Abstract
- Norwegian, or crusted scabies, is a fulminant and highly infectious form of scabies in which a large number of Sarcoptes scabiei mites infest the epidermis. This is often seen in the physically or mentally handicapped, immunocompromised, and institutionalized persons. The characteristic skin lesions in this form are gross scaling and hyperkeratotic plaques with erythematous papules, especially on hands, feet, elbow, and subungual area with varying degrees of pruritus. It may be difficult to differentiate Norwegian scabies from tinea unguium when Norwegian scabies involves nail and subungual area. We report a case of tinea unguium hidden by Norwegian scabies with nail involvement in a 71-year-old patient. This is the first report of such a case in Korea.
