Background: Malignant proliferating trichilemmal tumor (MPTT) is very rare malignant tumors of hair follicles derived from outer root sheath. This tumor is mostly located on the head and neck of elderly women. Regional or distant metastasis is possible. In this study, we present clinical features and treatment outcomes of cases diagnosed as MPTT. Furthermore, we aimed to emphasize a different clinical form of the tumor that can be misdiagnosed clinically. Patients and Methods: A retrospective evaluation of five cases operated between September 2009 and February 2017 Celal Bayar University Faculty of Medicine, Plastic Reconstructive and Aesthetic Surgery Department at were included in the study. Clinicopathological features of patients, type of surgery, and follow-up information were evaluated. Results: Four patients were female. Average age was 72.2. All of the lesions were located on the head and neck. All patients had a history of rapid growth of lesions. Patients were scanned with computed tomography. There was no metastasis at the time of diagnosis. None of the patients needed adjuvant therapy. Mean follow-up time was 11.8 months. None of the patients developed recurrence or metastasis. Conclusions: These tumors resemble basal cell or squamous cell carcinoma. Rapid progress of benign form of the tumor should address malignant transformation. There is no consensus about adjuvant therapy. Screening for metastasis and close follow-up are mandatory.
