Botfly myiasis after travel to Bolivia.

Following a trip to Bolivia, a 32-year-old woman developed a left lower leg ulcer with a sensation of movement within the lesion. After being seen by four primary care providers, she was referred to dermatology 7 weeks after her return from Bolivia. At that time, she was found to have a 5 mm weeping ulcer, with a live larva visible at the base. We conducted a punch biopsy for botfly removal, after which the patient healed well. Herein we discuss the ways in which clinical presentation, history of travel, dermoscopy, and ultrasound can contribute to diagnosing botfly myiasis. While treatment of botfly infestation is not required, we discuss the importance of shared decision-making in considering treatment, as well as methods for extraction, including mechanical or surgical removal, which may help to reduce patient anxiety and the risk for secondary infection. As global travel resumes to levels prior to the Covid-19 pandemic, it is important for dermatologists to be aware of the presenting symptoms and treatment of tropical skin disorders.
