Proliferating trichilemmal cyst is a fascinating follicular neoplasm. Prior to its recognition, the tumor was misinterpreted as squamous cell carcinoma both clinically and histologically. The incidence of the lesion is rare and we can not find this case in the Korean literature. Authors have found a large, lobulated, hemorrhagic progressively growing tumor on the scalp of a 66 year-old woman. By its appearance it was hard to think the lesion was a benign tumor. Histological examination confirmed the diagnosis of proliferating trichilemmal cyst. Local excision and skin graft brought about complete healing of the lesion.

Papulonecrotic tuberculid (PNT) and Pityriasis lichenoides et varioliformis acuta (PLEVA) have been in controversy in their pathogeneses and entity itselves. Authors reviewed litera,tures of the two dermatoses with observation of nine casea of PNT from 1979 to 1981 and evaluated whether PNT could be also classified as PLEVA. The results were a,s follows: 1. By the review of literatures PNT and PLEVA showed great similarities in their clinical aspects including shape of cutaneous lesions, course, favorite age and subjecive symptoms. Histopathological overlappings were also found. 2. Of the nine cases of PNT authors observed, seven cases were histopathologically PLEVA and four cases could be thought PLEVA also clinically. But way six cases were treated by anti-tuberculous drugs. 3. The incidence of other tuberculous signs and results of tuberculin skin tests were all significant in the nine cases above. With the above observations it seems that PNT is one of the causes of PLEVA and thus could be a kind of PLEVA.

Venous island flap has many advantages over other flaps, such as random pattern flap, island flap or free flap. It can cover the defect with wide arc of rotation and does not require vessel anastomosis and arterial pedicle, hence more sites are available for donor. The procedure is a time saving and simple procedure and can be performed even by two operating members. But it is not frequently used because of the poor survival of the flap. In this study, we attempted to allow whether pharmacological or delay procedure can enhance the survival of the venous island flap and the mechanism of the delay flap survival. We devised a model of venous island flap whose pedicle was a branch of central vein on the auricle of Newzeland white rabbit. SOD, allopurinol and SOD and allopurinol were given as pharmacological treatment and delay procedure was carried out to enhance the survival of the flap. For the study of survival mechanism of the delay flap, SOD levels of the delay and non-delay flap were observed by SOD 525 method. The results were as follows: 1. Allopurinol, SOD and, SOD and allopurinol improved the survival of the flap significantly. 2. Delay procedure improved the survival of the flap significantly. 3. The level of SOD in delay flap was higher than that of non-delay flap regardless of the site within the flap or time passage. In conclusion, it is inferred that the administration of allopurinol and SOD and surgical delay can enhance the survival of the venous island flap. In delay venous island flap, increased level of SOD within the flap seem to contribute to the increased survival of the flap.

4.A Case of Lichen Nitidus.
Korean Journal of Dermatology 1980;18(5):479-483
Lichen nitidus is a comparatively rare, asymptomatic, chronic disease displaying small, sharpIy defined, fresh colored papules usually localized on the penis, arms and the abdomen. Waisman found immunoglobulin at the dermo-epidermaI junction in lichen planus, but not in lichen nitidus. This settled the argument whether lichen nitidus is a variant of lichen planus. A 11 year old healthy girI was brought to the clinic because of many flesh colored discrete papules on the cubital fossae and the anterior chest. The papules are skin colored. pinhead sized, round, and flat-topped The lesions appeared first at the age of 8 on the antecubital folds and in the following years, increased in number and extended slowly to the upper arms and the anteior chest.

5.Histology of Secondary Syphilid.
Korean Journal of Dermatology 1980;18(5):417-424
Fundamental pathologic cianges of secondary syphilid are said to be swelling and proliferation of endothelials and a predominantly parivascular infiltrates composed chiefly of lymphoid cells and plasma cells. But recentIy this theory has heen challenged. We present bistologic observation made on 10 patients who agreed to go through a biopsy, during 2 years period. from 1975 to l977. Male to female ratio was 9: 1 The age of patient ranged from 20 to 33, with a mean of 26. 8. The duration of lesion before the visit to the department ranged frorn 6 weeks to 20 weeks, with a mean of 11.9. The lesions in 2 were classified as macule, 3 as papule (1 as moist papule), and 5 as papulo-squamous lesions. The VDRL titer was higher in papular type. Dark fieId examination was performed on all patient and 6 showed positive result. The edidermal changes consist of hyperkeratosis (in 6 cases), parakeratosis (in 5), acanthosis (in 6), elongation of rete ridges (in 8) and exocytosis (in 3). The dermis showed mild to severe perivascular infiltration consist chiefly of lymphoid cells and histiocytic cells (in 10), plama cells (in 7), eosinophils (in 4), neutrophils (in 2), chromatophores (in 4), extra vasation of RBC (in 5), and dilated bload vessels endothelial swellings (in 8). Of particular interest was the finding that plasma cell infiltration is more pronounced at the lower portion of dermal infiltrate and in 3 cases plasma cell infiltration was totally absent. Vascular changes were seen in 8 cases.

