Question:
Reportability/Histology--Brain and CNS: Is epidermoid tumor of the cerebellopontine angle (CPA) and trigeminal vesicle nerve reportable, and if so, what is the correct histology code? See discussion.
Discussion:
Patient presented to hospital ED and had brain MRI that revealed 3.2 cm space occupying lesion in region of the left CPA and trigeminal vesicle nerve compatible with epidermoid tumor.
Answer:
Epidermoid tumor of the brain is not reportable. There is no ICD-O-3 code for epidermoid tumor or epidermoid cyst. This type of tumor is often referred to as a cyst because it has a thin wall that secretes a soft material into the center.
