Morganella morganii에 의해 유발되었다고 사료되는 피부 궤양

Morganella morganii, a gram, negative rod is often regarded as an opportunistic, secondary invader rather than a primary pathogen on the skin. It has been isolated from blood, sputa, and pus from patients with respiratory tract and wound infections or with bacteremia. A 2-year-old boy presented with erythematous ulcerative lesions on the cheeks and left knee which had a tendency to superficial scarring. The organism isolated from the ulcer displayed a biochemical char acteristics typical of Morganella morganii. The lesions responded well to systemic antibiotic therapy with amikacin and carbenicillin, which were recognized as effective drugs in in vitro sensitivity testing.

Angiomatoid fibrous histiocytoma(AFH) is a rare cutaneous tumor showing distinctive clinical and histological features. It occurs as a slowly growing nodular or cystic mass of the dermis or subcutis, on the extremities of children and young adults. One of the most characteristic histological features is the presence of irregular blood-filled cystic spaces. The histogenesis of AFH is still controversial, with histiocytes, fibroblasts and endothelial cells all having been proposed as the main proliferating cell. A twenty-year-old woman was seen for a nodular lesion on the right forearm of 1 yeat duration. Initially, the lesion was asymptomatic and had recently increased slightly in size. The excisional biopsy specimen showed a relatively well circumscribed tumor mass in the dermis and subcutis. There were large blood-filled cystic spaces and areas of hemorrhage in addition to the solid sheets of fibroblast-like and histiocyte-like cells. Xanthoma cells, siderophages and Touton type giant cells were also present. On immunohistochemistry, most of the tumor cells strongly expressed histiocyte markers, although some of the tumor cells showed positive reactions for smooth muscle actin, muscle specific actin, desmin, and factor Ⅷ-associated antigen.

We experienced a case of arteriovenous hemangioma showing Dariers sign on the forehead of a 43-year-old man. He presented with a single, 1 * 1.5cm sized, violaceous, asymptomatic nodule with a history of an intermittent wheal at the lesional site. This skin lesion showed Dariers sign clinically and proliferation of mast cells histopathologically with the punch biopsy specirnen suggesting urticaria pig- mentosa. Howerer, we could diagnose it as a arteriovenous hemangioma on complete excision, as the specimen showed arteriovenous proliferation with increased mast cells in a perivascular pattern. This case showed confusing clinical signs and showed the importance of complete excision for the diagnosis of a small skin tumor especially when a vascular proliferating tumor is suspected.

Calcium Gluconate 정맥내 투여에 의해 발생한 피부석회증

We report a case of calcinosis cutis following administration of 10% calcium gluconate, used for the treatment of a hypocalcemic seizure in a 5-week-old neonate. After administration of 10% calcium gluconate, subcutaneous induration developed at the infusion site. The histopathological findings taken from the dorsum of the left foot showed multiple foci of calcium deposits with infiltration of epitheloid histiocytes between collagen bundles and foreign body giant cells phagocyting calcific granules throughout the reticular dermis and subcutis.

The isomorphic response of Koebner is a well-known phenomenon commonly associated with psoriasis, but it has been also described in conjuction with a host of other disorders. However it has seldom been associated with necrobiosis lipoidica diabeticorum, a rare skin manifestation of diabetes mellicuts. In this report, we describe a 59-year-old woman who developed necrobiosis lipoidica diabeticorum on the left shin where a mosquito had bitten her 2 months ago. Four months ago, she was diagnosed as necrobiosis lipoidica diabeticorum on the right forearm and shin by biopsy and the lesions were improved with corticosteroids intralesional injection. The lesions were asymptomatic and had grown slowly. Histopathological findings showed a large palisading granulomas composed of histiocytes, epithelioid cells and areas of necrobiosis of collagen with multinucleated giant cells. Van Gieson stain showed decreased and fragmented elastic fibers and there were no deposits of mucin in the necrobiotic areas. The lesions were improved with triamcinolone acetonide intralesional injection and there was no recurrence during 4 months. (Korean J Dermatol 2000;38(2):245~248)

Purpose: To compare the change of visual acuity and NIBUT after watching smart-phone in 1 hour under low intensity of illumination. Methods: 50 subjects (male 22, female 28) aged 20`s years old (20.7±2.4 years) who do not have eye disease and have a good eye condition were participated for this study. Objective refraction, corrected distance visual acuity and NIBUT were measured before and after watching smart-phone (Galaxy 2, Samsung, KOREA) under low intensity of illumination (0 lx.) Objective refraction was carried out using autochart project (CP-1000, Dongyang, Korea), phoropter (VT-20, Dongyang, Korea) and auto refractor-keratometer (MRK-3100, Huvitz, Korea). Results: Refractive error was changed from -3.20±2.00 D to -3.38±2.00 D (p=0.006) and corrected distance visual acuity was changed from 0.93±0.08 to 0.91±0.10 (p=0.000) and NIBUT was changed from 10.48±7.00 seconds to 10.29±6.47 seconds (p=0.761) before and after watching smart-phone under low intensity of illumination. Conclusions: Continuous watching smart-phone under low intensity of illumination lead to temporal change of distance visual acuity and suitable rest may reduce the influence of distance visual acuity and tear safety.
