The aim of our study is to report and describe the clinical, dermatoscopic and histological characteristics of the PFPT for the first time in a series of Ecuadorian patients. A simple prospective study at the Garzón Dermatological Specialty Center, a two-year period. The inclusion criteria was lingual change of color, demographic, clinical data were collected; photographs, dermatoscopy, and biopsy, for staining with hematoxylin-eosin and FontanaMason. We examined 8,640 patients, 15 (12 women, 3 men) were diagnosed with PFTP. The range of age was 31 years, all were mestizos, with skin phototype predominant III and IV. The range of evolution time in years was 5.8. None had family or personal precedents related to the pathology.
