A rare case of orf, a zoonotic viral disease, was diagnosed in a 59-year-old man without animal contact. Diagnosis was confirmed via electron microscopy of an ulcerating lip lesion.

Area of Science:

  • Veterinary Medicine
  • Human Medicine
  • Zoonotic Diseases

Background:

  • Orf virus (ORFV) typically affects sheep and goats, causing skin lesions.
  • Human orf infection is usually acquired through direct contact with infected animals or contaminated materials.
  • Unusual transmission routes and atypical presentations warrant further investigation.

Observation:

  • A 59-year-old man presented with a solitary, ulcerating lesion on his upper lip.
  • The patient denied any direct contact with farm animals or contaminated environments.
  • The lesion's appearance and the patient's history were atypical for orf.

Findings:

  • Electron microscopy of a lesion smear confirmed the presence of orf virus.
  • The diagnosis was established despite the absence of a clear epidemiological link to livestock.

  • Differential diagnosis considered other common lip lesions.

    • Implications:

    • This case highlights the potential for orf transmission through indirect or unrecognized routes.
    • It underscores the importance of considering orf in the differential diagnosis of unusual facial lesions, even without a history of animal contact.
    • Further research into non-traditional transmission pathways of orf virus is recommended.
