Question
Reportability--Head & Neck: Is a glomus tympanicum tumor of the middle ear reportable? If so, what are the correct topography and histology codes?

Discussion


Answer
Glomus tympanicum tumors of the middle ear are not reportable. The 2005 WHO Classification of Head and Neck Tumors classifies these as /1 behavior and places them in the ICD-O-3 histology code of 8690: glomus jugulare tumor, NOS. According to WHO, "the distinction between jugular and tympanic paragangliomas can easily be made in the patient by modern imaging methods ... the jugular neoplasm is identified as arising from the jugular bulb region ... while the tympanic neoplasm is confined to the middle ear." Middle ear is C301 and is not one of the reportable sites for benign and borderline neoplasms.
