Summary
Enterobius vermicularis, a common pinworm infection, typically affects the intestines. This report details a rare case of enterobiasis found in the salivary glands of a 62-year-old man.
Area of Science:
- Parasitology
- Human Pathology
- Sialadenitis
Background:
- Enterobius vermicularis (pinworm) infection is a common intestinal parasitic disease, primarily affecting children through oro-fecal transmission.
- While typically found in the gastrointestinal tract (cecum, appendix, ileum, colon), rare extra-intestinal cases have been documented.
Observation:
- A 62-year-old male presented with a mass in the right submandibular triangle.
- Histological examination of the removed submandibular gland revealed granulomatous sialadenitis.
Findings:
- The granulomatous inflammation was confirmed to be caused by Enterobius vermicularis.
- This represents an exceptionally rare site for pinworm infection, likely the first reported instance in human salivary glands.
Implications:
- This case highlights the potential for unusual presentations of common parasitic infections.
- Understanding rare ectopic localizations of Enterobius vermicularis is crucial for accurate diagnosis and management.
- Further research into pathogenic mechanisms for extra-intestinal enterobiasis is warranted.
