title: Malignant Proliferating Trichilemmal Tumor Treated with Radical Radiotherapy: A Case Report and Literature Review.
abstract: Reported here is the first case of a malignant proliferating trichilemmal tumor treated with radical radiotherapy. Complete clinical response was achieved, and this obviated the need for aggressive surgery. These tumors have a tendency to develop in older patients, and have a propensity for affecting women more than men. The standard of treatment is surgical excision with a margin of normal tissue. Given that not all patients are good surgical candidates, the role of different treatment modalities in the management of this tumor is discussed.
