BACKGROUND: After the development of the Q-switched lasers, it was possible to remove tattoos without causing scarring. Currently, Q-switched ruby lasers, Q-switched Nd: YAG lasers and Q-switched alexandrite lasers are used selectively to treat tattoos. The objective of this study was to determine the difference of effectiveness aceording to color, site and duration in removing tattoo pigments by the alexandrite laser. MATERIALS AND METHODS: 30 tattoos were treated with a Q-switched alexandrite laser(model IL-l, Candela Laser Corporation. Wayland. U.S.A.). Pretreatment evaluation included a clinical desrviption of the site, color, duration and photographs were taken. The effects were examined by fether photo graphs and telephone follow-up. The response was expressed as the percentage area cleared of the tattoo. The clearance was graded as follows: clear, >95%; excellent, 76-95%; good, 51-75%; fair, 26-50%; poor < 25%. The occurence of adverse events were also examined. RESULTS: 1""he results are summarized as follows: 1. Treatment with fluences that ranged from 6.0-8.0J/cm2 was given on average 1.7 times and better results were achived than expected in 80% of all patients with tattoo. 2. The effectiveness of laser therapy correlated with the number of treatments. 3. After 1 laser session, tattoos of black and darkblue showed better results than light blue in terms of color. 4. After 1 laser session, the sites of tattoos on upper extremitise showed better results than those of the eyebmw, eyeline and face. 5. Differences in duration after 1 laser session were not seen. 6. Hyperpigmentation in 2 cases and bulla formation in 1 case occurred and all complications had ceased after a few months. CONCLUSION: The alexandrite laser is an effective treatment for cosmetic, general and traumatic tattoos with a low incidence of significant adverse effects and provides excellent cosmetic results.

BACKGROUND: Propioriacterium acnes plays an importantol in the development of inflammatory acne, and inflarnmatory lesions are improved by oralnc topical antibiotics. But as Pacnes frequently develop resistance to antibiotics in patients neing long term systemic antibiotic therapy, the theravuti effects diminish, and eventually thay fails. OBJECTIVE: The purpose of this study is to evaluate theerral susceptability of P. acnes to antibiotics and the difference in the MIC depending on the of oral and/or topical antibiotics, therapeutic effects and disease duration in patients with acie ulgaris. METHODS: We used twenty six strains of P. acnes which were obtained from patients with acne and performcd suseptibility testing for antibiotics usir the E test procedure. RESULTS: 1. The growth of P. acnes was completely inhibited by e ythromycin and chloramphenicol at concentrations of 0.023ug/ml and 0.064ug/ml, respectively cefoxitin at 0.094ug/ml, and by tetracycline and clindarnycin at 0.190 ug/ml. 2. P. acnes was mot susceptible to erythromycin, and olwed by chloramphenicol, cefoxitin, tetracycline, clindamycin in order of decreasing susceptibilit . 3. There were no significant differences in the MIC in reat in to previous antibiotic treatment. 4. For tetracycline, The MIC was significantly lower(p<0.01) in patients who improved after treatment. 5, For tetracycline and chloramphenicol, the MIC was grficantly lower(p<0.05) in patients with less than 2 years disease duration. CONCLUSION: The susptibility of antibiotics for P. acneias highest in erythromycin. There were no significant differences in the MIC in relation to prvious antibiotic treatment, and for some antibiotics the suseptibility was low in patients who dill not show clinical improvement or who had long disease duration.

We report two cases showing typical clinical features of subcutaneous granuloma annulare. Clinically, rapidly growing non-tender subcutaneous nodules developed on the scalp of healthy children without histories of trauma or infection. Histopathologically, collagen degeneration surrounded by histiocytes and lymphocytes in a palisading arrangement were seen in the deep dermis and subcutaneous layer. The foci of degeneration contained pale and edematous basophilic mucinous deposits. The skin lesions resolved spontaneously without specific treatment. Subcutaneous granuloma annulare should be considered in the differential diagnosis of children presenting with soft tissue masses.

