title: Extensive myiasis infestation over a squamous cell carcinoma in the face. Case report.
abstract: Human myiasis is a parasitosis found in tropical and underdeveloped countries. It usually affects the elderly, unhealthy and mentally disabled individuals. It is caused by dipterous that lay their eggs in necrotic or infected tissues, although areas of the body that are apparently healthy can also be affected. Frequently the fly deposits several eggs on the peripheral parts of scratches and wounds. The treatment of myiasis involves mechanical removal of the larvae with hemostatic pincers. Larvae rupture must be avoided. Application of topical ether or similar volatile substance is useful. Preventive approach measures, including basic health care, hygiene, access to primary health service, and safe water and drainage, are fundamental to prevent human myiasis. The authors present a case report of myiasis infestation over an extensive head and neck squamous cell carcinoma from a 72-year-old patient living in a rural area. Approximately 200 larvae were removed and the patient was taken to the hospital's head and neck surgery service.
