Digital dermoscopy: a complementary method in the diagnosis of scabies

Abstract Scabies is an ectoparasitosis caused by Sarcoptes scabiei var. hominis, characterized clinically by pruritic lesions in typical locations; the crusted form is a rare manifestation. The diagnosis is usually established based on the clinical picture, but dermoscopy can be an important complementary method, as it allows the observation of a brownish triangular structure with a hang-glider appearance. A case of crusted scabies is reported; the magnification of the images obtained by digital dermoscopy allowed the demonstration of a structure usually observed only with videodermoscopy.

Livedoid vasculopathy as a marker of systemic disease: report of two cases

The livedoid vasculopathy is an obstructive vascular process of etiology not yet fully known, being possibly associated with several prothrombotic events. It is clinically characterized by the presence of painful and recurring purpuric lesions, which usually suffer ulceration and evolve with formation of white atrophic scars usually located in the lower limbs. Two cases are here reported of painful ulcerated lesions on the lower limbs, in which the identification of VL enabled the diagnosis of systemic diseases.
