Wound myiasis by housefly in a patient with pemphigus vulgaris in Riyadh, Saudi Arabia

Myiasis is the infestation of live vertebrates by dipterous larvae. Cutaneous myiasis is the most common form, although many organs can be infected by these larvae. Cutaneous myiasis is divided into 3 forms: localized furuncular, migratory, and wound myiasis, which have a worldwide distribution, but tropical and subtropical countries have a heavier burden of the disease. Herein, we report a case of scalp wound myiasis in a patient with pemphigus vulgaris caused by Muscidae domestica (M. domestica) in Riyadh, Saudi Arabia. Cases of M. domestica myiasis are limited in the literature. We would like to raise awareness regarding the possibility of cutaneous myiasis in M. domestica in Riyadh, Saudi Arabia.
