8 Cases Report And Literature Review Of Facial Tinea Incognito

Objective: To make a comprehensive and systematic understanding of facial tinea incognito,so that clinical workers and non-medical staff have a further understanding of it,and strengthen the prevention to reduce the misdiagnosis and mistreatment of the disease.Methods: from July 2018 to July 2019,we collected the cases of superficial facial fungal infection that were diagnosed in the dermatology department of the Fourth Hospital of Hebei Medical University or misdiagnosed in other hospitals,for retrospective analysis and summary and literature review.Results: a total of 8 cases were collected,the ratio of male to female was 1:1,the age ranged from 3 months to 65 years,and the course of disease ranged from 5 days to 4 years.One case was misdiagnosed as worm bite dermatitis,six cases were misdiagnosed as dermatitis and eczema diseases,and one case showed herpes simplex lesions.Among them,2 had animal contact history,2 had diabetes,1 had malignant tumor,1 had fungal infection in other parts,and 1 had business trip.50% had a history of topical use of glucocorticoids,The results were all improved first and then worsened.Conclusions: The majority of misdiagnosed cases are due to the use of glucocorticoids,which can relieve the symptoms of facial ringworm but cannot be cured;the use of other external drugs,various physical stimuli,and low immunity are related to the disease;clinically,facial ringworm Most of them have lost their typical characteristics,and they should be asked for detailed medical history.They cannot be diagnosed based on clinical experience alone,and basic fungal microscopy cannot be ignored.Especially for long-lasting dermatitis,fungal infections are eliminated first to reduce misdiagnosis and missed diagnosis;non-prescription use of topical hormones should be strictly controlled to reduce abuse.
