Oral squamous cell carcinoma associated with myiasis


Myiasis is a general term for infection by fly larvae feeding on the host's necrotic or living tissue. Although infestation by fly larvae is much more prevalent in animals, it is a relatively frequent in occurrence. Oral myiasis is a rare pathology in humans and is associated with poor oral hygiene. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threatening haemorrhage. The treatment is a mechanical removal of the maggots one by one; however, a systemic treatment with macrolide antibiotics, have been recently used for treatment. We present a case report of a 70-year-old man indigent, alcohol-dependent with an extensive necrotic wound in mandible and fetid odour. The prevention of human myiasis is by education, but unfortunately in the developing countries some people live in low social condition, predisposing the occurrence of the infestation.
