Abstract
Scabies can present in atypical ways, making the diagnosis challenging. This article describes the various forms of presentation and discusses treatment options.
Key Points
- The scabies mite is an obligate human parasite transmitted by skin to skin contact or by contact with contaminated objects.
- Consider the diagnosis in any patient who has generalised pruritus with nocturnal exacerbations.
- The presentation is variable and is influenced by age, immune status, hygiene and previous treatment.
- Permethrin, applied topically, is the first line therapy.
- The itch can persist for two to three weeks after treatment.
- Oral ivermectin is currently approved to treat special forms of scabies only.
