1. A cytotechnologist is evaluating a conventional Pap smear preparation from a 34-year-
old patient and observes scattered intermediate squamous cells showing nuclear
enlargement up to three times normal size, hyperchromasia, and distinct koilocytotic
atypia characterized by perinuclear halos. How should this finding be classified according
to the Bethesda System?
A. Negative for intraepithelial lesion or malignancy (NILM)
B. Low-grade squamous intraepithelial lesion (LSIL)
C. High-grade squamous intraepithelial lesion (HSIL)
D. Atypical squamous cells of undetermined significance (ASC-US)
Answer: B
Koilocytic atypia combined with nuclear enlargement and hyperchromasia represents the
hallmark cytomorphological criteria for a low-grade squamous intraepithelial lesion, typically
correlating with human papillomavirus (HPV) infection.
2. During routine processing of a hypercellular cerebrospinal fluid (CSF) specimen using a
cytocentrifuge, the cytotechnologist notices cellular crowding, nuclear distortion, and
artifactual molding across the slide periphery. What is the most appropriate corrective
action for subsequent similar specimens?
A. Increase the centrifugation speed and time to compress cells further
B. Dilute the specimen appropriately with sterile saline or protein-containing diluent to optimize
cell density before cytocentrifugation
C. Skip fixation and air-dry the slides rapidly with high heat
D. Discard the specimen and request a repeat lumbar puncture immediately
Answer: B
Overcrowding in cytocentrifuge preparations obscures nuclear details; diluting hypercellular
fluids prevents artifactual overlapping and ensures diagnostic clarity.
,3. Which of the following fixatives is considered the gold standard for gynecological liquid-
based cytology preparations to preserve delicate nuclear chromatin patterns and prevent
air-drying artifact?
A. 10% neutral buffered formalin
B. Methanol-based fixative solution
C. Absolute acetone
D. Carnoy fixative
Answer: B
Methanol-based fixatives used in liquid-based systems precipitate cellular proteins instantly,
maintaining crisp nuclear architecture and preventing cellular distortion.
4. A sputum cytology specimen processed via the Saccomanno technique reveals abundant
golden-brown, hemosiderin-laden macrophages upon Prussian blue iron staining. What
clinical condition is most strongly suggested by this finding?
A. Acute bacterial pneumonia
B. Chronic left ventricular failure or pulmonary hemorrhage (heart failure cells)
C. Squamous cell carcinoma of the lung
D. Pulmonary alveolar proteinosis
Answer: B
Hemosiderin-laden macrophages, commonly termed heart failure cells, engulf extravasated
red blood cells in alveolar spaces due to chronic pulmonary congestion or hemorrhage.
5. When screening a gynecological specimen, a cytotechnologist observes cells with marked
nuclear pleomorphism, bizarre multi-nucleation, abundant dense orangeophilic cytoplasm,
and keratinization features. Which entity is most likely present?
A. Endocervical adenocarcinoma in situ
B. Invasive keratinizing squamous cell carcinoma
C. Atrophic vaginitis with repair changes
D. Follicular cervicitis
,Answer: B
Keratinization, bizarre cell shapes, and dense orangeophilia on Papanicolaou staining are
characteristic features of invasive keratinizing squamous cell carcinoma.
6. A fine needle aspiration (FNA) of a thyroid nodule yields a cellular smear composed
predominantly of microfollicular arrangements, scanty colloid, and uniform follicular cells
with nuclear overlapping. According to the Bethesda System for Reporting Thyroid
Cytopathology, what is the standard diagnostic category?
A. Bethesda Category II: Benign
B. Bethesda Category III: Atypia of Undetermined Significance / Follicular Lesion of
Undetermined Significance
C. Bethesda Category IV: Suspicious for a Follicular Neoplasm
D. Bethesda Category VI: Malignant
Answer: C
Microfollicular architecture with scant colloid and cellular crowding without definitive
papillary nuclear features falls into the suspicious for follicular neoplasm category.
7. Which Papanicolaou stain component is primarily responsible for imparting
polychromatic staining to squamous cell cytoplasm, highlighting cellular maturation and
keratinization?
A. Harris hematoxylin
B. Orange G-6 (OG-6)
C. EA-36 or EA-50 (Eosin Azure)
D. Aqueous Bismarck brown
Answer: B
Orange G-6 targets prekeratin and keratin proteins, staining them a brilliant orange-yellow to
differentiate superficial cells and keratinizing malignant lesions.
8. In urinary cytology, what cytomorphological feature helps differentiate umbrella cells
(facet cells) from low-grade urothelial carcinoma cells?
A. Umbrella cells are small and hyperchromatic with high nuclear-to-cytoplasmic ratios
, B. Umbrella cells are large, often multinucleated, have abundant cytoplasm, and exhibit bland,
low-grade nuclear features compared to neoplastic cells
C. Umbrella cells lack cytoplasm entirely
D. Umbrella cells stain intensely with mucicarmine
Answer: B
Normal or reactive umbrella cells are large superficial urothelial cells featuring abundant
cytoplasm and bland, regular nuclei, whereas malignant urothelial cells show high N:C ratios
and hyperchromasia.
9. A fine needle aspiration of a salivary gland mass displays uniform epithelial cells
forming duct-like structures and branching tubules embedded within a prominent
chondromyxoid stroma. What is the most definitive diagnosis?
A. Warthin tumor
B. Pleomorphic adenoma
C. Mucoepidermoid carcinoma
D. Adenoid cystic carcinoma
Answer: B
Pleomorphic adenoma (mixed tumor) characteristically exhibits epithelial and myoepithelial
elements set in a distinctive chondromyxoid or myxoid stromal matrix.
10. What is the primary laboratory safety protocol when handling unfixed fine needle
aspiration specimens suspected of containing high-consequence infectious agents?
A. Process specimens on an open benchtop without personal protective equipment
B. Perform all initial specimen manipulations within a certified biosafety cabinet utilizing
appropriate universal precautions
C. Expose specimens to ultraviolet germicidal lamps while pipetting
D. Heat-fix slides immediately using an open Bunsen burner flame near aerosols
Answer: B
Biosafety cabinets protect laboratory personnel from aerosolized infectious agents during the
handling and preparation of unfixed clinical specimens.
