(A) The cervical stroma with infiltrated small basaloid nests of adenoid basal carcinoma component without stromal desmoplastic reaction (hematoxylin and eosin, ×200). (B) The admixed larger nests of squamous cell carcinoma component with central necrosis, and (C) severe nuclear atypia (hematoxylin and eosin, ×200). (D) The Ki-67 immunohistochemical stain, showing a higher index of staining in squamous cell carcinoma component than adenoid basal carcinoma component (×200).
