Normal cervical Papanicolaou (Pap) smear. Large squamous cells from the superficial, and intermediate layers of the epithelium are illustrated. The cells have abundant cytoplasm, which varies in staining from pink to blue. The nuclei are small, and the nuclear-cytoplasmic ratio is low. The most superficial cells have pyknotic nuclei (arrows).Credit: Image from Rubin E MD and Farber JL MD. Pathology, 3rd Edition. Philadelphia: Lippincott Williams & Wilkins, 1999.
