Normal endobronchial epithelial cells

Description: Normal endobronchial epithelial cells. Note the columnar shape of the cells, basally placed nuclei, and terminal bar with well-formed apicalcilia.
ProcedureSource: Bronchial brush
Prep type: Smear
Stain: Pap
Magnification: 630 X
Adenocarcinoma (Pap, high power #1)

Description: Adenocarcinoma. Pleomorphic malignant cells with roundnuclei, vesicular chromatin, and prominent nucleoli.
ProcedureSource: Transthoracic FNA
Prep type: Smear
Stain: Pap
Magnification: 630 X

Small cell carcinoma (sputum)

Description: Small cellcarcinoma. Extensive cellular necrosis with a single cluster of malignant round to ovoid cells appearing as naked nuclei with fine powdery chromatin and lack of nucleoli. Note the prominent nuclearmolding.
ProcedureSource: Sputum
Prep type: Smear

Magnification: 630 X
Toxoplasmosis #1

Description: Markedly increased cellularity as a result of lymphomononuclear cell infiltrate,reactive astrocytes, and numerous fine capillaries. The characteristic pseudocysts are not present in this photomicrograph. Hypercellularity alone may create diagnostic difficulty with malignantglioma.

Prep type: Smear
Stain: Pap
Magnification: 200 X
Toxoplasmosis #2

Description: A large pseudocyst distended with toxoplasma bradyzoites.ProcedureSource: CT guided FNA of brain
