RESUMO

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.

RESUMO

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.

RESUMO

Background@#Although particulate matter likely provokes inflammatory reactions in those with chronic skin disorders like atopic dermatitis, no study has examined the relationship between particulate matter and psoriasis exacerbation. @*Objective@#This study evaluated possible associations between particulate matter and hospital visits for psoriasis patients in 7 major cities in South Korea. @*Methods@#We investigated the relationship between psoriasis and particulate matter. To do this, we used psoriasis patient data from the Korean National Health Insurance Service database. In addition, PM 10 and PM 2.5 concentration data spanning a 3-year time frame were obtained from the Korea Environment Corporation. @*Results@#A pattern analysis generated by the sample cross-correlation function and time series regression showed a correlation between particulate matter concentration and the number of hospital visits by psoriasis patients. However, the prewhitening method, which minimizes the effects of other variables besides particulate matter, revealed no correlation between the two. @*Conclusion@#This study suggests that particulate matter has no impact on hospital visit frequency among psoriasis patients in South Korean urban areas.

RESUMO

An 83-year-old man presented with an intermittently bleeding fixed nodule on the left side of the chest for 2 months. Due to the clinical suspicion of metastatic cancer or a ruptured epidermal cyst, a punch biopsy was performed, which revealed granulation tissue. During surgical excision, a connection between the granulation tissue and the deeper structure was confirmed. Based on the clinicopathological findings, a cutaneous fistula was suspected;a detailed history revealed that he had experienced blunt chest trauma in a motorcycle accident 2 months before. Subsequent chest computed tomography showed soft tissue infiltration in the left sixth rib. Finally, the patient was diagnosed with a cutaneous fistula and underwent resection of the left sixth rib and costal cartilage. Cutaneous fistulae rarely occur in the chest. In cases where a recalcitrant inflammatory nodule is observed on the chest, the patient’s trauma history and ordinary medical history should be evaluated to rule out a cutaneous fistula.

RESUMO

Background@#Psoriasis is a chronic disease that can have accompanying comorbidities including arthritis, metabolic syndrome, and cardiovascular diseases. Patients with psoriasis tend to frequently visit medical institutions, and their economic burden for medical services is high. @*Objective@#To investigate the economic burden of psoriasis in Korea. @*Methods@#The Korean Society for Psoriasis conducted a multi-center field survey of the patients and analyzed the national insurance claim data. Also, we discussed the medical environment of psoriasis in Korea based on the results. @*Results@#The economic burden of psoriasis patients is substantial and varied by the type of medical institute. Patients also paid the indirect and intangible medical costs. Biological agents, which is used in patients with severe psoriasis, led to an increase in the cost. @*Conclusion@#This is the first study to estimate the economic burden of psoriasis in Korea comprehensively. To improve the medical environment of psoriasis and alleviate the burden of patients, discussion on the more efficient health policy and medical insurance criteria for psoriasis would be needed.

RESUMO

Background@#Only a few studies have tried to assess factors relevant to the satisfaction of the participants in atopic dermatitis (AD) educational programs. More systematic modeling of this issue is needed. @*Objective@#To examine the benefit of a conjoint educational program for AD on patients and caregivers in a clinical setting. @*Methods@#In a half-day educational program called “AD school”, 831 people (493 patients and 338 family members) participated for 8 years. Various educational and entertaining programs were provided. The on-site survey was administered to measure participants’ satisfaction and perception of the benefit. We applied structural equation modeling to identify the relations among satisfaction and perception. @*Results@#A total of 209 family survey data was obtained and analyzed. The survey items were grouped into four categories. The categories were classified as individual education, group education, fun activity, and overall satisfaction (fun, benefit, intention to re-join and recommend to others). According to the model that we built, comprehensive group education was demonstrated to be the most relevant factor affecting overall satisfaction. @*Conclusion@#Our holistic approach would allow dermatologists to improve the efficacy of the conjoint educational program for AD.

RESUMO

Nevus comedonicus is a very rare skin disorder characterized by the presence of comedo-like dilated pores with keratinous plugs, rarely resulting in painful recurrent inflammatory nodules or cysts. It presents as localized or extensive form. It displays unilaterally or bilaterally segmental distribution. Histopathologically, it is characterized by keratin-filled epidermal invagination with bulbous proliferation of keratinocytes. The condition may be caused by fibroblast growth factor receptor 2 mutation. Although it may be controlled by a variety of therapeutic modalities, it is difficult to achieve complete resolution. We report a case of extensive nevus comedonicus with inflammatory nodules and cysts controlled with adalimumab.

