Myiasis Associated with Oral Squamous Cell Carcinoma--A Literature Review.

Advanced oral squamous cell carcinoma (SCC) is a possible risk factor for myiasis, a parasitic infestation of vital tissue of humans or other mammals by dipterous larvae (maggots). Oral myiasis is a rare entity, and is mostly associated with various medical and anatomical conditions, such as neglected mandibular fracture, lip incompetence, cerebral palsy, poor oral hygiene, suppurative lesions, and cancerous wounds. Larvae cause itching and irritation due to their crawling movements and can destroy vital tissues, inducing serious or even life-threating hemorrhage.
