Introduction:
Scabies is a parasitic world-wide dermatosis caused by human ectoparasite Sarcoptes scabiei var. hominis. Crusted scabies is a severe and extremely contagious form of scabies with massive skin infestation. As a result of the clinical presentation not corresponding to the classic scabies, the establishment of a diagnosis is frequently delayed.

Objective:
We highlight the role of dermoscopy in establishing the diagnosis of scabies.

Case report:
We present the case of a 77-year-old nursing home resident with a history of psoriasis for over 30 years with symptoms of generalized erythematous-papular lesions covered by scales, accompanied by palmoplantar regions covered by plaques with linear fissures, onycholysis and subungual hyperkeratosis. The dermoscopic examination revealed “delta wing” sign and numerous aggregates of burrows, allowing to establish the diagnosis of scabies.

Conclusions:
Dermatoscopy as an easily accessible, fast and non-invasive examination can identify typical scabies characteristics, significantly improving the process of diagnosing.
