Proliferating trichilemmal tumor (PTT) is a rare, mostly benign neoplasm which stems from the follicular outer root sheath epithelium. PTT occurs as a subcutaneous cystic nodule slowly enlarging to a larger noduler mass, and is usually localized on the scalp of elderly women. To the best of our knowledge, PTT localized on a psoriatic plaque has not been reported previously. Herein, we report an unusual case of benign PTT arising from a psoriatic plaque on the knee of a 63-year-old male patient. Keywords: proliferating trichilemmal tumor, psoriasis, trichilemmal cyst