RESUMO

Background@#Cutaneous malignant melanoma (CMM) develops mainly in the elderly, although it is often seen in young patients and in clinical practice. However, there are few studies on the clinical features of young patients with CMM in Korea. @*Objective@#To investigate the clinical characteristics of young Korean patients with CMM. @*Methods@#We retrospectively reviewed the medical records of patients with CMM between January 2009 and June 2019 and compared the clinical features of CMM in patients aged 10∼39 and 50∼79 years. @*Results@#Of the 341 patients with CMM, only 22 (6.5%) were between the age of 10∼39 and 250 (73.3%) were aged 50∼79. Acral lentiginous melanoma (ALM) was the most common clinical subtype in both groups (45.5% and 71.2%, respectively). Subungual melanoma was more common in age 10∼39 years (27.3% vs. 17.2%), whereas ALM except subungual melanoma was more common in age 50∼79 years (18.2% vs. 54.0%). Superficial spreading melanoma (31.8%) was also a significant subtype observed in age 10∼39 years (p<0.001). Frequently involved locations in age group 10∼39 were fingers (27.3%) and trunk (22.7%), but feet (40.8%) were common in age group 50∼79 (p=0.009). There were no differences in mean Breslow thickness, lymph node metastases, or staging of CMM (p>0.05). @*Conclusion@#Compared with elderly patients, CMM in patients aged 10∼39 showed differences in the location of the lesion and clinical subtype. Therefore, a misdiagnosis can be prevented when a young patient has suspected CMM on the finger or trunk.

RESUMO

Cytophagic histiocytic panniculitis (CHP) is a rare form of panniculitis, presenting lymphohistiocytic infiltration within subcutaneous fat tissue with phagocytic histiocytes. Associated systemic symptoms includes fever, hepatosplenomegaly, lymphadenopathy, serositis, pancytopenia, hepatic abnormalities, hypertriglyceridemia, and coagulopathy, which are the features of hemophagocytic lymphohistiocytosis (HLH). The patients of CHP associated with HLH may have nonfatal acute/intermittent, or rapidly fatal clinical courses, so the prompt and accurate diagnosis with immunosuppressive treatments are significant.

RESUMO

BACKGROUND: Tinea capitis is a cutaneous infection of dermatophytes and predominant in children. Although tinea capitis in Korea is controlled by oral antifungal medications and concerted public health initiatives, it's still a health issue.OBJECTIVE: To investigate changes in the epidemiological and mycological characteristics of adult patients with tinea capitis in southeastern Korea.METHODS: Using medical records from Kyungpook National University Hospital and Catholic Skin Clinic from 1989 to 2018, we retrospectively investigated the epidemiological and mycological characteristics of 266 adult patients (aged over 20) with tinea capitis.RESULTS: Among total 266 patients, 239 were KOH-positive. The annual incidence of tinea capitis ranged from 3 to 18 between 1989 and 2018. Of the total, 54 (20.30%) were male and 212 (79.70%) were female. Eighty patients (30.08%) were in their seventies, the most commonly affected age group. Of the remaining, 58 (21.80%) were in their sixties, and 41 (15.41%) in eighties. Among all, 77 (28.95%) visited the hospital in summer, 72 (27.07%) in spring, 64 (24.06%) in winter, and 53 (19.92%) in fall. Dermatophytes were cultured from 171 patients. Microsporum canis was the most common dermatophyte (42.48%), while Trichophyton rubrum was the second (15.79%). Of the 266 patients, 186 (69.92%) lived in urban areas and 80 (30.08%) in rural areas.CONCLUSION: The epidemiological and mycological characteristics of adult patients with tinea capitis were different from those of children in terms of annual incidence, sex distribution, and isolated dermatophytes. These results provide useful information for the treatment and prevention of tinea capitis.

RESUMO

Exenatide extended-release was recently developed as an antidiabetic drug; it acts as a glucagon-like peptide-1 receptor agonist. A 54-year-old male visited our clinic complaining of a subcutaneous tender nodule on his left thigh that had developed over the course of 1 week. The patient had received exenatide extended-release injections for 5 months to treat diabetes. A histopathologic examination showed septal and lobular panniculitis with lymphohistiocyte and eosinophil infiltration. The patient was diagnosed with eosinophilic panniculitis (EP) due to exenatide extended- release injection. EP is a rare type of panniculitis characterized by a prominent infiltrate of eosinophils in the subcutaneous fat layer. It is a histologic reaction pattern that is associated with various clinical conditions. Among the injection- site reactions reported in exenatide extended-release users, injection-site nodules occur infrequently. Clinicians who treat diabetics who use exenatide extended-release should be aware of the possible occurrence of injection-site nodules.

