Abstract
Prolifere trikilemmal tümör PTT foliküler dış kök kılıfı epitelinden köken alan nadir, çoğunlukla benign bir neoplazmdır. PTT yavaşça büyük nodüler bir kitle olarak genişleyen subkutan kistik nodül şeklinde oluşur ve genellikle yaşlı kadınların saçlı derisinde lokalizedir. Literatürde daha önce kronik psoriazis plağı üzerinde gelişen PTT bildirilmemiştir. Bu olgu sunumunda 63 yaşında erkek hastanın diz bölgesindeki kronik psoriazis plağı üzerinde gelişen benign PTT bildirilmiştir.

An Unusual Presentation of Proliferating Trichilemmal Tumor Developing in Psoriatic Plaque: A Case Report
Abstract
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.
