Hatchcock’s Sign


DefinitionUpward pressure applied to the angle of mandible produces pain with parotitis, but not with adenitis

Clinical Significance – This particular sign could be positive before any significant parotid gland swelling occurred and would aid in the early detection and diagnosis of mumps. 

History – First described by a Lieutenant Hatchcock in 1918.  Honestly, I can’t find much on this Lieutenant Hatchcock……
