成長が緩除であった鼓室型グロームス腫瘍例 A Case of Slow-Growing Glomus Tympanicum Tumor
A slow glowing glomus tympanicum tumor was found and surgically removed in a 69-year-old man. He initially consulted an ENT clinic complaining of fullness of the ear and tinnitus in 1997. Red tinge of the eardrum caused by an intratympanic tumor was noted at that time. Though the signs and symptoms had not deteriorated, the patient was referred to our clinic on suspicion of the glomus tumor 8 years later in 2005. A soft tissue density mass measuring 2.5mm was found on the promontory on 2mm thick axial CT image but hearing and tympanometry remained normal. In April 2006, the tumor was successfully removed from the promontory without any residual complications. Histological and immuno-histochemical study confirmed the diagnosis. The natural history and the growth rate of the tumor are discussed.
