MEMORANDUM

DSQC #2007-05

CATEGORY:            CLARIFICATION    

SUBJECT:               REPORTABLE BENIGN SCHWANNOMAS

EFFECTIVE:            CASES DIAGNOSED 1/1/2004 FORWARD

As a clarification, only benign Schwannomas (9560/0) of the cranial nerves are reportable to the CCR.  Benign Schwannomas occurring in the spinal cord, peripheral nerves or peripheral nerve root are not reportable to the CCR. 

The cranial nerves are composed of twelve pairs of nerves that emanate from the nervous tissue of the brain.  Cranial nerves are sometimes referred to by their number, such as the 8th cranial nerve, instead of the vestibulocochlear nerve. 

To assist registrars with identifying reportable benign Schwannoma tumors, the cranial nerve numbers, names and their ICD-O-3 topography codes are listed below:

I           Olfactory (C72.2)

II         Optic (C72.3)

II         Oculomotor (C72.5)

IV        Trochlear (C72.5)

V         Trigeminal (C72.5)

VI        Abducens (C72.5)

VII      Facial (C72.5)

VIII     Vestibulocochlear (auditory and vestibular nerve) (C72.4)

IX        Glossopharnygeal (C72.5)

X         Vagus (C72.5)

XI        Accessory (C72.5)

XII      Hypoglossal (C72.5)

Example of a reportable Schwannoma:

• Vestibular Schwannoma, also known as acoustic neuroma (C72.4 M-9560/0)

Registrars are not expected to go back and review Schwannoma cases already submitted to the CCR.
