title: Human botfly infestation presenting as peri-auricular mass.
abstract: To report a new cause of peri-auricular mass in children: cutaneous myiasis-botfly infestation. Case report. The human botfly (Dermatobia hominis) is found in the tropics of Central and South America. However, cases of infestation are uncommon in the United States. We present the case of a 5-year-old girl with cutaneous myiasis in order to expand the differential diagnosis for a peri-auricular mass in children. In our report, the parasite was initially identified as sparganum, but was later reclassified by the center for disease control and prevention (CDC) as a botfly larva. Parasitic infection should be considered with a newly noted head and neck mass, and cutaneous myiasis should be included in the differential diagnosis. Cutaneous myiasis has not been previously reported in the literature describing the peri-auricular region as the site of occurrence. Furthermore, when an unusual parasite is extracted from a lesion, it should be confirmed by an authority such as CDC for definitive diagnosis, so appropriate plan of care and follow up can be instituted.