BACKGROUND: Vitiligo is riot quite a rare diseasep; it has about 1% prevalence. The cause of vitiligo is not clear, however, in recent studies an autoimmune origin is freqluei itily mentioned. OBJECT: We tried to an lyze some clinical features of vitiligo and relate them with the presence of autoantibodies. MEHTODS: A total of 381 vitiligo patients was included for the analysis of clinical features. A laboratory study included rhumatoid factor, antinuclear antibocoly, antithyroglobulin antibody and antimicrosome antibody. Some 62 patients were examined for opl thmologic changes. RESULTS: One hundred and one(26.5%) of 381 patients exam ned showed at least one of the autoantibodies tested. Twenty nine pateints showed 2 different aitintibodies. The age at aonset of vitiligo in the autoantibody positive group was 6.6 years later than that of the autoantibody negative group. Autoimmune and/or endocrine diseases were more frequinty found among aut.oantibody positive patients. These diseas s included hyperthyroidism, diabetes me litus and alopecia areata. One patient revealed retinal hypoigmentation and showed no autoantibcidics. CONCLUSION: About 9% of vitiligo patients who were autoantiocyte positive had clinical evidence of diseases associated with the autoantibody. However, it is prudent. to xpect that more patients with t.he autoantibody may develop later systemic autoimmune diseases or endocrinopathies. A long term follow-up of these patients seem:, to be very important.

BACKGROUND: At least 30 per cent of diabetics, which is said to comprise over 3% of general population in Korea, have one or more cutaneous complications during the course of the disease. These skin changes may be the consequences of microangiopathy, arteriosclerosis, direct metabolic disturbances and/or the sequelae of chronic therapy. OBJECTIVE: We tried to observe certain cutaneous and nail changes in diabetics and to relate them with systemic complications, blood sugar level and duration of diabetes. METHODS: During the period of 12 months from March, 1992 to February, 1993, a total of 1858 outpatients diagnosed as diabetes mellitus at Eulji General Hospital were examined. RESULTS: The cutaneous manifestations are observed in 79.5% of diabetics examined and cutaneous infections are the most prevalent(52.3%). Pruritus(p<0.01), anogenital pruritus(p<0.01), peripheral dedema(p<0.05) are more common in females and infections, shin spots, finger pebbles(p<0.01) are more common in males. Systemic complications are observed in 50.7% and the cutaneous manifestations are observed more frequently in patients with systemic complications(p<0.05). Shin spots, diabetic foot, peripneral edema diabetic bullosis are observed frequently associated with systemic microangiopathic complications such as retinopathy, nephropathy and neuropathy(p<0.01). There is a significant correlation between blood sugar level and fungal infections and anogenital pruritus(p<0.01). The frequencies of shin spots, diabetic foot and diabetic bullosis increase with the length of time diabetes has been present. Nail changes are observed in 39.6% of diabetics and onychomycosis is the most frequent(34.5%). CONCLUSION: It is suggested that cutaneous shgns especially fungal infections in diabetics are on the increase in Korea. A variety of skin conditions are encountered with diabetes mellitus and the dermatologist may be able to make a significant contribution in the control of diabetes mellitus by identifying skin signs and conditions as diabetic complications.

Between December 18, 1985 and May 31, 1986 at the VD Clinic, Choong-ku Public Health Center, in Seoul, 274 male patients with uncomplicated gonococcal infection, including 124 penicillinase producing Neisseria gonorrhoeae(PPNG) infection, were entered into the study. They were divided randomly into the group A and the group B. In the group A, treated with kanamycin 2g, im regimen, 126 of 137 patients were followed and 86 patients(68.3%) were cured. In the group B, treated with gentamicin 240mg, im regimen, 125 of 137 patients were followed and 78 patients(62.4%) were cured. The cure rates in PPNG urethritis were 63.9%(39/61) in the group A and 50.9%(29/57) in the group B. The cure rates in non PPNG urethritis were 72.3%(47/65) in the group A and 72.1% (49/68) in the group B. No significant difference was observed in cure rates between two groups. It is suggested that. both kanamycin 2g, im regimen and gentamicin 240mg, im regimen is not suitable for a first line treatment for uncomplicated gonococcal urethritis.

Korean Journal of Dermatology 1982;20(4):545-549
A single pedunculated slowly growing tumor was found on the right thigh of a 49 year-old woman. The tumor cells were largely those of eccrine poroma but the degree of the extension of the tumor cell masses, which occupied most of the dermis, were like that of invasive basal cell epithelioma. In addition there were areas where the cells show considerable atypia and dyskeratosis. These histopathological findings were compatible with eccrine poroepithelioma first reported by Mishima and Morioka(1969). The histologic differences between eccrine poroma, eccrine poroepithelioma and eccrine porocarcinoma were discussed.
