Figure

• 

  Fig. 1 (A, B) Cutaneous examination revealed multiple yellowish to skin-colored annular, depressed macules on both cheeks.

• 

  Fig. 2 (A) Biopsy specimen of left cheek reveals atrophic epidermis with upper and mid dermal cellular infiltration (H&E, ×40). (B) Tumor strands embedded in dense fibrous stroma are composed of small basaloid cells one to two cells thick (H&E, ×200). (C) Keratinous cysts adjacent to the basaloid cells are observed (H&E, ×200). (D) Biopsy of a right cheek lesion shows cellular infiltration, horn cysts, and calcifications in upper and mid dermis (H&E, ×40). (E) Narrow strands of tumor cells of small basaloid cells with focal calcification are similar to the histopathologic findings of left cheek (H&E, ×200). (F, G) Immunohistochemical staining for CK19 was negative and CK20 showed focal positivity (F: CK10, ×200; G: CK20, ×400).
