Oral myiasis in a child by the reindeer warble fly larva Hypoderma tarandi.

We describe a case of human oral myiasis by a first-stage larva of the reindeer warble fly, Hypoderma (Oedemagena) tarandi (L.) (Diptera: Oestridae), in a 12-year-old girl. In September the patient complained of erythema, swelling and conjunctivitis of the right eyelid. Symptoms subsided spontaneously but re-occurred in October. In December she presented with acute swelling of the right corner of the mouth. Later that day a living larva protruded from this swelling. The patient had been on vacation in Norway during the previous summer months.
