Two Cases of Scabies Located Exclusively on a Toenail: A Case Report.

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.
