Pseudo-Romaña Sign Due to Botfly Infestation.

We report a patient who presented with unilateral periorbital edema after a short-term travel to an endemic area for Chagas disease and exposure to triatomine (reduviid) bugs. The diagnosis, however, was furuncular myiasis, not Chagas disease. This case emphasizes that there are multiple parasitic agents besides that may be associated with clinical findings consistent with Romaña sign.
