Named after | Eugene Ludovic Christian Hertoghe |
The sign of Hertoghe or Queen Anne's sign is a type of madarosis, more specifically a thinning or loss of the outer third of the eyebrows, and may appear in severe hypothyroidism or atopic dermatitis. [1] [2] [3] It was also observed in lepromatous leprosy, secondary syphilis, [4] [5] hypoparathyroidism, [6] poisoning with either lead or thallium, lupus, or normal aging. [7]
The sign is named after the Belgian internist Eugene Ludovic Christian Hertoghe (April 5, 1860–January 3, 1928), who was a native of Antwerp, and was the first pioneer in thyroid function research. [2] [3] [8]
The association with Anne of Denmark is based on portraiture, although history does not suggest that she suffered an underactive thyroid. [9] The eponym is disputed by some, [10] though it has been suggested that Anne of France, Anne of Brittany, Anne of Austria, Anne Boleyn and Anne of Cleves may all be eliminated as candidates. [11]
