DERMAL MYIASIS CAUSED BY THE FLESH FLY, PARASARCOPHAGA (LIOSARCOPHAGA) DUX (THOMSON, 1869) (DIPTERA: SARCOPHAGIDAE) AT THE SITE OF A MALIGNANT MELANOMA: A CASE REPORT.

Dermal myiasis due to the flesh fly has not been commonly reported in Thailand. A 64-year-old man came to the hospital with a 6-month history of a black tumor on the dorsum of the right great toe. The tumor was biopsied and determined to be a malignant melanoma. Second instar larvae were also seen in the wound and one larva was reared until the adult stage wherein it was identified as the flesh fly, Parasarcophaga (Liosarcophaga) dux (Thomson, 1869) (Diptera: Sarcophagidae). This case shows myiasis due to synanthropic sarcophagid flies occurs in Thailand and can occur in a malignant melanoma.
