Proliferating larval cestodiasis: report of a case
Acta Tropica
|December 1, 1983
Summary
A rare abdominal infection with an undifferentiated cestode larva occurred in a Filipino man in Canada. This parasitic infection caused a significant inflammatory response within a lymph node.
Area of Science:
- Parasitology
- Infectious Diseases
- Histopathology
Background:
- Cestode infections can manifest in various forms, including larval stages that may infect human tissues.
- Undifferentiated larval cestodes, such as spargana or tetrahydia, pose diagnostic challenges.
Observation:
- A 72-year-old Filipino immigrant in Canada presented with an abdominal infection.
- Parasitic organisms, identified as undifferentiated larval cestodes, were found within a lymph node.
- The parasites induced a localized fibrogranulomatous and eosinophilic inflammatory reaction.
Findings:
- The morphology of the parasite suggests it is an undifferentiated sparganum or tetrahyridium.
- Comparison with similar cases from Taiwan and Paraguay supports the identification.
Implications:
- This case highlights the potential for zoonotic cestode infections in new geographic locations.
- Accurate identification of larval cestodes is crucial for appropriate clinical management and public health surveillance.
- Further research into the epidemiology and diagnostics of these infections is warranted.
