- Abstract
- A 32-year-old man was admitted to our hospital due to a headache. A brain CT and MRI showed a parenchymal mass in the right temporoparietooccipital lobe and histopathological specimens demonstrated a proliferating trichilemmal tumor (PTT). Two years prior to experiencing headache, the man had a round mass localized in the right suboccipital scalp which recurred after wide excisions and was found to be PTT. There was no evidence of tumor recurrence at the scalp during the period the man first began experiencing headache. Although PTT usually occurrs at the scalp, direct invasion into the brain is very rare. We report a patient with malignant PTT who developed brain parenchymal inva-sion, which was supported by neuroradiological and histopathological findings.
