Abstract: Proliferating Trichilemmal tumors (PTT) are rare neoplasms of the external root hair sheath that are largely benign. The potential for PTT to undergo transformation to a Malignant Proliferating Trichilemmal Tumor (MPTT) is very rare. In this case report we discuss the diagnosis, histo-pathological characteristics, and surgical treatment of such tumors.
