Matchbox sign
Matchbox sign
The Matchbox sign (pronounced: /ˈmætʃ.bɒks saɪn/) is a term used in dermatology to describe a specific clinical finding often associated with scabies.
Etymology
The term "Matchbox sign" is derived from the practice of patients collecting skin scrapings in a matchbox to present to their doctor. This behavior is indicative of the intense pruritus (itching) and the desperate attempts to find relief that are characteristic of a scabies infestation.
Definition
The Matchbox sign is a clinical sign that is positive when a patient presents with a collection of skin scrapings or debris, often in a matchbox or similar small container. This is typically due to the intense itching caused by scabies, leading the patient to scratch and collect the resulting debris.
