Abnormal cellular component in pap Flashcards
Budding yeast seen among diabetics, taking oral contraceptives, immunocompromised patients, prolonged steroid therapy; also called moniliasis
Candida albicans
Pear-shaped organism, STD, granular cytoplasm, eccentric dark nucleus
Trichomonas vaginalis
Tiny pleomorphic coccobacilli that cling to the cytoplasm of epithelial cells
Gardnerella vaginalis
Squamous epithelial cell that shows cytopathic effects of HPV; nucleus appears as a wrinkled prune surrounded by a perinuclear halo
Koilocytes
Presence of koilocytes diagnosed as low-grade squamous intraepithelial lesion
Low-grade squamous intraepithelial lesion
Cytopathic effect characterized by macrosomia, multinucleation, nuclear molding, and ground-glass chromatin pattern
HSVII
Epithelias associated with cancerous lesions
Carcinomas
Cervical mucus in pregnancy; on drying exhibits a fern or palm tree leaf pattern due to increased estrogen effect
Ferning arborization
Formation of salt crystals (high NaCl concentration) under the influence of estrogen
Basis of ferning pattern
High persistent estrogen effect in the absence of progesterone; basis for early pregnancy diagnosis
Positive ferning
Marked progesterone effect, at least 50% of intermediate cells in clusters, presence of 3-7 pregnancy cells, less than 30% superficial cells, presence of Doderlein bacilli
Criteria for cytologic diagnosis of normal pregnancy
Percentage of cells that stain pink-orange to red with Pap’s stain and red with Shorr method
Acidophilic index (A.I)
Percentage of cells having shrunken dark, small (<6 µm) nuclei
Pyknotic index (P.I) / Karyo-pyknotic index
Percentage proportion of cells from the three layers of the vaginal epithelium
Maturation Index (M.I)
Two systems: Class system (obsolete since December 1988) and Bethesda system (developed at NCI)
Manner of reporting Pap smears
Obsolete system based on the presence of malignant cells; no classes for non-cancerous entities; not reproducible
Class system
Negative for malignant cells
Class I
Atypical cells present but negative for malignancy
Class II
Suspicious for malignant cells
Class III
Strongly suggestive for malignant cells
Class IV
Conclusive for malignant cells
Class V
Developed at the National Cancer Institute in December 1988; includes specimen adequacy, general categorization, and descriptive diagnosis
Bethesda system
Categories: satisfactory, limited, unsatisfactory
Specimen adequacy (Bethesda system)
Negative for intraepithelial lesion or malignancy; epithelial cell abnormality; benign cellular changes
General categorization (Bethesda system)
Includes infectious/radiation effects, atypical squamous cells of unknown significance, low- and high-grade squamous intraepithelial lesions, squamous cell carcinoma, glandular cell abnormality, atypical glandular cells, adenocarcinoma, others
Descriptive diagnosis (Bethesda system)
