  Fig. 1 A solitary asymptomatic 6-mm sized, flesh-colored, dome-shaped nodule on the left postauricular area.

  Fig. 2 (A) The epithelial component was surrounded by dense, laminated, collagenous fibroplasia and the fibroepithelial unit was separated by a cleft-like space (H&E, ×40). (B) Mesenchymal stromal components: fibrous tissue with increased blood vessels and mucin deposition, with occasional foci of adipocytes (H&E, ×100). (C) Secondary hair follicles connected to the cystic wall (H&E, ×100).
