Cytomegalovirus (CMV) is a major cause of morbidity and mortality in immunocompromised patients. CMV can cause pneumonia, retinitis, gastrointestinal ulcers, and widely disseminated disease, but cutaneous CMV is rare. We report two cases of cutaneous CMV infection presenting as perianal ulcers. A 54 year-old male who had liver transplantation and a 72-year-old male, who was treated with chemotherapy for angioimmunoblastic T-cell lymphoma, presented with perianal ulcers and had systemic symptoms of CMV infection with CMV antigenemia. They had multiple ulcerations with erythematous bases on the perianal area, and histopathologic examinations showed large atypical cytomegalic cells in the dermis, and immunohistochemical stains, with the anti-CMV antibody showed positive reactions.

OBJECTIVE: To obtain clinically useful data regarding prenatal diagnosis, proper antepartum counseling and obstetric management in pregnancies with fetal dysplastic kidney disease. METHODS: We retrospectively reviewed 13 cases of MCDK(Multicystic dysplastic kidney) and PCDK(Polycystic dysplastic kidney), diagnosed by antenatal ultrasound and delivered from June 1994 through July 1999 at Ajou University School of Medicine, Department of Obstetrics and Gynecology, with regard to prenatal ultrasonographic findings, perinatal outcomes, maternal complications and associated fetal anomalies. RESULTS: The incidence of MCDK and PCDK was one in 1,066 and one in 2,398 births, respectively. Of the 9 cases of MCDK, one case was terminated due to severely associated anomaly, and 6 cases were delivered by spontaneous labor or pitocin induction at term, of which 1 case was delivered by pitocin induction at 36 weeks gestation due to intrauterine fetal death. Two cases were delivered by cesarean section. There were no neonatal deaths in 7 cases of MCDK and they have been followed up to date, and alive. Of the 4 cases of PCDK, 3 cases were terminated by induced abortion or induced vaginal delivery, and 1 case was delivered by cesarean section, which was combined with hypertrophic cardiomyopathy, and the baby died within 24 hours after birth. Perinatal complications consisted of small for gestational age, urinary tract infection, hydronephrosis, acute respiratory failure, acute renal failure, periventricular hemorrhage and laryngomalacia in the neonatal period. CONCLUSION: It is suggested that antenatal ultrasonography and genetic analysis to evaluate accurate diagnosis and associated anomalies should be performed to manage and councel properly the pregnancies with fetal dysplastic kidney disease.

Cutaneous leiomyoma is a benign tnmor originating from smooth muscle fibers which are derived from arrector pili muscle, media of blood vessels and dartoic muscle of scrotum, vulvar, or nipple. It is classified into 3 types according to the site of origin, namely pilar leiomyoma, angioleiomyoma and genital leiomyoma. Leiomyoma of the nipple is the less kquent type of cutaneous leiomyoma. We report a case of cutaneous leiomyoma on the nipple in a 53-year-old man.

Inflammatory mediators, such as oxidants, TNF-alpha, and IL-6, play a major role in the systemic response to bum injury It has been known that a continuing inflammatory response cause a sepsis and subsequent multiple organ failure. Recent studies have shown that burn patients receiving recombinant human growth hormone(rhGH) therapy have an improvement of the general condition, but the mechanism by which rhGH exerts its effects has not been clearly understood. The aim of this study was to evaluate the effect of rhGH on the early bum injury. Female Sprague-Dawley rats were divided into four groups : control group, bum group, burn plus rhGH treated group, and rhGH only treated group. Animals were killed at 30min., 3, 6, 24, and 48 hours after treatment. Histology and biochemical changes including malondialdehyde(MDA) content, tissue reduced glutathione(GSH) and catalase activity in the lung and liver, and plasma TNF-alpha and IL-6 levels were examined. Lung histology in the bum plus rhGH treated group showed decreased inflammtory response such as neutrophil and lymphocyte infiltrations, interstitial thickening, and edema compared with the bum group. Liver histology in the bum group revealed mild neutrophil and lymphocyte infiltrations, vacuolization .of hepatocytes, disrupted lobular structures, and dilated sinusoids. But liver histology of the bum plus rhGH was similar to control group. Lung and liver MDA in the burn plus rhGH and rhGH only treated groups were decreased with time compared with the burn group. Lung and liver GSH and catalase activities in the bum plus rhGH and GH only treated groups remained significantly increased compared with the bum group for the 48-hours period. Plasma TNF-alpha levels in the bum group remained elevated for the 48-hours period compared with the bum plus rhGH and rhGH only treated groups. Plasma IL-6 levels in the burn group were significantly increased only at first compared with the bum plus rhGH and rhGH only treated groups. These results suggested that rhGH showed inhibitory effects on the inflammatory cell infiltration and lipid peroxidation in the lung and liver after bum injury. Increased GSH levels and catalase activities seemed to be associated with the antioxidant effect of rhGH. But the inhibitory effect of rhGH on plasma TNF- and R-6 levels was not clearly demonstrated.

Dermatomyofibroma is a rare benign dermal tumor, mainly found in young women. Clinically it can be confused with keloid or dermatofibrosarcoma protuberans. Typical histopathologic features of dermatomyofibroma are sufficiently distinctive to alert histopathologists to consider dermatomyofibroma in the diagnostic process. We report a case of dermatomyofibroma, presenting as reddish plaques and nodules on the buttock of a 2-year-old boy. Histopathologic examination showed fascicles of uniform spindle cells in the reticular dermis, predominantly oriented parallel to the epidermal surface. Immunohistochemical study and electron microscopy confirmed its myofibroblastic nature.

The most common cause of chronic draining sinus tract on the face and neck is the extension of chronic dental infection. The presence of an intermittently draining granulomatous lesion on the face or neck should alert clinicians to the necessity of routine dental examination including radiographic studies. Early correct diagnosis and appropriate dental treatment can pre-vent unnecessary and ineffective antibiotic therapy or surgical treatment. We report a case of a 22-year-old woman with a cutaneous sinus tract on submental region, associated with a periapical abscess of the left mandibular lateral incisor.
