title: Recurrent malignant pilomatrixoma invading the cranial cavity: Improved local control with adjuvant radiation.
abstract: We report the case of a 41-year-old mentally retarded male with recurrent pilomatrix carcinoma of the occipital region which invaded the occipital bone, left cerebellum and left temporal lobe. At his initial presentation the patient had a craniotomy and subtotal excision of the lesion with positive margins. He received no adjuvant therapy. After an early intracranial recurrence he had subtotal debulking and was referred for external beam radiotherapy. At 27 months follow-up after adjuvant external beam radiotherapy the intracranial component has not progressed and the patient remains clinically well.
