Orf is a zoonotic viral infection that can affect the hand, often appearing after the feast of the sacrifice. This typically benign condition usually resolves spontaneously with proper diagnosis and reassurance.
Area of Science:
- Dermatology
- Infectious Diseases
- Virology
Background:
- Orf is a zoonotic viral infection caused by a parapoxvirus, transmissible from animals to humans.
- It is an infectious mucocutaneous disease, frequently observed in individuals with occupational exposure, such as veterinarians and butchers.
Observation:
- A case report details a 40-year-old man presenting with a nodular lesion on his finger, which appeared after the feast of the sacrifice.
- Histopathological examination revealed vacuolar degeneration of keratinocytes, suggestive of a viral etiology.
Findings:
- The diagnosis of hand orf was confirmed based on histological findings and reported contact with sheep.
- The lesion resolved spontaneously within three weeks of presentation.
Implications:
- Orf infections, particularly hand orf, may be underdiagnosed, especially following events like the feast of the sacrifice, due to patients not seeking medical consultation.
- Accurate diagnosis can be achieved through electron microscopy, histopathology, or PCR. Patient education regarding the benign nature and spontaneous resolution of orf is crucial for management and reassurance.
