Cutaneous myiasis is a condition caused by the infestation of the skin by larvae of certain fly species, commonly known as botflies. These larvae can enter the skin through wounds or hair follicles, leading to painful, swollen lesions. The condition is most often found in tropical and subtropical regions. Symptoms of cutaneous myiasis include itching, inflammation, and the presence of a small opening in the skin where the larvae breathe. Treatment typically involves the careful removal of the larvae, and in some cases, antibiotics may be prescribed to prevent secondary infections.
