Pastia's lines
Pastia's lines (pronunciation: pah-stee-ahz lines) are a clinical sign often associated with Scarlet Fever, a disease caused by infection with the Group A Streptococcus bacterium.
Etymology
The term is named after the Romanian pediatrician, Henric Streitman Pastia, who first described the sign in 1921.
Definition
Pastia's lines refer to the bright red, linear petechial rash that appears in the skin folds, particularly in the axilla (armpit), antecubital fossa (inside of the elbow), and groin. These lines persist even when the generalized rash of scarlet fever fades.
