Pseudo-Kaposis sarcoma is a self-limited process associated with vascular malformations, without the neoplastic character of real Kaposis sarcoma. In most cases, it has been associated with an underlying congenital arterial venous fistula and chronic venous insufficiency, We present a case of Pseudo-Kaposis's sarcoma developing after plagment of arteriovenous fistula for hemodialysis in a patient wiith chronic renal failure and review cases reported in articles.

Pressure alopecia can occur after prolonged pressure on the scalp with the head fixed in one position. We have repor ted 5 cases of pressure alopecia, occurring over the contralateral temporoparietal 1 area after tympanomastoidectomy due to chronic ot.itis media. Total times of operations were from 4 hours to 7 hours. Four of the 5 patients experienced scalp pain during the early postoperative period and one of them showed large bulla formation. Loss of hairs followed between the 14th and 36th postoperative day, and new hairs began to grow 2 or 3 months after the operation.

We report a case of bullous scabies in a 81-year-old male patient. He had severe pruritic, multiple tense bullae on erythematous base with erosions and crusts from which scabies mites were identified. Histopathologic findings(H&E) revealed subepidermal bulla and direct immunofluorescence showed linear deposition of IgG and C3 at the dermoepidermal junction and linear IgG, C3 deposition at the dermal side of the salt split skin test. However, no EBA or BP antigens were detected. Although skin lesions improved after antiscabietic and oral steroid treatments, pruritic bulla developed repeatedly with scabies reinfestation or discontinuation of oral treatment.

A bolster, simply defined, is any device used to support or cushion. In surgery, bolsters have been used under sutures to reduce skin and subcutaneous tension. Bolsters function to reduce the potential for necrosis and laceration by distributing the wound closure tension over a broader surface area. Pexing stitich is placed between the mobilized tissue and the deep fascia and periosteum to prevent the secondary motion of closure from disrupting anatomic landmarks and moveable structures. The technique aids in obtaining linear closures, prevents distortion of free margins, prevents tenting across concavities, and fixes the closure line at the junction of cosmetic units. Standard treatment of lipoma commonly includes incision with extrication or elliptical excision. Unfortunately, these treatments often elicit a large scar. Using pressure technique, risk of hemorrhage and infection may be minimized secondary to the decreased degree of invasion. In cosmetically sensitive areas, this technique is an effective and aesthetically pleasing method for removal of lipoma.

We report two cases of unusual manifestations of secondary syphilis accompanied by human immunodefiency virus infection. The first case is a 57-year-old heterosexual man with human immunodeficiency virus (HIV) seropositivity and unusual manifestations of secondary syphilis. The second case is a 28-year-old man presented with unusual cutaneous lesions of secondary syphilis. The following laboratory tests showed that the patient was seropositive for HIV. Both patients' cutaneous lesions resembled those of a patient with Reiter's syndrome such as keratoderma blennorrhagicum and circinate balanitis. The VDRL test of the first case showed the prozone phenomenon (false-negative in undiluted specimen).

A poroma is usually described as a benign neoplasm arising from ductal epithelium of eccrine gland. However, in recent years there have been several reports on poromas featuring with combined sebaceous, follicular, and ductal differentiation, and thus establishment of this separate disease entity, "apocrine poroma" may well be justified considering the common embryologic origin of folliculosebaceous-apocrine unit. In our case, the tumor presented as a dark red nodule on the pubic area, being revealed as poroid neoplasm with folliculosebaceous components embedded in the lobules. Immunohistochemically, poroid cells stained with lysozyme. Taking the immunohistochemical staining results as well as the histopathologic findings of folliculosebaceous differentiation into consideration, we have concluded that this tumor is a case of an "apocrine poroma".

Verrucous carcinoma is a variant of well-differentiated squarmous cell carcinoma. Although this tumor is well-documented in the oral cavity, its occurrence on the glans penis is rare. It is a relatively nonaggressive tumor which seldom metastasizes to the resional lymph node or distantly. With proper treatment, the prognosis is excellent. We have experienced a case of verrucous carcinoma arising on the glans penis with the previous insertion of paraffin and penile prosthesis for the augumentation of penis, which was treated with total phallectomy. We report this case with a review of literature.

