Juvenile xanthogranuloma is a congenital or perinatal tumor, 1 to 2 cm in diameter, usually located on the head. The extracutaneous lesions can occur on the eye, the lung, the epicardium, the oral cavity or the testicles. Subcutaneous form of juvenile xanthogranuloma has been reported very rarely in the literature. We report a unique case of a subcutaneous juvenile xanthogranuloma that showed 4 × 4 cm sized plaque and located on the extremity of 9-year-old girl.

3.A Case of Eccrine Angiomatous Hamartoma.
Korean Journal of Dermatology 2003;41(7):951-953
Eccrine angiomatous hamartoma is a rare condition characterized histologically by increased numbers of eccrine structures and numerous capillary channels. It may be congenital or appear later in childhood. It rarely arises during puberty or adulthood. We report a case of eccrine angiomatous hamartoma on the left shoulder in a 34-year-old man. The patient presented with asymptomatic, dome-shaped, about 3X2.5 cm, reddish telangiectatic nodule on the left shoulder. Histological examination showed an increased numbers of eccrine sweat glands and vascular structures.

Perfluoroalkyl substances (PFAS) are widely used in industry and daily life due to their useful properties. They have a long half-life, accumulate in the body, and there is evidence that they are associated with biomarkers of lipid metabolism and liver damage. This may suggest non-alcoholic fatty liver disease (NAFLD) caused by PFAS. However, since there has been no study analyzing the relationship between PFAS and NAFLD in the entire population in Korea. We sought to confirm the relationship between serum PFAS concentration and NAFLD prevalence in Korean adults using the Korean National Environmental Health Survey (KoNEHS) cycle 4. The study was conducted on 2,529 subjects in 2018–2019 among KoNEHS participants. For the diagnosis of NAFLD, the hepatic steatosis index (HSI) was used, and the geometric mean and concentration distribution of serum PFAS were presented. Logistic regression was performed to confirm the increase in the risk of NAFLD due to changes in PFAS concentration, and the odds ratio and 95% confidence interval (CI) were calculated. In both adjusted and unadjusted models, an increased odds ratio was observed with increasing serum concentrations of total PFAS and perfluorooctane sulfonate (PFOS) in the non-obese group. In the adjusted model, the odds ratios for serum total PFAS and PFOS were 6.401 (95% CI: 1.883–21.758) and 7.018 (95% CI: 2.688–18.319). In this study, a higher risk of NAFLD based on HSI was associated with serum total PFAS, PFOS in non-obese group. Further research based on radiological or histological evidence for NAFLD diagnosis and long-term prospective studies are necessary. Accordingly, it is necessary to find ways to reduce exposure to PFAS in industry and daily life.

The cerebral vasospasm which often accompanies a subarachnoid hemorrhage from a ruptured intracranial aneurysm is one the chief reasons for morbidity and motarlity. Although the phenomenon still needs clarification, experimental evidence has indicated that alpha-blocking agents can modify this blood-induced spasm. A disappointing experience with these agents led to a clinical trial of the beta-adrenergic drug isoproterenol. In 1975 Sundt reported a good final result with the use of isoproterenol and lidocaine hydrochloride in the treatment of cerebral ischemia attributed to progressive vasospasm after a subarachnoid hemorrhage in human beings. We have reported our experience with the use of isoproterenol and lidocaine hydrochloride in 5 such cases. 3 were treated preoperatively and 2 postoperatively. Experience suggests that the drug regimen reported is useful when institute early after the onset of symptoms and is safe with proper monitoring techniques. The symptomatology of cerebral vasospasm, the reationable for this form of therapy, and the pharmacology of the drugs were discussed.

Seminoma is one of the most radiosensitive solid tumors. However, the survival of patients with clinically advanced stages B3 and C disease is poor. Most of the failures of treatment in advanced stage seminoma, however, come from systemic diseases outside radiation fields or are secondary to unrecognized non-seminomatous elements. Therefore adjuvant systemic chemotherapy is essential for proper treatment of three patients. Recently we experienced a case of advanced stage seminoma treated with radical inguinal orchiectomy followed by systemic chemotherapy with good result.

We report a case of trichilemmal carcinoma in a 82-year-old man who presented an ulcerative tumor. Initially, a crusted mass was observed on the scalp and with subsequent removal of the crust, purulent and ulcerative lesion was seen. After treatment with sensitive antibiotics for 8 days, purulent discharge was markedly decreased in the lesion. Histopathologic findings showed clear cells tumor with trichilemmal keratinization. The tumor cells stained positive to PAS, sensitive to diastase and showed negative findings to CEA, EMA and S-100.
