Atypical neonatal cutaneous myiasis: A diagnostic challenge mimicking pustular rash in a resource-limited setting

Neonatal cutaneous myiasis is a rare disease in newborns. Although it is unlikely, the level of suspicion for this condition should be high, especially in tropical regions. Treatment may deviate from the standard approach when necessary, and chemical debridement can be considered, particularly for smaller lesions. Ultimately, clinical judgment plays a key role in decision-making.

Myiasis is the infestation of the skin of a mammal by larvae or maggots. The skin is the most affected organ. However, it can also affect other organs of the body. Gasterophilus and Hypoderma are two flies that produce creeping myiasis, a type of cutaneous myiasis our patient had. The infestation is common in Sub-Saharan Africa and most especially among rural dwellers. We report on a case of a 7-day-old term neonate who reported to St. Mary's Hospital Lacor, a Private-not-for-Profit hospital situated in the Northern region of Uganda, who was admitted as a case of neonatal sepsis with a focus on the skin initially, however, while on the ward was eventually diagnosed with Cutaneous Myiasis. The management plan included chemical debridement with Hydrogen peroxide, IV antibiotics, and other supportive therapies, and the neonate was ultimately discharged home after 9 days in the NICU. This case report aims to inform healthcare workers of the importance of heightening the index of suspicion of myiasis for neonates who present with sudden-onset rash that can resemble pustules and be mistaken for a pustular rash. Additionally, chemical debridement, in this case, underscores the importance of an innovative approach to managing cutaneous myiasis in resource-limited settings. Mass education and awareness programs focusing on proper hygiene practices, safe handling of newborns, and early recognition of symptoms can help mitigate the risk of myiasis.
