Gingival Myiasis on Oral Squamous Cell Carcinoma in Turkey: A Case Report

Myiasis is a disease caused by tissue invasion of diptera larvae and eggs. Oral myiasis is mostly related to old age, poor oral hygiene, suppurative lesions, anatomical disorders and cancer cases. Oral squamous cell carcinoma (OSCC) is an important risk factor for myiasis. This report presents the case of an 82-year-old woman who presented with gingival myiasis developing on the background of OSSC. The patient was diagnosed with OSSC in the hospital. Myiasis larvae were identified and sent to the National Parasitology Reference Laboratory for identification. Thus, development of myiasis on OSCC background was shown in Turkey for the first time. Myiasis larvae have been identified as the 3rd phase of the larvae Sarcophaga sp. development (Diptera: Sarcophagidae). As a result, myiasis cases are sporadic in Turkey, and it can be avoided by controlling fly population and by paying attention to hygiene. Controlling myiasis is an important public health problem and should be considered in a single health concept, as it causes health problems in both humans and animals. The findings of this case will draw attention to the importance of dealing with myiasis factors, which is a public health problem.
