Administration of a hyaluronic acid (HA) filler injection is a common aesthetic procedure widely used for facial soft-tissue augmentation. Owing to their low immunogenicity, hyaluronic acid fillers have rarely been linked with serious long-term adverse effects. Although generally safe, reports of adverse events linked to hyaluronic acid filler injection are increasing following its extensive usage globally. We describe the case of a 33-year-old woman who presented with multiple facial nodules at sites of filler injection. To the best of our knowledge, this is the first reported case of facial pseudocyst related to monophasic hyaluronic acid filler injection, in Korea.

Clear cell papulosis (CCP) is a rare skin condition characterized by asymptomatic multiple hypopigmented maculopapules distributed primarily on the lower aspect of the abdomen or along the milk lines in young children. The characteristic histological feature of CCP is the presence of clear cells scattered among basal keratinocytes. We describe the case of a 3-year-old girl with clear cell papulosis. Immunohistochemical staining results were variable based on the different kinds of CEA antibodies. Immunostaining specification of CEA glycoproteins may provide a clue for the differential diagnosis of clear cell papulosis with other diseases such as primary extramammary Paget's disease.

RESUMEN
BACKGROUND: Hand eczema is one of the most common skin disorders and negatively affects quality of life. However, a large-scale multicenter study investigating the clinical features of patients with hand eczema has not yet been conducted in Korea. OBJECTIVE: To identify the prevalence of various hand diseases, which is defined as all cutaneous disease occurring in hands, and to investigate the clinical features of patients with hand eczema and the awareness about hand eczema in the general population and to compare the prevalence of hand eczema between health care providers and non-health care providers. METHODS: To estimate the prevalence of hand diseases, we analyzed the medical records of patients from 24 medical centers. Patients were assessed by online and offline questionnaires. A 1,000 from general population and 913 hand eczema patients answered the questionnaire, for a total of 1,913 subjects. RESULTS: The most common hand disease was irritant contact dermatitis. In an online survey, the lifetime prevalence of hand eczema was 31.2%. Hand eczema was more likely to occur in females (66.0%) and younger (20~39 years, 53.9%). Health care providers and housewives were the occupations most frequently associated with hand eczema. Winter (33.6%) was the most common season which people experienced aggravation. The 63.0% and 67.0% answered that hand eczema hinders their personal relationship and negatively affects daily living activities, respectively. CONCLUSION: Hand eczema is a very common disease and hinders the quality of life. The appropriate identification of hand eczema is necessary to implement effective and efficient treatment.

Cutaneous metastasis from gastric adenocarcinoma is uncommon, and the eyelid is a rare metastatic site. Three patterns of clinical presentation of eyelid metastasis have been described: nodular, infiltrative, and ulcerated. The infiltrative pattern, also known as an inflammatory diffuse pattern or mask-like metastasis, can be easily misdiagnosed as cellulitis or contact dermatitis. Here, we report a case of gastric adenocarcinoma in a 75-year-old man who presented with a localized erythematous plaque on his eyelid that developed four months earlier. The patient had been treated with an antimicrobial agent owing to suspicion of preseptal cellulitis. Gastric adenocarcinoma metastasis was diagnosed on the basis of histopathological examination and immunophenotyping (i.e., cytoplasmic epithelial membrane antigen, cytokeratin- 7, cytokeratin-20, and carcinoembryonic antigen). For patients with malignant neoplasms, persistent skin lesions similar to cellulitis or contact dermatitis should be suspected of metastasis derived from an internal malignancy, even for very rare sites of metastasis.

RESUMEN
BACKGROUND: Fractional laser resurfacing treatment has been extensively investigated and is widely used. However, the mechanism underlying its effects is poorly understood because of the ethical and cosmetic problems of obtaining skin biopsies required to study the changes after laser treatment. OBJECTIVE: To evaluate the usefulness of human skin explants for the investigation of fractional photothermolysis. METHODS: Full-thickness discarded skin was treated in 4 ways: no treatment (control), fractional carbon dioxide laser, fractional Er:YAG laser, and fractional 1,550-nm erbium-doped fiber laser. Both treated and non-treated skin samples were cultured ex vivo at the air-medium interface for 7 days. Frozen tissue was sectioned and stained with hematoxylin & eosin for histologic examination and nitro blue tetrazolium chloride for viability testing. RESULTS: Skin explants cultured for up to 3 days exhibited histologic changes similar to those observed in in vivo studies, including microscopic treatment zones surrounded by a thermal coagulation zone, re-epithelialization, and formation of microscopic epidermal necrotic debris. However, the explant structure lost its original form within 7 days of culture. The viability of skin explants was maintained for 3 days of culture but was also lost within 7 days. CONCLUSION: The skin explant model may be a useful tool for investigating the immediate or early changes following fractional photothermolysis, but further improvements are required to evaluate the long-term and dermal changes.

RESUMEN
Imatinib mesylate (Gleevec(R)) is a small-molecule inhibitor that selectively inhibits the tyrosine kinase family, including mutated KIT oncoproteins in gastrointestinal stromal tumors (GIST). However, cutaneous reactions to imatinib are common and occur in 7.0% to 88.9% of patients. Nonspecific skin rashes, facial edema, and pruritus are the most common adverse reactions. However, development of psoriasiform drug eruption owing to the drug has rarely been reported. Herein we report on a 66-year-old male patient with GIST who had taken imatinib (400 mg/day) for 2 months. He developed erythematous scaly macules and papules on the trunk and extremities. Histopathological findings were compatible with a psoriasiform drug eruption.
