Ilias P. Kioulos, Emmanouil Kokkas, Evangelia-Theophano Piperaki
TL;DR
A rare case of nasal myiasis caused by Oestrus ovis was reported in Greece, where the larvae developed into pupae inside a human host.
Contribution
This is the first documented case of Oestrus ovis nasal myiasis in a human with pupation occurring within the host.
Findings
Ten larvae and one puparium were found in the patient’s maxillary sinus.
Diagnosis was confirmed using morphological analysis and DNA sequencing.
Abstract
We report a case of human Oestrus ovis nasal myiasis in Greece, in which pupation occurred within the human host. Ten larvae in various stages of development and 1 puparium were expelled or extracted from the patient’s maxillary sinus. Diagnosis was confirmed through morphologic identification and by PCR, followed by DNA sequencing.
