Oligosymptomatic glomus tympanicum and caroticium with two different histological pictures.

Though glomus tumors have been relatively frequently reported, there is very little material about their differential diagnostic problems. The authors present a case of glomus tympanicum and glomus caroticum with only otological symptoms, facial paralysis and traumatic arterio-venous shunts in the neck. These two tumors had few different patterns of glomus tissue.
