Primary axillary hydatid cyst
Summary
Echinococcosis, a parasitic zoonosis, rarely affects the axilla. This case report details a 60-year-old woman with a primary axillary hydatid cyst, highlighting this unusual presentation of Echinococcus granulosus infection.
Area of Science:
- Parasitology
- Infectious Diseases
- Radiology
Background:
- Echinococcosis is a zoonotic disease caused by Echinococcus granulosus larvae.
- The parasite typically affects the liver and lungs, with axillary involvement being exceptionally rare.
- Endemic regions include Canada, Australia, South America, and the Mediterranean.
Observation:
- A 60-year-old woman presented with a primary hydatid cyst in the axilla.
- Axillary hydatid disease is extremely rare, with only 12 documented cases in the literature.
- This represents the first reported case in the authors' country.
Findings:
- The patient underwent a successful total cystectomy for the axillary hydatid cyst.
- Diagnostic imaging confirmed the cyst's location and characteristics.
- Histopathological examination confirmed Echinococcus granulosus.
Implications:
- This case expands the known spectrum of Echinococcus granulosus presentation.
- Highlights the importance of considering rare diagnoses in endemic areas.
- Contributes to the limited literature on axillary hydatid disease, aiding future clinical recognition.
