Insights
Infantile acne, specifically nodulocystic acne in a 20-month-old girl, may require oral isotretinoin when antibiotics fail. This treatment effectively cleared severe acne, demonstrating its utility in pediatric cases.
Area of Science:
- Pediatric Dermatology
- Dermatology
- Clinical Case Study
Background:
- Infantile acne typically presents between 6-16 months, with a male predominance.
- Severe nodulocystic acne in infants can be challenging to treat with conventional therapies.
- Endocrinopathy is usually absent in infantile acne cases.
Observation:
- A 20-month-old female presented with nodulocystic acne unresponsive to oral antibiotics.
- No clinical or biological signs of endocrinopathy were observed.
- Treatment with oral isotretinoin was initiated due to the severity and lack of response to antibiotics.
Findings:
- A seven-month course of oral isotretinoin achieved complete remission of nodulocystic acne.
- The patient exhibited good clinical and biological tolerance to isotretinoin, with no growth retardation.
- Relapse of lesions occurred after treatment cessation but was less severe and manageable with topical therapies.
Implications:
- Oral isotretinoin is a viable and effective treatment option for severe infantile nodulocystic acne unresponsive to antibiotics.
- Early intervention with isotretinoin can potentially reduce the risk of scarring in pediatric acne patients.
- Pediatric dermatologists should consider isotretinoin for recalcitrant infantile acne cases, monitoring for tolerance and potential relapse.
Abstract:
We report the case of a little girl who presented with a nodulocystic acne which had its onset at the age of 20 months. She had no clinical or biological features of endocrinopathy. The lesions did not respond to conventional antibiotics so she was started on oral isotretinoin. A seven-month treatment period was necessary to achieve remission. The onset of infantile acne is usually around 6 to 16 months and there is a male predominance. The onset is later in females. Oral erythromycin is the first line treatment when topical therapies are inefficacious. Some cystic lesions do not respond to oral antibiotics. In these cases, oral isotretinoin may be effective and the treatment is similar to that of an adult. Clinical and biological tolerance is good with no growth retardation. Lesions may relapse after the withdrawal of isotretinoin but they are less important and easily controlled with topical treatments. Isotretinoin can be used for nodulocystic acne to reduce the risk of scarring.
