Common misdiagnoses and prevalence of dermatological disorders at a pediatric tertiary care center

OBJECTIVES: Dermatological disorders are common in general pediatric practice. This study aimed to examine common skin problems and the manner in which they tend to be misdiagnosed. METHODS: A cross-sectional study was conducted from January 2015 to December 2016 using medical record data from the Pediatric Dermatological Outpatient Unit at Khon Kaen University, Faculty of Medicine. RESULTS: A total of 1551 visits by 769 patients were documented during the study period. A total of 114 presenting diseases were recorded. The most common skin disease in the study population was dermatitis (unspecified) (88/769, 11.4%), followed by atopic dermatitis (76/769, 9.8%) and infantile hemangioma (72/769, 9.3%). There was a total of 55 (48.2%) misdiagnosed diseases. Some unique cutaneous diseases were undiagnosed because of their rarity. However, the percentages of common cutaneous diseases, such as tinea capitis and molluscum contagiosum, which had been misdiagnosed, were also high (62.50% [95% confidence interval = 24.49–91.48] and 71.43% [95% confidence interval = 29.04–96.33], respectively). CONCLUSION: A large percentage of misdiagnoses of common cutaneous diseases may be due to general pediatricians being undereducated in the field of dermatology. Accurate recognition and appropriate management of these conditions should be emphasized for educating general pediatricians in the future.