RESUMO

Anagen effluvium is an abrupt loss of hair in its growing phase due to an event that impairs the mitotic or metabolic activity of the hair follicle. Anagen effluvium is commonly associated with the administration of chemotherapy, radiation, and drugs as well as exposure to toxic chemicals. However, alopecia due to the administration of anti-tuberculosis drugs has rarely been reported in the literature. A 50-year-old female was diagnosed with intestinal tuberculosis and was started on anti-tuberculosis therapy with isoniazid, rifampicin, ethambutol, and pyrazinamide. After starting the treatment, erythematous to brown patches appeared all over her body, which was followed by diffuse hair loss on the scalp and body. Hair examination showed intact inner and outer root sheaths with fully pigmented hair bulbs, and histopathological examination of a scalp biopsy showed vacuolar degeneration in the interfollicular epidermis and perifollicular infiltration of mononuclear cells and eosinophils. The condition was diagnosed as anagen effluvium with drug eruption, and a potent corticosteroid lotion was prescribed for scalp application twice a day. After complete hair loss, the anti-tuberculosis medications were withdrawn, and hair regrowth started 4 months later. Here, we report a rare case of anagen effluvium with generalized drug eruption due to anti-tuberculosis medication.

RESUMO

BACKGROUND@#Tinea capitis is a contagious fungal infection that occurs predominantly in childhood. Although its incidence has declined, its epidemiological and mycological characteristics are continue to evolve.@*OBJECTIVE@#To assess changes in the epidemiological and mycological characteristics of tinea capitis in teenage patients in Southeastern Korea.@*METHODS@#We retrospectively investigated epidemiological and mycological characteristics of 202 teenage patients with tinea capitis who visited Kyungpook National University Hospital and the Catholic Skin Disease Clinic from 1989–2018.@*RESULTS@#Of 202 patients, 177 patients showed KOH-positivity. Dermatophytes were cultured from 157 patients. The annual incidence of tinea capitis ranged from 0 to 30 between 1989 and 2018. Of 202 patients, 153 patients (75.74%) were male and 49 patients (24.26%) were female. The ratio of male to female was 1:0.32. For seasonal distribution, 78 patients (38.61%) visited our hospital in winter, 59 patients (29.21%) visited in spring, 35 patients (17.33%) visited in fall, and 30 patients (14.85%) visited in summer. Microsporum canis was the most common dermatophyte (44.06%) isolated from tinea capitis. Trichophyton tonsurans was the second most common dermatophyte (26.73%). For inhabitancy distribution, 151 patients (74.75%) lived in urban areas and 51 (25.25%) lived in rural areas.@*CONCLUSION@#The epidemiological characteristics of teenage patients with tinea capitis were distinct from those of adults in annual incidence, sexual distribution and isolated dermatophytes. Trichophyton tonsurans was the main causative organism of tinea capitis in recent 10 years. These results are useful for the targeted treatment and prevention of tinea capitis.

RESUMO

Cutaneous lesions of leukemia cutis (LC) by chronic neutrophilic leukemia (CNL) have been merely reported due to the rare occurrences of CNL. Furthermore cutaneous lesions in relation to clinical severity have been far less studied. A 70-year-old man presented with multiple violaceous papules and excoriations on both lower extremities. The diagnosis was LC based on histologic and laboratory evaluation and the origin was elaborated as CNL with the confirmation of colony stimulating factor 3 receptor (CSF3R) mutation. Interestingly, the patient presented clinical severity in a parallel manner to the hematologic abnormality. To the best of our knowledge, there has been no reported case of CSF3R confirmed LC in CNL featuring explicit skin eruption in relation to laboratory findings.

RESUMO

BACKGROUND: Alopecia areata (AA), a chronic, relapsing hair-loss disorder, is considered to be a T-cell-mediated autoimmune disease. Cold-inducible RNA-binding protein (CIRP) belongs to a family of cold-shock proteins that respond to cold stress, and has been identified as a damage-associated molecular pattern (DAMP) molecule that triggers the inflammatory response. Recent studies have shown that high-mobility group box 1, another DAMP molecule, is elevated in serum and scalp tissue of AA patients, suggesting a relationship between DAMP molecules and the pathogenesis of AA. OBJECTIVE: To investigate the clinical significance of serum CIRP levels in AA. METHODS: The serum levels of CIRP were compared between 68 patients with AA and 20 healthy controls. Additionally, the correlation between CIRP level and various clinical parameters was evaluated. RESULTS: The serum CIRP levels were significantly higher in AA patients compared to healthy subjects. Moreover, there was an association between the serum CIRP level and clinical characteristics, such as disease duration and disease activity. However, there was no significant difference in the serum CIRP level among the clinical types of AA (AA multiplex, alopecia totalis, and alopecia universalis). CONCLUSION: These results suggest that CIRP may play a significant role in the pathogenesis of AA and could be a potential biologic marker for monitoring the disease activity of AA.
