Breast myiasis: Are we prepared for the correct diagnosis?

Cutaneous myiasis is an endemic infestation in Latin America and Africa. Many unusual sites of larval infection can cause diagnostic confusion, especially if the patient is not from an endemic area. In the breast, the furuncular aspect suggests some differential diagnosis. We report a case of an 84-year-old patient with an ulcerated lesion on the right breast, who was referred to the reference service to exclude malignancy. Considering the clinical aspects and after further evaluation with imaging methods, she was diagnosed with myiasis. This study reinforces the importance of differential diagnosis of myiasis in patients that come from endemic areas.
