Glomus tympanicum and Glomus jugulare, also known as jugulotympanic paraganglioma: Both commonly present as a middle ear mass resulting in tinnitus (in 80%) and hearing loss (in 60%). The cranial nerves of the jugular foramen may be compressed, resulting swallowing difficulty, or ipsilateral weakness of the upper trapezius and ...
A glomus tumor (also known as a "solitary glomus tumor" [1]) is a rare neoplasm arising from the glomus body and mainly found under the nail, on the fingertip or in the foot. [2]: 670 They account for less than 2% of all soft tissue tumors. [3] The majority of glomus tumors are benign, but they can also show malignant features. [4]
These tumors can develop on the skin, subcutaneously, or on a blood vessel within an organ and are highly malignant. The tumors are most fatal when they rupture, causing the dog to suffer from severe loss of blood, or hypovolemia. [6] Dogs are one of three mammalian species that are known to suffer from a transmissible cancer. [7]
