A Survey on the Perception and Behavior Regarding Tinea Pedis among Korean Adults / 대한피부과학회지

Background@#Dermatophyte infection is one of the most common skin diseases affecting the skin, hair, and nails. Despite widespread recognition of the disease, missing details and misperceptions are commonplace in the general population. @*Objective@#This study aimed to investigate the public perception and behavior regarding dermatophytosis of the hands and feet. @*Methods@#This results from an online survey conducted between July 2022 and August 2022. The survey included 1,000 Korean participants aged 20 to 69 years, of whom 60% experienced symptoms of tinea pedis or onychomycosis. The questionnaire focused on the awareness and personal experience of tinea pedis and perception of the treatment of dermatophytosis. @*Results@#Of the 1,000 participants, nearly 80% regarded tinea pedis as a common skin condition by which anyone can be affected. Furthermore, 88.4% had heard that the treatment of tinea pedis could be harmful, causing skin rash (60.4%) and worsening liver function (48.5%). Among 896 participants who noticed suspicious symptoms, 81.2% did not visit the clinic because it was not severe (50.1%) and seemed easily manageable (25.7%). Of the respondents, 84.4% preferred to meet dermatologists rather than non-dermatologist doctors regarding skin diseases, mainly because of trust in experts and belief in a faster cure. @*Conclusion@#Providing accurate and detailed information via online media, educational campaigns, and medical papers can rectify misconceptions and improve patient appliance, contributing to public skin health.

Follicular Mycosis Fungoides Mimicking Milia / 대한피부과학회지

Follicular mycosis fungoides is a distinct variant of mycosis fungoides. Clinically, it occurs mostly in adults, affecting more males than females. It is manifested as pruritic follicular papules, acneiform lesions, or indurated plaques, typically in the head and neck. Histopathologically, it is characterized by infiltration of atypical T lymphocytes with cerebriform nuclei in the follicular epithelium (folliculotropism). We report a case of follicular mycosis fungoides manifested as a milia-like lesion combined with the patch stage of mycosis fungoides, which was treated with radiotherapy.

Lichen Planus Pigmentosus along the Blaschko's Lines / 대한피부과학회지

Lichen Planus Pigmentosus (LPP), an uncommon variant of lichen planus, is clinically characterized by insidious onset of diffuse or reticulated hyperpigmented patches on the sun-exposed areas and flexural folds. Histopathologic findings of LPP show atrophic epidermis with vacuolar degeneration of the basal cell layer and sparse lichenoid lymphohistiocytic infiltration with melanophages in the dermis. Although there have been few reports of LPP, clinical and histological pathogenesis and prognosis are not well known. Herein, we describe a case of linear LPP along the Blaschko's lines in 34-year old Korean man who presented with linear hyperpigmented, dark brown patches on his left thigh, repeatedly developing new lesions of erythematous reticular patches since puberty. This report shows the early events of LPP and the protracted course.

Serologic Evaluation in Korean Female Pattern Hair Loss Patients / 대한피부과학회지

BACKGROUND: Female pattern hair loss (FPHL) is the most common type of pattern hair loss in women. It has been suggested that FPHL is associated with several serological abnormalities. OBJECTIVE: The aim of this study is to investigate the clinical characteristics and serological abnormalities of the Korean FPHL patients and to compare them with the data from the Korea National Health and Nutrition Examination Survey V and other relative reports. METHODS: We retrospectively evaluated the age, duration and comorbidities in 264 Korean patients who have been diagnosed with FPHL. Serum levels of serum iron, total iron binding capacity, ferritin, hemoglobin, free thyroxine (T4), thyroid stimulating hormone, testosterone and 25-(OH) vitamin D were being investigated. RESULTS: FPHL was most commonly found in patients aged from 20 to 29 years old and 55% of the patients visited the hospital one year after the onset of FPHL. In FPHL patients, the levels of testosterone, hemoglobin, serum ferritin, 25-(OH) vitamin D, thyroid stimulating hormone were all significantly higher than the average Korean adult women. And, the free thyroxine level was significantly lower than the average Korean adult women. When analyzed according to the menopausal status, premenopausal FPHL patients showed significantly higher serum levels of hemoglobin, ferritin, and 25-(OH) vitamin D than those of the Korean adult women. But, the postmenopausal FPHL patients showed significantly higher serum levels of 25-(OH) vitamin D than those of Korean adult women. CONCLUSION: The levels of ferritin, testosterone and vitamin D of FPHL patients were elevated higher than those of the Korean adult women. To confirm these results in the future, further large scaled evaluation is suggested.

Inflammatory Disseminated Superficial Porokeratosis Successfully Managed by Oral Isotretinoin / 대한피부과학회지

Disseminated superficial porokeratosis is a keratinization disorder characterized by multiple brown, atrophic patches with sharply demarcated and hypertrophic ridges. Atypical cases of disseminated superficial porokeratosis with acute exacerbation accompanied by severe pruritus have been reported as "eruptive pruritic papular porokeratosis" or "inflammatory disseminated superficial porokeratosis." We report a case of inflammatory disseminated superficial porokeratosis in a 53-year-old man who was successfully treated with oral isotretinoin.

Acromegaloid Facial Appearance Syndrome with Generalized Hypertrichosis Terminalis / 대한피부과학회지

Acromegaloid facial appearance (AFA) syndrome is a rare autosomal dominant disease, consisting of an acromegaloid face, a bulbous nose, and narrowing of the palpaebral fissure. In 1996, Irvin first reported a case of a combination of acromegaloid facial appearance syndrome and congenital hypertrichosis, and reported this case as a new disease of acromegaloid facial appearance with generalized hypertrichosis terminalis, which is differentiated from both AFA syndrome and congenital hypertrichosis/gingival hyperplasia. We report herein the first Korean case of acromegaloid facial appearance with generalized hypertrichosis terminalis.

Acantholytic Squamous Cell Carcinoma on the Right Foot / 대한피부과학회지

Acantholytic squamous cell carcinoma is a well-defined, rare variant of squamous cell carcinoma in which significant portions of the neoplastic tissue show, on microscopy, a pseudoglandular or tubular pattern. It usually presents in aged patients as an erythematous nodule with scales, crust, and ulceration on sun-exposed areas. Herein we report a case of acantholytic squamous cell carcinoma that occurred on the Rt 4th toeweb of a 70-year-old man.

A Case of Cicatricial Alopecia Associated with Erlotinib

Erlotinib is a small-molecule tyrosine kinase inhibitor (TKI) of the epidermal growth factor receptor (EGFR). Erlotinib has been used primarily to treat non-small cell lung cancer. In addition to its role in tumor cells, EGFR is also an important regulator of growth and differentiation in the skin and hair. Therefore, EGFR-TKIs have been associated with a number of cutaneous side effects including follicular acneiform eruptions, cutaneous xerosis, chronic paronychia, desquamation, seborrheic dermatitis, and hair texture changes. Herein, we report a rare case of a 61-year-old woman who was treated with erlotinib and experienced cicatricial alopecia.

Circumscr ibed Palmar Hypokeratosis Treated with Cryotherapy / 대한피부과학회지

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis, and it consists of asymptomatic erythematous, well-circumscribed and depressed patch with scaly borders on the palm or sole. It usually affects middle-aged or elderly women. Histopathologically, it has a sharp stair between the normal and involved skin, and a demarcated area with an abrupt decrease in the horny layer thickness. We report herein a case of circumscribed palmar hypokeratosis that was successfully treated with cryotherapy.
