Early-onset folliculitis decalvans and lichen planopilaris phenotypic spectrum: Is it a different disease?

Supplementary figure 2. Histopathological examination of affected scalp in a patient with
folliculitis decalvans and lichen planopilaris phenotypic spectrum showing concentric fibrosis
at level of follicular infundibulum with associated perifollicular lymphocytic inflammation. No
neutrophils or eosinophils are seen. Sebaceous glands are present. A few compound follicles
are noted (hematoxylin and eosin, original magnification: x100).
