history, and were thought to have inherited autosomal dominant trait 6) The frequent histopathologic findings were alternating parakeratosis and orthokeratosis (100%), superficial perivascular infiltration(100%), broad rete ridge(97%), acanthosis(93%), hypergranulosis(87%), follicular plugging(73%). Conclusion : We investigated the clinical and histopathological features of PRP in Korea. In our study, the clinical and histopathological features of PRP were not different from those observed in western patients.

Epiluminescence microscopy 를 보조적으로 이용하여 진단한 색소성 기저세포암 2 예

Basal cell carcinomas(BCCs) are the most common skin cancers in Korea and a proportion of BCCs contain pigment. Pigmented basal cell carcinomas(PBCCs) are included in the differential diagnosis of invasive melanoma and other benign pigmented skin lesions(PSLs) because of their growth patterns and asymmetry of pigmentation. Epiluminescence microscopy(ELM) describes the non-invasive in vivo examination of skin lesions with a microscope using incident light delivered from an acute angle and oil immersion. Many studies have shown that epiluminescence microscopy can improve the diagnostic accuracy of PSLs. Menzies et al analyzed the morphologic features of a large set of 142 pigmented BCCs and produced a simple ELM method for diagnosis that would allow differentiation from melanomas and benign pigmented lesions. We observed morphologic features of two PSLs with a handheld 10 epiluminescence microscopy (Episcope, Welch Allyn Inc, Skaneateles Falls, NY). After the ELM examination, two PSLs were excised and processed for histopathology. The ELM findings and histopathologic diagnosis were compared for each lesion. ELM permits the recognition of two PBCCs and the fact that it is a non-invasive in vivo method makes it even more attractive as a diagnostic tool in clinical practice.

Tufted hair folliculitis is an inflammatory disorder of the scalp characterized by a peculiar tufting of hair within areas of scarring alopecia. Histopathological studies reveal perifollicular inflammation around the upper portions of the follicles sparing the hair root level. Within areas of inflammation, several follicles converge toward a common follicular duct with a widely dilated opening. The cause of tufted hair folliculitis is unknown, and the therapeutic approach is problematic. We present herein a patient with a 28-year history of recurrent and progressive tufted hair folliculitis. A 33-year-old man was referred to our department for the treatment of chronic and relapsing inflammatory lesions of the scalp. The clinical examination revealed a circumscribed area of 15cm length and 10cm width on the occipital area of the scalp which was characterized by hair tufting and exudates. Histopathologic findings were typical for tufted hair folliculitis. We believe that hair tufting is a secondary phenomenon which may occur in several inflammatory diseases of the scalp.

양측성 Ito 모반이 동반된 양측성 Ota 모반 1 예
김수남,계영철,서수홍,정증태 대한피부과학회 2001 大韓皮膚科學會誌 Vol.39 No.1
Benign pigmented lesions derived from dermal melanocytes include the Mongolian spot, the nevi of Ota and Ito, and the blue nevus. The nevus of Ito differs from the nevus of Ota by its location in the supraclavicular, scapular and deltoid regions. It occurs rarely in association with bilateral nevus of Ota. We present a 70 year old male, showing extensive involvement of dermal melanocytic nevi, so called bilateral nevus of Ota associated with bilateral nevus of Ito.
