Dermatomycosis refers to any fungal infection of the skin and may be caused by dermatophytes, yeast, or other fungi, including those that do not usually cause cutaneous disease. Clinical diagnosis of a dermatomycosis can be confirmed by microscopic detection of fungal elements, by identification of the species through culture, or by histologic evidence of the presence of fungal material in the tissue. In superficial mycoses, direct smear with KOH and fungal culture are the most valuable and useful diagnostic methods. For this reason, skin biopsy is not often employed in the workup of dermatophytosis or other superficial mycoses. But it is useful in diagnosis of deep fungal infections and some lesions in which KOH examination of scale is negative. This review article aims to provide insights on the histopathology and various special stains in diagnosing dermatomycosis.

Background: Skin diseases associated with Malassezia species include malassezia folliculitis, pityriasis versicolor, and seborrheic dermatitis. Although several treatment options are available for the treatment of pityriasis versicolor, there is a lack of research data on sulfur preparation, which is a time-honored therapeutic agent; furthermore, data comparing topical antifungal agent and sulfur preparation is not available. Objective: The purpose of this study was to compare the efficacy and usefulness of a mixture of diflucortone valerate 1 mg/g and isoconazole nitrate 10 mg/g ointment (Travocort) and sodium thiosulfate solution 25% for pityriasis versicolor. Methods: A retrospective review was performed with 185 patients diagnosed with pityriasis versicolor who presented to the Department of Dermatology, Daegu Catholic University Medical Center between August 2002 and December 2021. Results: Of the 185 patients, 82 used Travocort while 103 used sodium thiosulfate solution. The average duration of the treatment was 19.3 days for Travocort and 28.8 days for sodium thiosulfate solution (p=0.001). The success rate of the treatment after 2 weeks was 65.8% for Travocort and 56.3% for sodium thiosulfate solution. Side effects occurred in 12.1% and 4.8% of the patients in the Travocort and sodium thiosulfate solution group, respectively. Conclusion Travocort had a faster healing rate than sodium thiosulfate solution. However, topical antifungal agents can cause side effects like localized cutaneous reaction. Furthermore, the glucocorticoid portion in combination therapy may induce various side effects with long-term use. Therefore, considering the side effects of Travocort, sodium thiosulfate solution can be used as a safe alternative when long-term treatment is required.

BACKGROUND: Exposure and sensitization to fungal allergens can evoke the development and worsen allergic diseases. Many patients with allergies show multiple positive reactions to different allergens. OBJECTIVE: The purpose of this study was to analyze the relationship between fungal allergens that are mostly found in South Korea and other positive reactions to the allergens of the multiple allergosorbent simultaneous test chemiluminescent assay (MAST-CLA). METHODS: We enrolled 1,040 (588 men, 452 women) patients who showed positive reactions to three fungi, namely, Alternaria alternata, Aspergillus fumigatus, and Cladosporium herbarum, using MAST-CLA at Daegu Catholic University Medical Center from January 2010 to July 2017. The epidemiology and relationship between positive reactions to multiple fungal allergens and positive reactions to the allergens of the MAST-CLA were investigated. RESULTS: A. alternata was the most common fungal species, followed by C. herbarum and A. fumigatus (78.8% vs. 52.1% vs. 20.1%). Patients who showed positive reactions to all fungal allergens had 4.97 other antigens on average. Statistically significant results were obtained when comparing positive reactions to all fungal allergens to other allergens (Spearman correlation coefficient = 0.129, p < 0.05). CONCLUSION Patients should be educated on allergic diseases caused by other antigens if they are sensitized to fungal antigens.

BACKGROUND: Verruca plana is a common viral disease that commonly affects the face. It can autoinoculate or autotransmit, as well as cause many cosmetic problems. Skin care material that had direct contact with the skin of an affected person during a skin care procedure can be a transmission route of verruca plana or a risk factor of autoinoculation of the virus. OBJECTIVE: The goal of this study is to compare skin care behavior between skin care clinics and skin care shops, and the effects on verruca plana transmission. METHODS: Seventy-four patients who visited local dermatology clinics in Daegu from January 2011 to January 2013 were selected randomly, and a questionnaire survey was done. RESULTS: The incidence of verruca plana in patients visiting the clinic to receive skin care was higher than in the normal population. There was a statistically significant correlation between the number of procedures and the incidence of verruca plana in both skin care clinics and skin care shops. Whereas the number of verruca plana cases increased with the increase in the number of procedures in skin care shops, there was no significant correlation between the number of procedures and the incidence of verruca plana in skin care clinics. CONCLUSION: The number of procedures was significantly correlated with the incidence of verruca plana. In persons receiving treatment in skin care shops, the incidence of verruca plana increased with the increase in the number of procedures.

BACKGROUND: Bee venom (BV) has been widely investigated for potential medical uses. Recent inadvertent uses of BV based products have shown to mitigate signs of fungal infections. However, the component mediating the antifungal effect has not been identified. OBJECTIVE: This investigation compares bee venom in its whole and partial forms to evaluate the possible component responsible for the antifungal effect. METHODS: Forty-eight plates inoculated with Trichophyton rubrum were allocated into four groups. The groups were treated with raw BV (RBV), melittin, apamin and BV based mist (BBM) respectively and each group was further allocated accordingly to three different concentrations. The areas were measured every other day for 14 days to evaluate the kinetic changes of the colonies. RESULTS: The interactions of ratio differences over interval were confirmed in groups treated with RBV and BBM. In RBV, the level of differences were achieved in groups treated with 10 mg/100 µl (p=0.026) and 40 mg/100 µl (p=0.000). The mean difference of ratio in groups treated with RBV was evident in day 3 and day 5. The groups that were treated with melittin or apamin did not show any significant interaction. In BBM groups, the significant levels of ratio differences over time intervals were achieved in groups treated with 200 µl/100 µl (p=0.000) and 300 µl/100 µl (p=0.030). CONCLUSION: The the bee venom in its whole form delivered a significant level of inhibition and we concluded that the venom in separated forms are not effective. Moreover, BV based products may exert as potential antifungal therapeutics.
