On the contrary, juvenile FP revealed male predominance (M:F = 1:0.6), frequent involvement of the trunk (41.2%), and exclusive involvement in skin of color (SOC:White = 11:0). In addition to its unique presentation, FP tends to be misdiagnosed due to its low incidence of concomitant psoriasis (31.8%), and rare personal (18.2%) or family history (6.8%) of psoriasis. Reported histopathological features include keratotic plugging, follicular parakeratosis with or without neutrophils, psoriasiform acanthosis, hypogranulosis, and neutrophilic infiltration of follicular epithelium. Dermatoscopic findings include folliculocentric lesions with normal appearing terminal hairs, perifollicular white scale, and various vascular structures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Once correctly diagnosed, patients with FP showed improvement or resolution of symptoms with various combinations of topical and systemic therapies.
