Spider Spines Detected by Dermoscopy

Arch Dermatol. 2006;142(11):1508-1518. doi:10.1001/archderm.142.11.1517

Dermoscopy is a noninvasive technique that improves the diagnostic accuracy for pigmented lesions.1 Recently, it has also been reported to be of use in the diagnosis of some zoonotic infestations like tungiasis and scabies.2,3 In the latter, dermoscopy allows the identification of a triangular structure that corresponds to the anterior section of the mite including the mouth part and the 2 pairs of front legs.3 We report a case in which dermoscopy helped to clarify the diagnosis in a papular reaction that mimics scabies.
