Background: Although patients with malignant melanoma in situ (MIS) have a high survival rate, a risk of recurrence or upstaging remains. Thus, a comprehensive understanding of its prognosis is essential for optimal patient management. Objective: To investigate the clinical characteristics and survival outcomes of Korean patients with MIS. Methods: We retrospectively analyzed the medical records and photographs of patients with MIS treated at a single tertiary center between 2008 and 2021. Clinical features, including diagnosis, treatment, recurrence, and mortality, were examined. Results: A total of 156 patients with MIS were included, with a mean age of 59.3 years. The most common subtype was acral lentiginous melanoma (80.8%). Delayed diagnosis was associated with subungual MIS (SUMis; p ＜0.05). Among the subtypes other than SUMis, 77.3% met three or more of the ABCD criteria for melanoma.Hutchinson’s sign was observed in 67.3% of cases of SUMis. Ulceration was present in only two cases (1.3%).Recurrence occurred in nine patients (5.8%), with four (2.6%) experiencing relapse after 5 years. Upstaging was observed in two patients (1.3%) due to intralymphatic or regional nodal metastasis occurring at 19 and 10 months post-treatment. The 5-year and 10-year melanoma-specific/overall survival rates were 100.0/96.9% and 100.0/89.0%, respectively. Conclusion Although the survival rates of patients with MIS are high, long-term and close follow-up after treatment is essential because of the possibility of late recurrence and rare instances of intralymphatic or regional nodal metastasis. Additionally, the presence of clinical ulceration is highly suggestive of invasive melanoma.

Meningiomas are common intracranial tumors; however, reports on extracranial cutaneous meningiomas are exceedingly rare. A 77-year-old woman visited our hospital with an asymptomatic child fist-sized mass on the scalp.Biopsy results indicated nuclear atypia and mitoses of sarcomatous cells. Brain magnetic resonance imaging revealed a subgaleal mass with strong enhancement. Suspecting sarcoma, wide excision was performed jointly by the departments of plastic surgery and neurosurgery, during which no evidence of cranial invasion was noted. In the surgical specimen, numerous mitoses of sarcomatous cells and poorly formed nests of epithelioid cells were observed. This led to the diagnosis of anaplastic meningioma without intracranial origin. Subsequently, the patient received adjuvant radiotherapy and is currently under close follow-up. Anaplastic meningioma is rare, but early diagnosis is important as it enables timely and appropriate treatment, thus, improving survival rates. Dermatologists should remain vigilant as meningiomas can manifest as cutaneous scalp nodules, and their accurate diagnosis can profoundly impact prognosis.

A 54-year-old man presented to our outpatient clinic with generalized pruritic millet-sized vesicles, pustules, and crusts on the whole body over the past 10 years, which were more dominant in the lower extremities. Due to the difficulty in diagnosis, a series of histopathologic examinations were conducted during the treatment course, and the findings were similar: subcorneal pustules with neutrophils, superficial perivascular and dermal infiltration of lymphocytes, neutrophils, and eosinophils, with no sign of acantholysis. The patient was treated with cyclosporine, prednisolone, doxycycline, colchicine, sulfasalazine, and acitretin; however, his condition did not improve. After showing a dramatic improvement with dapsone, he was finally diagnosed with subcorneal pustular dermatosis (SPD).Various medications commonly used in inflammatory and immunobullous skin diseases were tried but failed to improve the condition; the patient showed a dramatic response only to dapsone. Due to its rarity, careful attention and repeated biopsies are required for diagnosing SPD.

Methotrexate (MTX) is commonly employed in the management of chronic inflammatory skin diseases. We report the case of a 73-year-old man who presented with a persistent cough lasting for 1 month. He had an 11-year history of psoriasis and had received MTX (10.0 mg/wk) over the past 21 months. High-resolution chest computed tomography revealed diffuse ground-glass opacities and bronchiectasis affecting both lung fields. Based on clinical and radiological assessments, the patient was diagnosed with MTX-induced interstitial pneumonia. Notably, significant clinical and radiological improvement was observed 1 month after the discontinuation of MTX and corticosteroid administration. Although some reports have demonstrated lung toxicity in patients receiving high-dose MTX therapy, cases of adverse pulmonary effects following low-dose treatment in patients with psoriasis are rare.This case report underscores the rarity of interstitial pneumonia in a patient with psoriasis undergoing MTX treatment in Korea.

