Creepy Dreadful Wonderful Parasites Case

Differential diagnosis
  • Auchmeromyia (Congo floor maggot): doesn't form furuncles (boil-like lesions with a live dipteran maggot within) but stays on the host only for feeding, similar to a bedbug; it has 3 spiracular slits per side, straight, lying horizontally
  • Cordylobia rodhani (Lund fly): has 3 posterior spiracular slits on each side but its slits are more sinuous than Cordylobia anthropophaga
