Subungual schwannoma with clinical, sonographic, and histologic correlation.

We show an unusual presentation of a schwannoma that was located in the ungual bed of the left great toe. The clinical, color Doppler ultrasound imaging, and histologic findings are shown to illustrate the case. This type of neurogenic tumor and the ultrasound presurgical imaging support should be considered when dealing with subungual tumors of the foot.

Dermanyssus gallinae (chicken mite): an underdiagnosed environmental infestation.

Dermanyssus gallinae is a mite that normally parasitizes small birds but may occasionally bite humans. We report an unusual case of an 82-year-old woman who presented with pruritus and bite-like lesions over her trunk. Other members of the household were also affected.
