Figure 3: (a) Histopathology of lower limb shows mild follicular hyperkeratosis and perifollicular lymphocytic infiltration involving infundibulum and isthmus portions of single hair follicle. (H and E, ×40) (b) Histopathology of beard (hematoxylin-eosin; original magnification ×10) shows infundibular lichenoid dermatitis with vacuolar interface changes. (H and E, ×100) (c) Dermoscopy of limb: Loss of orifices and peripilar white concentric scales around the emergence of a follicle. (d) Dermoscopy of beard: Loss of orifices with no other specific findings
