Breast myiasis in an elderly male patient: a case report

Fly larvae cause myiasis. The most common of these are Cordylobia anthropophaga and Dermatobia hominis. Clinically, myiasis manifests as an erythematous papule that may become ulcerated and form furuncular lesions. In patients who have been in endemic areas, these larvae are to be suspected. Below, we present a 75-year-old male with a clinical picture of a palpable mass in the areola associated with the outflow of serohematic fluid through a central orifice. A breast intraductal lesion was suspected, so a breast ultrasound and biopsy were performed, which showed a structure compatible with myiasis. The diagnostic challenge was the high number of different diagnoses and the little knowledge of health professionals about tropical diseases.
