Frank's Sign: A Link Between Dermatovenerology, Cardiac Pathology, and Neurology

Acta Dermatovenerol Croat. 2023 Nov;31(2):101-102.ABSTRACTDear Editor, Although some of my colleagues may find this surprising, as a neurologist, I have noticed many connections between dermatology and neurology. Neurological and dermatological signs and symptoms are common in many clinical entities, especially in the so-called phakomatoses or neurocutaneous syndromes (Von Recklinghausen's disease type 1 and 2, Bourneville-Pringle syndrome, Sturge-Weber syndrome, Von Hippel-Lindau syndrome, Louis-Bar syndrome) (1). The terms "neurodermatitis" and "neurodermatology" also confirm the above. Inspection is the basis of every clinical examination and an integral part of both dermatological and neurological propaedeutics. Therefore, I would like to remind your readers of Frank's sign, another link between dermatology and neurology. Frank's sign is a diagonal earlobe crease (DELC) that extends backwards from the tragus at a 45-degree angle across the lobule to the auricular edge of the ear (Figure 1). It has been described as a dermatological marker for atherosclerosis. Frank's sign is named after Dr. Sanders T. Frank, who observed this crease in 20 patients with coronary artery disease and published his findings in The New England Journal of Medicine in 1973 (2). Although this sign has been known for more than 50 years, it is still not routinely employed in clinical practice. Histopathological examination of DELC-positive earlobes revealed myoelastofibrosis in the arterial vessel a...
