RÉSUMÉ
Erosive adenomatosis of the nipple (EAN) is a rare benign entity that involves abnormal proliferation of the lactiferous ducts of the nipple and often presents with visible erosive lesions, erythema, or discharge. A 34-year-old female patient visited our clinic with erythematous patches and bloody discharge from the right nipple.Ultrasonography revealed a hypervascular lesion. A punch biopsy was performed, and histopathological examination confirmed the diagnosis of EAN. A 22-year-old female patient presented with a 4-year history of itchy erythematous eczematous patches with telangiectasia, crust, and bloody discharge in the areolar region. The punch biopsy results were consistent with those of EAN. The patient underwent total excision surgery. Herein, we report cases of EAN, which were difficult to differentiate from Paget's disease or nipple eczema, highlighting the need for clinicians to pay close attention.

Background@#Atopic dermatitis (AD) is a common skin disease which, depending on its severity, can have a significant impact on the quality of life of affected individuals. In cases of severe AD, systemic immunomodulatory agents can be considered for treatment. However, the available treatment options for moderate AD are limited. According to previous reports, however, 308-nm excimer light is a potential treatment for localized, moderate AD. @*Objective@#This study aimed to assess the clinical efficacy and safety of 308-nm excimer light in Korean adults with AD. @*Methods@#This study included Korean patients aged over 19 years, who were diagnosed with AD by a dermatologist, with bilateral, symmetric, and eczematous lesions. The symmetrical lesions in each patient were treated as control-test pairs. Treatment with 308-nm excimer light was applied to the test lesion twice a week for 4 weeks. The severity of the eczema, trans-epidermal water loss, and epidermal capacitance were measured. @*Results@#A total of 25 participants were enrolled in the study. After the first visit, two participants withdrew, whereas the remaining 23 completed the study. There was a statistically significant improvement in AD severity in the test group than in the control group (p<0.001). Skin barrier function also improved in the test than in the control group (p<0.01). @*Conclusion@#This study provides preliminary evidence for the use of 308-nm excimer light as a treatment option to improve symptoms and skin barrier function in moderately localized AD.

Background@#The periorbital area plays an important role cosmetically. Periorbital wrinkles are attributed to long-term, repeated use of orbicularis oris muscles and UV-induced dermal collagen degeneration. Fractional microneedle radiofrequency (RF) treats scars and laxity by creating vertical channels of injury in the dermis, triggering a scarless healing cascade and neocollagenesis. @*Objective@#To evaluate the effect and safety of a novel fractional microneedle RF device on periorbital wrinkles based on several objective indicators. @*Methods@#Eleven healthy Korean patients aged 30 to 75 years with periorbital wrinkles were included in this study. Wrinkle grades were evaluated using the Fitzpatrick wrinkle assessment scale (WAS). The melanin and erythema index, transepidermal water loss (TEWL), and three parameters for elasticity were recorded. Skin biopsies were obtained in patients who consented. @*Results@#All patients exhibited wrinkle improvement in the lateral periorbital area, and two patients also showed efficacy in the lower eyelid area. There was a statistically significant decrease in WAS and a significant improvement in the melanin index of V4 and V5. TEWL also showed a considerable decline on V4 and V5, suggesting that the water content of the skin increased with repeated laser sessions. A peak increase in viscoelasticity and a decrease in retraction time following the first laser application were observed. In the histopathologic examination, the dermis had a denser collagen and elastin content. @*Conclusion@#Microneedle fractional RF resulted in statistically significant long-term clinical improvement of periorbital wrinkles and enhanced pigmentation and skin hydration.

Background@#Acne is a complex inflammatory disorder affecting the pilosebaceous follicles of the skin. In the search for effective acne treatments, patients frequently turn to various social media platforms, including Instagram.Notably, diverse occupational groups contribute to Instagram on acne treatment, showcasing significant variations depending on the specific group. @*Objective@#This study investigated the impact and accuracy of acne treatment posts on the Korean Instagram platform. @*Methods@#We systematically examined the “top posts” with the hashtag #acne treatment, and 107 posts were included for analysis. Posts were excluded if they were not Korean, had other medical conditions, or were duplicates. @*Results@#The distribution of posts and their respective proportions were as follows: dermatologists (n=12, 11.2%), non-dermatologists (n=17, 15.9%), skin care centers (n=54, 50.5%), influencers (n=22, 20.6%), and retailers (n=2, 1.9%). Notably, dermatologists’ posts demonstrated a significantly lower number of followers and likes compared to those of skin care centers or influencer (p＜0.001, each). The similar trend was observed for the assessment of total engagement power (calculated as likes×1＋comments×1). Additionally, we evaluated the treatment accuracy of each post using the DISCERN criteria. The average DISCERN score of dermatologists’ posts was significantly higher than that of skin care centers or influencers (p＜0.001). @*Conclusion@#Our findings underscore that, despite possessing a greater level of accuracy in their information, dermatologists exert comparatively less influence on the Korean Instagram platform. Considering the recent increase in medical content on Instagram and the growing interest among patients, the role of dermatologists in providing reliable and informed guidance has become increasingly important.
