Summary
A pinworm (Enterobius vermicularis) was found in a soldier's urine in Nigeria after intercourse. This rare case highlights potential urethral migration of parasites from the perianal region.
Area of Science:
- Urology
- Parasitology
- Infectious Diseases
Background:
- Enterobius vermicularis, commonly known as the pinworm, is a prevalent intestinal nematode, particularly in children.
- Urethral infestation by Enterobius vermicularis is an extremely rare clinical presentation.
Observation:
- A soldier in Ibadan, Nigeria, presented with urethral irritation following sexual intercourse.
- The irritation began approximately 4 hours post-coitus and resolved after the first micturition, which expelled a worm.
Findings:
- Microscopic examination confirmed the presence of an Enterobius vermicularis worm in the urine.
- Evidence suggested the worm entered the urethra from the partner's perianal region during rear-entry intercourse.
Implications:
- This case underscores the possibility of aberrant parasitic migration into the human urinary tract.
- It highlights the importance of considering unusual etiologies for urethral symptoms, especially in regions with high endemicity of common parasitic infections.
