Different types of scabies have been described based on their clinical outcome, one of which is the Crusted (Norwegian) type. This is an extreme manifestation of scabies that can be observed mainly among immunosupressed patients. A case ofa 42 year-old homosexual man is described. The patient was diagnosed with HIV, presenting pruritic lesions with a 4 month evolution in trunk and extremities. Lesions included xerosis, decapitated papules, badges with erythema, residual hyperchromic stains, multiple abrasions and ungueal pigmentation in both feet. At the beginning it was treated as apsorasiform dermatitis with steroids and antipruritics without success. Through a biopsy the suspected diagnosis of Crusted (Norwegian) scabies was confirmed. The patient was treated with a dose of oral ivermectin and topical benzyl benzoate and showed remission after two days.
