The present work reports a case of a female patient complaining of itching and painful lesions affecting the oral mucosa for 7 months. Buccal and lip mucosa showed swelling and erythema, with serpiginous tracks. The patient was diagnosed with oral larva migrans, and the lesions resolved after ivermectin administration. At 18-month follow-up, no sign of recurrence was observed. Larva migrans can represent a pitfall in oral diagnosis and a stressful condition for the patient. Oral health care providers should be aware of this and keep this disease in mind as a possible differential diagnosis in oral mucosa lesions.

Oral myiasis is a rare disease in humans associated with poor oral hygiene, suppurative oral lesions, alcoholism and senility, among other conditions. A case of oral myiasis in a 34-year-old white male with advanced periodontal disease and neurologic deficit is reported. Treatment consisted of manual removal of the larvae, one by one, with the help of clinical forceps and subsequent management of the periodontal disease.

Myiasis is the invasion of living tissue of humans and other mammals by the eggs or larvae of flies of the order of Diptera. It occurs mainly in the tropic, and is associated with inadequate public and personal hygiene. Oral myiasis in humans appears to be rare. This article records a case of oral myiasis caused by larvae of Hypoderma bovis. Two different pathologic soft tissue sockets were observed in the vestibular sulcus at the level of the both deciduous laterals along the deep upper lip tissues.
