Figure 4From: DNA aneuploidy as a topographic malignant transformation pattern in a pleomorphic adenoma of long-term evolution: a case report Histological and immunohistochemical evaluation of superficial areas (groups 1 and 2). (A) Hematoxylin and eosin staining showing cords and islands of polygonal cells without atypia in a myxoid stroma (200× magnification). (B) Basal and myoepithelial cells highly exhibited α-SMA (200× magnification). (C) Slight positivity with CK 8 was observed (200× magnification). (D) No expression was observed with p53 (200× magnification). (E) Basal and myoepithelial cells highly exhibited p63 (200× magnification). (F) Slight positivity with CKs AE1/AE3 was observed (200× magnification). (G) Only occasional cells were positive with antigen Ki67 (100× magnification).Back to article page
