This summary is machine-generated.

A patient developed eye swelling after traveling to a Chagas disease area and encountering triatomine bugs. The condition was diagnosed as furuncular myiasis, highlighting other parasitic causes of Romaña sign.

Area of Science:

  • Parasitology
  • Tropical Medicine
  • Clinical Case Reports

Background:

  • Chagas disease, caused by *Trypanosoma cruzi*, is endemic in parts of South America.
  • Exposure to triatomine (reduviid) bugs is a primary transmission route for Chagas disease.
  • Romaña sign, characterized by unilateral periorbital edema, is a classic clinical manifestation of acute Chagas disease.

Purpose of the Study:

  • To report a case of unilateral periorbital edema mimicking Romaña sign.
  • To differentiate between Chagas disease and other potential causes of similar clinical presentation.
  • To emphasize the importance of considering alternative parasitic infections in endemic areas.

Main Methods:

  • Clinical presentation review of a patient with unilateral periorbital edema.
  • Travel history including exposure to triatomine bugs in a Chagas disease-endemic region.
  • Diagnostic workup to rule out *Trypanosoma cruzi* infection and identify the causative agent.

Main Results:

  • The patient presented with unilateral periorbital edema after travel to a Chagas disease-endemic area.
  • Diagnostic investigations confirmed furuncular myiasis as the cause of the edema.
  • *Trypanosoma cruzi* infection was excluded.

Conclusions:

  • Furuncular myiasis can present with clinical features similar to Romaña sign.
  • It is crucial to consider a differential diagnosis beyond Chagas disease in patients with periorbital edema after travel to endemic areas.
  • This case underscores the diversity of parasitic agents that can cause symptoms mimicking Chagas disease.
