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.

Indeterminate cell proliferations are rarely described in dermatology literature. Indeterminate cells are characterized by positivity for S-100 protein and CD-la, but are distinguished from Langerhans cells by the absence of Birbeck granules. We present a case of congenital indeterminate cell histiocytoma in a 6-day-old male infant. A Skin examination revealed a solitary, erythematous, 6*6cm, superficially crusted, dome shaped papule on his forehead. A Histopathologic examination showed a dense cellular infiltrate in the dermis, below the atrophic epidermis. Frequently, the nucleus demonstrated a single cleft or crease like the shape of a kidney. These cells showed positivity for S-100 protein. Birbeck granules were not found on electron microscopic examination.

We report a case of alopecia mucinosa in a 9-year-old girl. She presented with several papules on an erythematous patch on the right side of the ala nasi, a hairless nodular lesion on the same side of the nasal canal. Histopathologic findings obtained from the nasal canal revealed typical features of alopecia mucinosa, such as reticular degeneration, cystic space formation and mucin deposition in the pilosebaceous follicle. The case displayed no evidence or clinical features of any malignant changes, and we suspect the case to be an acute form of alopecia mucinosa.
