Case for diagnosis
A 70-year-old male patient with a prior history of diabetes and hypertension presented\nwith hyperkeratotic, erosive nodules scattered over the trunk and limbs, scratching\nlesions and marked scaling, with two months of evolution. The palms, bilaterally,\npresented honey-colored crusting and burrows (). He complained of pruritus, mainly at night, but there was no\nepidemiological context of infestation. He was hospitalized to treat a cellulitis in the\nright leg. On dermoscopy (Dermalite Pro II) we observed burrows in the palm of the hand,\nwith identification of a mite in its extremity (). Light microscopy of skin scrapings (after 10% potassium hydroxide) of one\nof the burrow allowed a better view of the agent ().
