Orf with unusual features.

Area of Science:

• Dermatology
• Infectious Diseases
• Virology

Background:

• Orf virus (ORFV) typically causes self-limiting skin lesions, often associated with direct contact with infected sheep or goats.
• While Orf is generally considered a zoonotic disease linked to livestock, non-traditional transmission routes require investigation.

Observation:

• A case of Orf in an immunocompetent adult male with no history of direct farm animal contact is presented.
• The patient exhibited numerous, large lesions on hands and feet, including subungual involvement, and later developed atypical lesions on the trunk.
• The unusual clinical presentation prompted diagnostic consideration beyond typical Orf manifestations.

Findings:

• Clinical suspicion of Orf was confirmed through histopathological examination.
• Contact with contaminated soil is proposed as the likely source of infection, given the virus's environmental survival capabilities.
• The case underscores the possibility of Orf transmission through environmental exposure, not solely direct animal contact.

Implications:

• This case broadens the understanding of Orf transmission routes, suggesting environmental contamination as a potential pathway.
• Recognizing unusual clinical presentations of Orf is crucial for accurate diagnosis and to prevent misdiagnosis or unnecessary interventions.
• Increased awareness of Orf's diverse clinical spectrum is important for healthcare professionals, particularly in regions with agricultural activity.
