Figure 2: Histopathological examination, ×10. (a) Histopathology of hyperkeratotic alopecic plaque on scalp showing dilated follicular infundibula with compact hyperkeratotic plug in lower portion. Epitheliumlining the follicular infundibulum showed marked hypergranulosis with vacuolar degeneration of keratinocytes and lichenoid interface dermatitis with follicular scarring. (b) Histopathology of follicular keratotic papules on back showed dilated keratin plugged follicular opening with apoptotic keratinocytes and lichenoid interface dermatitis consistent with lichen planopilaris
