Facial myiasis and canthariasis associated with systemic lupus panniculitis: a case report.

BACKGROUND

Infestation of insects can cause myiasis due to dipetran larvae and canthariasis due to coleopteran larval or adult stages.

OBJECTIVE

To report a case of facial myiasis and canthariasis in a patient known to have panniculitis due to systemic lupus erythematosus and autoimmune hemolytic anemia.

METHOD: Larval and pupal stages of insects were recovered from the face of a patient, mounted, and identified.

RESULT: Initially, the pupal stage of the common green bottle fly Lucilia sericata was extracted from the patient's face, treated, and then came back with secondary infestation caused by two species of beetles, the drugstore beetle, Stegobium paniceum, and a beetle of the genus Trogoderma.

CONCLUSION

This is the first report on facial canthariasis due to larval stages caused by two species of beetles and recovery of pupal stages of the common green bottle fly.