Membranous lipodystrophy is a peculiar type of fat necrosis, present in patients with various types of skin diseases. It is charaeterized by the presence of microcysts and macrocysts lined by amorphous eosinophilic material with a crenelated arabesque appearance and microgranules in the subcutis with massive fat necrosis. The eosinophilic lining and microgranules stain positively with periodic acid-Schiff, are resistant to diastase, and also stain with Sudan black B. We report three cases of subcutanous membranous lipodystrophy in patients with erythema induratum, posttraumatic panniculitis and morphea with typical clinical and histopathologic findings.

We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

BACKGROUND: Acne is a common chronic disease which most frequently affects the face. This visibility is a major cause for concern in affected individuals. OBJECTIVE: The purpose of this study was to investigate the quality of life of patients with acne. METHODS: We interviewed 130 acne patients, and determined the impact of acne on the quality of life with a questionnare. RESULTS: Among 130 cases of acne, the numbers of male and female patients were 52(40.0%) and 78(60.0%) respectively, and tbe mean age was 21 years. There was no difference between the sexes in the quality of life criteria used. The scores of social criteria of patients older than 20 years were significantly higher than thme of patients younger than 20 years. The severity of facial acne was correlated with the severity of chest acne but not with that of back acne. The severity of chest acne was correlated with that of back acne. The severity of facial acne was correlated with the scores of the physical, social and psychological criteria, and the severity of chest acne was correlated with that of physical and social criteria. However, the severity of back acne was not correlated with those of any of the criteria. The psychological well-being of the patients was moderately or highly affected by the acne more often than the other criteria. CONCLUSION: Acne has a substantial impact on the quality of life. The practical use of these indices are: (1) reveal areas of particulur concern in patients with acne; (2) to identify individuals who may require more intensive treaiment; and (3) to give a patient oriented inforrnation on the quality of life expected.

Angioma serpiginosum is a rare acquired naevoid disorder, characterized by minute red or purple punta that are frequently arranged in serpiginous patterns in the lower extremities and buttocks. It usually begins in childhood and is more common in females. Histopathologically, thin-walled capillaries in the dermal papillae and the superficial reticular dermis are widely dilated without extravasation of red blood cells. We report a case of angioma serpiginosum on the lateral aspect of the right arm along the lines of Blaschko in a 36-year-old woman.

The anti-inflammatory activity of a corticosteroid may mask the contact allergic reaction it is causing. This may be an important reason why contact allergy to corticosteroids has often been missed. A simple persistent aggravation of a dermatitis in a patient treated with one or more topical corticosteroids is sufficient to raise a suspicion of corticosteroid hypersensitivity. A 23-year-old male visited our department for the evaluation of his aggravated pruritic oozing erythematous papules, scales and edema of the face. Previously, he was treated with Dermatop ointment and Plancollotion. A Patch test showed positive reactions to prednicarbate 10%, 1%, hydrocortisone-17-butyrate 10%, and triamcinolone 10%. We conclude prednicarbate in Dermatop ointment, hydrocortisone-17-butyrate in Plancol lotion to be the etiological agents.

Reticulohistiocytoma, a rare form of non-Langerhans cell histiocytoses, usually presents it-self as a single cutaneous nodule mainly on the head and neck of young men without associated arthritis. We describe an 18-year-old male patient with a red dome-shaped nodule of 2 months' duration on the scalp. Histologic examination of the excised mass revealed numerous large, mononucleated or multinucleated histiocytes with abundant eosinophilic, finely granular cytoplasm having a ground-glass appearance. Immunohistochemical staining was positive for vimentin, lysozyme, and factor XIIIa, supporting a dermal dendrocyte lineage. Ultrastructurally, large mononuclear or multinucleated cells exhibiting numerous peripheral villi contained pleomorphic cytoplasmic inclusions, fatty droplets and dense bodies. Our clinicopathologic findings support the concept that reticulohistiocytoma is a variant of adult xanthogranuloma.

Eosinophilic panniculitis is characterized by a prominent infiltration of numerous eosinophils in subcutaneous fat, and has been identified in patients with a variety of associated clinical conditions. A case of eosinophilic panniculitis in a 20-year-old woman with a history of atopic dermatitis is reported. She later developed superior sagittal sinus thrombosis, and we stress the importance of systemic evaluations in patients with eosinophilic panniculitis.
