Angioma serpiginosum is a rare acquired naevoid disorder, characterized by minute red or purple punta that are frequently arranged in serpiginous patterns in the lower extremities and buttocks. It usually begins in childhood and is more common in females. Histopathologically, thin-walled capillaries in the dermal papillae and the superficial reticular dermis are widely dilated without extravasation of red blood cells. We report a case of angioma serpiginosum on the lateral aspect of the right arm along the lines of Blaschko in a 36-year-old woman.

BACKGROUND: Drug reactions are common problems in hospital inpatients and outpatients. Reliable diagnosis is essential but often difficult. OBJECTIVE: This study attempts to define the clinical features and causative drugs in the patients with drug eruptions, and to evaluate the diagnostic value of skin tests. METHODS: Sixty one patients with drug eruptions were reviewed clinically. In 18 patients, patch and prick tests were performed using suspected drugs. RESULTS: 1. The highest incidence of drug eruptions was observed in the third and forth decades(44.2%) and there was no sexual prodominence. 2. The most frequent latent peroid was 4 hours to 1 week(49.2%). 3. The common morphological features were exanthematous eruptions(57.3%), urticaria(14.8%) and fixed drug eruptoins(11.5%). 4. The major causative drugs were antibiotics(cephalosporin, ampicillin), antipyretics/anti-inflammatory analgesics(aspirin, piroxicam) and CNS depressants(diphenylhydantoin). 5. Clinical manifestations according to possible causative drugs were as follows; exanthematous eruptions by antibiotics, antipyretics/analgesics, herbs, CNS depressants, propylthiouracil and captopril; urticaria by antibiotics and herbs; fixed drug eruption by sulfonamide, antipyretics/analgesics and phenobarbital; acneiform eruptions by diphenylhydantoin and isoniazid; Stevens-Johnson syndrome by ampicillin, sulfonamide, aspirin and piroxicam, erythema nodosum by sulfonamide, and lichenoid drug eruptions by propylthiouracil. 6. Positivity to patch and prick tests was shown in 2 of the 18 patients and in 1 of 18 patients, respectively. CONCLUSIONS: The most frequent clinical feature of the drug eruptions were exanthematous in nature and the most common causative drugs were antibiotics, as suspected. To search for the causative drug of the drug eruption, the only usual methods of patch and prick tests were not sufficient in our study.

Striae Distensae is a very common cosmetic problem. The effectiveness of various lasers, such as the 585-nm pulsed dye laser on the treatment of striae distensae has recently been reported. However, the potential pigmentary alteration of dark skin by pulsed dye laser is known. Thermage is a radiofrequency capable of delivering higher energy fluences to a greater volume of tissue than nonablative lasers, with no epidermal injury. We report three patients who had striae distensae. They were treated with Thermage and 585-nm pulsed dye laser. The treatment was effective and safe for dark skin.

Intense pulsed light (IPL) Quantum SR(TM) systems are high-intensity light sources, which emit polychromatic light. Unlike laser systems, these flashlamps work with noncoherent light in a broad wavelength spectrum of 560-1200 nm. IPL Quantum SR(TM) has been effective for the treatment of photoaging skin as a nonablative method. Three patients with photoaged skin were treated with fifth full-face treatments at 3-4 week intervals using IPL Quantum SR(TM). The cut-off filters of 560 nm and integrated contact cooling system were utilized for treatments. After the last treatments, the patients showed the overall improvement in clinical appearance, reduction in pigmentation and telangiectasia and fine wrinkle with smoothening of skin textures. Histological evaluations showed new collagen production after treatment. Full-face photorejuvenation using IPL Quantum SR(TM) can be an effective treatment modality for photoaged skin. We report herein IPL photorejuvenation is safe and effective in skin rejuvenation.

Thyroid hormone plays an important role in the process of implantation of a fertilized egg in the endometrium, as well as in the division and development of the fertilized egg. In addition, maternal thyroid hormone is essential for the formation and development of the fetal brain, nervous system, and bones. Therefore, when maternal thyroid hormone is insufficient, complications such as miscarriage, stillbirth, low birth weight and preeclampsia increase. Guidelines for the diagnosis and treatment of thyroid dysfunction during pregnancy were established and published by the American Endocrine Society, the American Thyroid Association, and the European Thyroid Society. The Korean Thyroid Society also published recommendations for diagnosis and treatment of thyroid disease during pregnancy and postpartum in 2014. However, since the revised guidelines of the American Thyroid Association were published in 2017, many studies, including large-scale randomized controlled trials, have been published in relation to thyroid and pregnancy, and the need to revise the existing recommendations has emerged in Korea.The main revisions of this recommendation are changes in the normal range of TSH during pregnancy, detailed description of treatment policies according to pregnant women’s autoantibodies and thyroid function status. Also, a description of the effect of thyroid autoantibodies on assisted reproductive procedures has been added.

Differentiated thyroid cancer demonstrates a wide range of clinical presentations, from very indolent cases to those with an aggressive prognosis. Therefore, diagnosing and treating each cancer appropriately based on its risk status is important. The Korean Thyroid Association (KTA) has provided and amended the clinical guidelines for thyroid cancer management since 2007. The main changes in this revised 2024 guideline include 1) individualization of surgical extent according to pathological tests and clinical findings, 2) application of active surveillance in low-risk papillary thyroid microcarcinoma, 3) indications for minimally invasive surgery, 4) adoption of World Health Organization pathological diagnostic criteria and definition of terminology in Korean, 5) update on literature evidence of recurrence risk for initial risk stratification, 6) addition of the role of molecular testing, 7) addition of definition of initial risk stratification and targeting thyroid stimulating hormone (TSH) concentrations according to ongoing risk stratification (ORS), 8) addition of treatment of perioperative hypoparathyroidism, 9) update on systemic chemotherapy, and 10) addition of treatment for pediatric patients with thyroid cancer.
