Norwegian scabies

A 67-year old woman with immunosuppression (chemotherapy for a disseminated breast cancer) consulted for a pruritic rash with papulovesicular lesions and squamous lesions on her hands.

The clinical diagnosis was a Norwegian scabies. Many nurses of the department developed a scabies during the following weeks after the entrance of this patient.

Dermoscopy of lesions on her hands revealed a brown triangle (arrows) corresponding
to the head of the mite. If the mite is seen from the dorsal, the triangle appears angulated (see the above picture) or not angulated (►) if it is seen from the ventral site.

On this dermoscopic picture taken from the palmar face, many scales and mites can be seen.