The Department of Dermatology at Kyungpook National University School of Medicine, initially the Dermatology Department of the Private Daegu Medical Training School in 1924, commemorated its 100th anniversary in 2023.Throughout its rich history, the department has been dedicated to advancing contemporary dermatology and enhancing the well-being of local communities through exceptional research, education, and social contributions.Initially tasked with the diagnosis, treatment, and education of patients with dermatological and urological disorders, the department evolved over time. In 1958, it separated from the Urology Department to focus solely on the diagnosis, research, and education of dermatological disorders. In 1962, Dr. Soon Bong Suh became the inaugural Chief of the Dermatology Department, marking the foundation of the Kyungpook National University School of Medicine’s Dermatology Department. Our legacy of pioneering contributions extends to dermatophytic diseases, which account for a large proportion of skin disorders in Korea, where we have excelled in basic research and treatment. These achievements have played a crucial role in the advancement of dermatophytic diseases.Subsequently, we have demonstrated expertise in blistering diseases and dermatopathology, making substantial contributions to the diagnosis and treatment of refractory skin conditions. Recently, we have been at the forefront of research and interventions for chronic inflammatory skin conditions that cause significant distress in many individuals, including atopic dermatitis and psoriasis. Our influence has also extended to severe and refractory skin disorders, including skin cancer and vascular anomalies. Striving to stay contemporary, our achievements now encompass aesthetics, including acne, pigmentation, and laser treatments. Our accomplishments have garnered widespread recognition nationwide, engendering high expectations for future advancements.

Background/Aims: The optimal systolic blood pressure (SBP) goal for elderly patients with hypertension, especially to reduce cardiovascular disease (CVD) incidence and improve outcome, is unclear. This study aimed to evaluate the beneficial effects of intensive treatment for hypertension on the incidence of CVD in elderly Korean patients. Methods: The HOW to Optimize eLDerly systolic Blood Pressure (HOWOLD-BP) trial is a multicenter, parallel-design, open-label, randomized controlled trial designed to evaluate whether intensive treatment (SBP ≤ 130 mmHg) will provide more benefits in lowering the incidence and mortality associated with CVD than standard treatment (SBP ≤ 140 mmHg) in elderly patients with hypertension aged ≥ 65 years. For this study, eleven university hospitals in Korea will enroll approximately 3,176 elderly patients with hypertension between 2019 and 2022. Patients will be requested to visit the clinic every 4 months for the first year and every 6 months thereafter for 36 months. Parameters, including clinic and home blood pressure, anthropometric and laboratory findings, and frailty assessments, will be collected according to the standardized protocol. The primary outcome is a composite of CVD (acute coronary syndrome, stroke, and heart failure) incidence and cardiovascular deaths. Results: As of December 2021, 1,655 participants had been enrolled in the study, including 831 patients in the standard group and 824 patients in the intensive group. Conclusions The HOWOLD-BP trial is the first study performed in Korea to evaluate the beneficial effects of intensive blood pressure treatment on CVD in elderly patients with hypertension. The results of this study will help clarify the appropriate target SBP for this population.

BACKGROUND: Secukinumab, a fully human monoclonal antibody that targets interleukin (IL)-17A, which is a central cytokine in the pathogenesis of psoriasis, has emerged as a promising treatment for moderate to severe psoriasis. However, to date, there are no real-world data for secukinumab in Korean patients with psoriasis. OBJECTIVE: To assess the clinical efficacy and safety of secukinumab in Korean patients with psoriasis. METHODS: Prospective data were gathered during follow-up from 28 consecutive patients with chronic plaque-type psoriasis treated with secukinumab for minimum of 12 weeks at a single referral center. Patient demographics, Psoriasis Area Severity Index (PASI) score, Physicians' Global Assessment (PGA), Dermatologic Life Quality Index (DLQI), and adverse events were investigated. RESULTS: The mean PASI score was significantly decreased after the induction period of secukinumab treatment (paired t-test, p<0.05). Of the 28 patients, 17 (60.7%) had obtained near complete clearance (PASI 90) at the last follow-up visit. No unexpected adverse events, other than nasopharyngitis, were observed. CONCLUSION: Secukinumab can be of benefit for the treatment of Korean patients with psoriasis, as the treatment was associated with a rapid and satisfactory response and safety profile.
