Diagnostic Cytology
Fig. 13.100 Small-cell carcinoma, oat cell type. The characteristic features
of oat cell carcinoma, including nuclear molding, hyperchromatic granular
chromatin, and high nucleocytoplasmic ratios are seen. Bronchial brushing
(Papanicolaou x MP).
Fig. 13.101 Small-cell carcinoma, oat cell type. Note the presence of
nuclear pyknosis, hyperchromasia, and nuclear molding. Bronchial brushing
(Papanicolaou x OI).
Fig. 13.102 Small-cell carcinoma, oat cell type. Bronchial brushing
(Papanicolaou x OI).
Fig. 13.103 Small-cell carcinoma. Bronchial brushing (Papanicolaou x OI).
Fig. 13.104 Cells derived from small-cell carcinoma exhibiting nuclear
molding. Sputum (Papanicolaou x MP).
Fig. 13.105 Cells derived from Ewing's sarcoma. The high
nucleocytoplasmic ratios and focal nuclear molding in this field call to
mind features of small-cell undifferentiated carcinoma. Bronchial brushing
(Papanicolaou x OI).
