BackgroundChronic hand eczema (CHE) tends to be refractory to conventional therapy. Previous clinical trials have found that a 24-week treatment course of oral alitretinoin is effective and well tolerated for CHE treatment.ObjectiveThe aim of this study was to investigate the efficacy and safety of oral alitretinoin in Korean CHE patients.MethodsA total of 27 patients with moderate to severe CHE took 30 mg of alitretinoin daily for 12 weeks. The primary efficacy parameter was the physician's global assessment (PGA). The response was defined as a patient being "clear" or "almost clear" of disease. The secondary efficacy parameters were the modified total lesion symptom score (mTLSS) and the patients' global assessment (PaGA). All adverse events and laboratory abnormalities were recorded during the treatment period.ResultsAlitretinoin led to CHE symptom improvement in 44.4% of patients. The PGA, mTLSS, and PaGA scores correlated well with each other. Reported adverse events were typical retinoid class effects and headache was the most common.ConclusionTaking 30 mg of oral alitretinoin daily for 12 weeks was found to be effective in treating Korean patients with CHE, compared with the 24 week-treatment shown in previous studies.

As demand for a youthful appearance has increased, various techniques for face lifting and contouring have been used to reduce excess fat deposition and improve skin laxity. Recently, radiofrequency (RF)-assisted lipolysis and liposuction (RFAL) has been introduced for body and face contouring. This study aimed to evaluate the clinical improvement and safety of a new RFAL device for face lifting and contouring. A prospective study was conducted in 20 Korean patients who underwent an internal real-time thermosensing monopolar RFAL procedure. Prior to treatment and 12 and 24 weeks after treatment, digital photographs were taken, and the degree of improvement as measured by investigators and patients was recorded. Skin elasticity was measured using a Cutometer (CT575, Courage and Khazaka®, Cologne, Germany). Safety profiles were also evaluated at each visit. Results showed favorable improvement in skin laxity and fat deposition. Both investigators' evaluations and patients' evaluation showed significant improvement between 12 and 24 weeks. Although the changes in skin elasticity measured by the Cutometer were not statistically significant, all three treated regions showed a trend toward improvement. No major side effects such as infection or burn were observed. The internal, real-time thermosensing monopolar RFAL device showed clinical efficacy and safety. After further studies with more patients and longer follow-up periods, internal real-time thermosensing monopolar RF devices might become one of the popular treatment options for face lifting and contouring.

Although squamous cell carcinoma (SCC) is the second most common nonmelanoma skin cancer, clinicians have difficulty diagnosing SCC of the toe because its clinical features can mimic other less serious diseases. Clinicians are especially prone to misdiagnose SCC of the toe as diabetic foot ulcer in patients with diabetes mellitus because of the clinical similarity of the 2 ailments. SCC of the toe is generally considered to have a low risk of metastasis. Locoregional or distant metastases without bone or tendon involvement are particularly rare. The authors report here an interesting case of rapidly spreading SCC of the toe with metastasis to multiple lymph nodes and cancer-related lymphedema. Physicians should be aware of the possibility of malignancy when they encounter chronic and recalcitrant ulcerative lesions of the digits.

Pyoderma gangrenosum (PG) is a rare, relapsing cutaneous disease with 4 distinctive clinical manifestations: ulcerative, bullous, pustular, and vegetative lesions. It mainly occurs in adults and is frequently associated with systemic diseases, most commonly inflammatory bowel disease, rheumatologic disease, or hematological dyscrasias. However, there have been no previous reports of PG in a patient with hereditary spherocytosis, a common inherited hemolytic anemia. We report here a unique case of PG in a 15-year-old boy with underlying hereditary spherocytosis.
