Disseminate and recurrent infundibulo-folliculitis is a rare,but distinctive dermatosis characterized by pruritic papular follicular eruption over the trunk and proximal extremities with histologic findings of lymphocytic infiltrations and spongiosis confined to the infundibulum. Little is known about the cause. Resistance to treatment is one of the characteristics of this disease. We herein report a case with typical clinical and histological findings in a 22 year old male.

The incidence of skin diseases in the hospital practice cannot give a true picture of their prevalence in the population served. Nevertheless the hospital incidence figures usually offer the only available means of assessing prevalence, and therefore provide us with a potentially valuable source of information on the ecology of many skin disorders.

Trichostasis spinulosa was first described by Nobl in 1913 to denote a condition characterized by protruding groups of hairs embedded in horny mass on the nose, forehead, shoulder, and back. We report a case a 27-year old male patient with trichostasis spinulosa who showed multiple black colored papules on his back and upper arms. Histologic examination showed hair follicles surrounded by hyperkeratotic band which had multip]e hairs. By scanning electron micnoscopy, also, we could find several hairs of different size in the hyperkeratotic hair shealh.

We describe a case of cutaneous chylous reflux, which is thought to be a kind of primary lymphedema, in a 19-year-old male who had suffered from multiple vesiculobullae and intermittent swelling on scrotum for about 6 years. Histopathologic findings showed multiple dilated lymphatic vascular channels in papillary dermis.

Verrucous czrcinoma is a well accepted clinicopathologic entity that is a lowgrade variant of squamous cell carcinoma. This tumor develops typically in moist areas which are frequent site of chronic inflammation. We herein report a case of verrucous carcinoma developed in a burn scar on. the posterolateral aspect of left popliteal fossa.
Behcet 증후군의 분류아형에 따른 체액면역에 관한 고찰

Various immunologic studies were performed for the investigation of humoral immunity in 30 patients with Behcet's syndrome who had been registered in Behcet Special Clinic of Severance Hospital: direct immunofluorescent staining, quantitation of serurn Ig, complement by immunoelectrophoresis and B-cell by EAC-rosette method. The results can be summerized as follows: 1. Direct immunofluorescent staining occurs in biopsies from patients with Behcets syndrome: 11 of the 30 patients(36. 7%). Among them, vascular fluorescene with C3 was noted in 10 of 11 patients (90. 9%), in addition of IgG, IgA, IgM, and fibrinogen on dermoepidermal junction or vessel. 2. The results of direct immunofluorescence staining showed different tendency according to biopsy sites and clinical types: 5 of 10(50%,) in the specimens from oral mucosa, 5 of 13(38.5%) from leg, 1 of 3(33.3%,) from genitalia, and 0 of 7(0%) from other sites: higher in complete and incomplete types than in suspected and possible types. 3. Immunofluorescent staining rates were statistically not significant according to sex, age and Lehner's classification. 4. Serum IgG, IgA, IgM, C3, C4 and B-cell were statistically not significant between DIF positive and negative groups. Therefore it is considered that vascular deposits of immune complexes and activation of complements by immune omplexes may be a role of pathogenetic mechanisms of Behcet's syndrorne.
Behcet 증후군의 세포매개 면역상태에 관한 연구 - DNCB 감작율을 중심으로 -

Various immunologic investigations of 159 patients with Behqets syndrome undertaken included; the DNCB sensitization test, total T-cells and T-cell subsets and the lymphocyte transformation test using PHA. The percentage of positive esponsiveness to DNCB decreased in the order of possible (65%), suspected (60%), incomplete (37%) and complete type (37%), The number of patients with impaired LTT was larger in the group of patients with DNCB( + ) responsiveness (seventeen of 32) than in DNCB(+) group (six of 25), There was significant impairment of cell mediated immunity in Behcets syndrome compared to normal subjects, when analyzed by the impaired LTT and decreased proportions of helper T-cells.

Background : Pyoderma gangrenosum is a rare disease in which a painful nodule or pustule breaks down to form a progressive enlarging ulcer. Until now, only 8 cases of pyoderma gangrenosum have been reported in Korea. Therefore, we thought it necessary to perform a clinical analysis of pyoderma gangrenosum in Korea with a review of literature. Objeetive: Our purpose was to find the clinical features of pyoderma gangrenosum in Korea. Metbods: Fourteen cases with pyoderma gangrenosum were investigated by reviewing medical records. Results There were 6 males and 8 females. The onset age was between 4 years and 65 years, and most(9 cases) had developed the condition between the ages of 20 and 60. Thirteen cases involved the extremities and 3 cases had whale body involvement, Seven cases(50%) had multiple lesions. All cases had pain at the lesional sites. Two cases were classified as the bullous type and the others were ulcerative in nature. The histological fmdings were non-specific. Dense inflarnmatory infiltrates composed of lymphocytes and predominant neutrophils were found in the epidermis and dermis associated with ulceration. Two cases were treated only with systemic steroids, and 2 cases with dapsone and steroids, 2 cases with colchicine and steroids, and 1 case with steroids, dapsone and colchicine. One case was treated with colchicine and anti-Tbc drug, 1 case with dapsone, 3 cases with antibotics, 1 case with the anti-Tbc drug and 1 case with anti-cancer drugs. Systemic disease was present in 5D% of the cases. The associated diseases were Behcets disease(3 cases), tuberculosis(2 cases), systemic lupus erythematosus(1 case), pancytopenia(1 case), iron deficiency anemia(1 case), acute leukemia(1 case), and colon adenoma(1 case). Recurrence developed in 2 cases and positive pathergy reactions were observed in 3 cases. Conclusion . Pyoderma gangrenosum was eccompanied with systemic disease in 50% of the cases and the most common therapeutic drugs were steroids. It is therefore impartant to detect the presence of any underlying disease and to treat this alongside pyoderma gangrenosum. (Korean J Dermatol 1998;36(5) 780-786)

A 17-year-old male had a coin sized, follicular plaque on the glabella for 3 months. Histopathologic examination revealed reticular degeneration in the pilosebaceous follicles and amorphous homogenous materials between the degenerated cells. Alcian blue and toluidine blue stained the material as blue and metachromatically purple, respectively. The material was subsequently confirmed as acid mucopolysaccharide. Two months after the initial visit, the lesion showed a tendancy to heal spontaneously. According to the data obtained, the case was considered as an acute benign form of follicular mucinosis.