BACKGROUND: Lichen striatus(LS) is an uncommon dermatosis that generally affects children. LS can usually be identified by clinical history and histology of typical lesions. However, the clinical manifestations and the histologic features are diverse. OBJECTIVE: The aim of this study is to investigate clinical and histopathologic features of LS in Koreans. METHODS: Total 20 patients were included in this study. Data complied were sex, age, duration, distribution, symptoms, course and some histopathologic findings including hyperkeratosis, acanthosis, dyskeratosis, basal degeneration, perivascular lymphocytic infiltration, lichenoid infiltration and eccrine sweat gland inflammation. Seventeen cases were studied further by immunohistochemistry for interleukin(IL)-1beta to understand the biological basis of the disease. RESULTS AND CONCLUSIONS: 1. It was observed predominantly in females as the sex ratio of 1: 2.3. The mean age was 5.5 years and the mean duration was 17.7 months. 2. Most of patients were asymptomatic, but only five patients complained of mild itching. 3. It occured most frequently in the lower(11 cases), upper extremities(6 cases), axilla(1 case), anterior chest(1 case) and multiple location(1 case). Twelve cases were consisted of erythematous papules, and the rest appeared hypopigmented macules. 4. The lesions of 9 of 10 patients were almostly cleared in one year. Five of 9 were consisted of erythematous papules and four hypopigmented macules. One who had no change was consisted of hypopigmented macules. Therefore, there was no significant difference of prognosis between two groups. 5. Histologic examination revealed hyperkeratosis(65%), acanthosis(70%), parakeratosis(50%), exocytosis(95%), spongiosis(55%), dyskeratosis(70%), basal degeneration(90%) in epidermis, and colloid body(35%), lichenoid infiltration(65%), perivascular lymphocytic infiltration(95%) and eccrine sweat gland inflammation(50%) in dermis. 6. There was no significant difference between the papular group and the macular group, except parakeratosis and spongiosis, which were increased in the papular group as compared with the macular group. 7. IL-1beta was expressed diffusely in keratinocytes, endothelial cells, hair follicles and eccrine sweat glands. IL-1beta immunoreactivity was expressed in the entire epidermis in 15 of 17 cases. Most of the eccrine sweat glands showed intense immunolabeling in 12 of 17 cases. In contrast, only 2 cases of lichen planus were positive for epidermis and only 1 case for eccrine sweat gland. Therefore, we think that it is helpful for discriminating two diseases immunohistochemically.

BACKGROUND: Xanthelasma palpebrarum is the most common cutaneous xanthoma. Although xanthelasma is a type of xanthoma, a half of patients in most series are known to be normolipemic. OBJECTIVE: This study is an attempt to elucidate the clinical and pathologic features of xanthelasma in Korea and to know the clinical significance of xanthelasma, especially suggested role as a marker for hyperlipidemiae and increased risk for cardiovascular diseases. METHOD: Thirty seven cases of xanthelasma were clinially and pathologically analyzed. Incidence of abnomal lipid profiles and cardivascular diseases were compared with those of control group using logistic regression statistics. RESULTS: 1. The incidence of xanthelasma was 0.09% of the total number of dermatologic patients. 2. The ratio between male and female was 1: 1.8 and the mean age was 52.4 years (range;17-71 years). 3. Clinically, it typically presented as yellow or orange papules on the inner canthus of both upper eyelids. 4. The incidences of abnormal lipid profiles(hyperlipidemia and dyslipoproteinemia) are 42.4-44.0%. The levels of total cholesterol and low density lipoprotein-cholesterol were increased significantly. The incidence of the cardiovascular diseases was 16.2%, which was not statistically different from that of control group. 5. Histopathologic findings of 23 cases showed masses of foam cells in the upper dermis accompanied with sparse inflammatory cells and few giant cells. CONCLUSION: Xanthelasma seems to help to identify persons with abnormal lipid profiles which are risk factors of cardiovascular diseases and we recommand examination of lipid profiles in patients with xanthelasma.

BACKGROUND: Skin temperature at UV radiation exposure influences acute skin reaction such as erythema and pigmentation. As most biochemical systems are affected by temperature, thermal change preceding or following UV exposure could influence the responses in the way to cause vascular blood flow and change the inflammatory response OBJECTIVE: To investigate the influence of thermal change on UV-induced erythema and pigmentation by using objective and quantitative method METHODS: A sunlight fluorescent sunlamp (Waldmann UV 800) was used as a UV light source. Multiple sites of the lower back were irradiated with an increasing doses of UV, which were preceded or followed by heating or cooling. With a reflectance spectrophotometer, we assessed erythema and melanin indices at control, 0.1, 0.5, 1.0 and 2.0 MED dose-exposed sites. RESULTS: Compared with the only UV-exposed group, skin warming or cooling groups generally showed elevated acute erythema reaction with higher erythema indices. However, thermal changes preceding or following UV exposure had little effect on pigmentation except the post-warming group with UV exposure of 2 MED dose after 2 weeks. Our results indicate that altering the skin temperature modulates the degree of UV-induced erythema, but generally not skin pigmentation. CONCLUSION: The results in this study show that environmental factors such as heat or cooling have modulating effects on UV-induced skin reaction. These interactions should be considered when dealing with the effects of natural sun exposure or phototherapy.
