Cutaneous myiasis in a geriatric patient

Area of Science:

• Medical Entomology
• Clinical Case Study

Background:

• Cutaneous myiasis is infrequently documented in Italy, particularly involving endemic fly species.
• Human cases of myiasis are often associated with poor hygiene and pre-existing wounds.

Observation:

• A case of severe cutaneous myiasis was observed in a woman presenting with infected, ulcerated foot lesions extending to the knee.
• The patient was in a precarious state of hygiene upon admission to the Emergency Department.

Findings:

• Fly larvae, identified as Lucilia sericata (Meigen, 1826), were discovered within the patient's foot lesions.
• Larval infestation was confirmed as the cause of the extensive inflammation and ulceration.

Implications:

• This case highlights the importance of recognizing and managing cutaneous myiasis, even in regions where it is uncommon.
• Prompt diagnosis and appropriate treatment, including antibiotic therapy and wound care, are crucial for patient recovery.
• Further surveillance of endemic fly species and their potential to cause myiasis in humans is warranted.
