[Diagnostic atypique d'une myiase]. / Atypical diagnosis of myiasis.

Muscoid larvae were observed on self-medicated dressing material loaded with purulent material taken from a 91-year-old hospital patient. These larvae were identified as Lucilia sericata. However, no larvae were found in the patient's tissues. The observation of larvae on dressings should not automatically lead to a diagnosis of cutaneous myiasis.
