Rovsing's sign, named after the Danish surgeon Niels Thorkild Rovsing (1862–1927), is a sign of appendicitis. If palpation of the left lower quadrant of a person's abdomen increases the pain felt in the right lower quadrant, the patient is said to have a positive Rovsing's sign and may have appendicitis. The phenomenon was first described by Swedish surgeon Emil Samuel Perman (1856–1945) writing in the journal Hygiea in 1904.
In acute appendicitis, palpation in the left iliac fossa may produce pain in the right iliac fossa.
