We report on our histological experience in 47 patients with lichen planopilaris/frontal fibrosing alopecia. Besides presenting the spectrum of clinical appearance of the disease we emphasize the importance of vertical histologic sections of biopsies in the clinicopathological work-up of these patients and give precise histologic criteria and clues in different stages of the disease. Immunohistologically, we found a marked reduction of epithelial Ki-67 expression next to the inflammatory process especially evident in advanced stages of disease.
