Management of Myiasis in Breast Tissue

Indications for Antibiotic Use

• The Infectious Diseases Society of America recommends antibiotic therapy for immunocompromised patients with myiasis, where the risk of bacterial superinfection is elevated 1
• Antibiotics should be prescribed for patients with failed initial extraction requiring surgical debridement of necrotic tissue, as recommended by the Infectious Diseases Society of America 2

Antibiotic Selection and Duration

• The Infectious Diseases Society of America recommends first-line oral options, including Cephalexin, dicloxacillin, or clindamycin, for empirical coverage of Staphylococcus aureus and Streptococcus species in cases of secondary bacterial infection 1
• For suspected MRSA, the Infectious Diseases Society of America suggests alternatives such as TMP-SMX, doxycycline, or clindamycin, with treatment duration of 7-10 days for uncomplicated secondary infection 1, 2

Diagnostic Considerations

• The European Society for Medical Oncology advises that myiasis mimicking inflammatory breast cancer must be distinguished from malignancy, and recommends core needle or skin punch biopsy to exclude cancer in patients with a history of "mastitis not responding to at least 1 week of antibiotics" 3, 4
