Introduction:
Nail involvement in patients with crusted scabies is well known. It is characterized clinically by subungual hyperkeratosis and onycholysis. "Classical" scabies involving the nails was rarely reported.
Case Presentations:
We describe 2 patients with classical scabies located exclusively on a toenail. In the first patient, the complete disappearance of the nail plate was observed. In the second patient, a thick, greyish-brown nail plate, surrounded by scales, was observed. Both patients were successfully treated with permethrin and ivermectin.
Conclusion:
A possible explanation about the fact that scabies remained limited to only one toenail is suggested.
