“Cells so ballooned, they look ready to float off the slide.” Two more cases from this morning. Pleural fluids with metastatic ovarian serous (left) and pancreatic adenocarcinoma (right). (cytospin)

[Syed Z. Ali @sza_jhcyto]

“Psammoma bodies; where pathology briefly becomes art.” A rare case from this morning - pleural effusion with metastatic clear cell adnocarcinoma from the patient's known urethral primary. (cytospin)

“Where neuroendocrine cells gather, vessels are rarely far behind.” Metastatic NET from the gut on a liver FNA.

Melanoma in the breast: the ultimate cytologic impostor, "wrong address, convincing disguise.” (FNA)

When you could grab a pencil and draw cytoplasmic borders of individual cells - Classic cytomorphology of "clear cell renal cell carcinoma. (FNA)

[Syed Z. Ali @sza_jhcyto]

“In CSF, size matters the most, especially when the nuclei look guilty.” Metastatic breast lobular carcinoma. (cytospin)

"The survivor". Lung FNA: one ciliated normal bronchial cell among poorly differentiated tumor cells.

[Syed Z. Ali @sza_jhcyto]

Impressive contrast in the appearance of malignant cells from an ovarian serous carcinoma in ascitic fluid. (cytospin)

[Syed Z. Ali @sza_jhcyto]

Thick streaky colloid in a papillary thyroid carcinoma. (Thyroid, FNA)

[Syed Z. Ali @sza_jhcyto]

Partially intact fragment of tumor with malignant epithelium detaching away from the central core - Papillary Thyroid Carcinoma. (Thyroid, FNA)

[Syed Z. Ali @sza_jhcyto]

CLASSIC and gorgeous cytomorphology - a jumbled capillary network weaving through deceptively bland neuroendocrine cells from an intrathyroidal parathyroid neoplasm (adenoma) - "the vascularity and naked nuclei are the clues". (Thyroid, FNA)

[Syed Z. Ali @sza_jhcyto]

Just an impressive ("mushrooming") architecture of a Papillary Thyroid Carcinoma. (Thyroid, FNA)

[Syed Z. Ali @sza_jhcyto]

“Spindle cell melanoma" metastatic to the lung: when the tumor sheds its familiar face and morphology becomes the trap.” (EBUS FNA)

[Syed Z. Ali @sza_jhcyto]

“Undifferentiated Carcinoma", living up to its name: when the cells tell you malignancy, but refuse to tell you what they are. (Lung FNA)

[Syed Z. Ali @sza_jhcyto]

ROSETTING, an architectural whisper of neuroendocrine differentiation in a liver lesion, "Pancreatic Neuroendocrine Tumor (PanNET). (Liver, FNA)

[Syed Z. Ali @sza_jhcyto]

The rare HSIL cells - "elusive, inconspicuous and diagnostically unforgiving". (ThiPrep PAP test)

[Syed Z. Ali @sza_jhcyto]

Pleomorphic adenomas can still look pretty on Pap stain, a case from this morning. (Parotid, FNA)

[Syed Z. Ali @sza_jhcyto]

“Pseudo–signet ring cells in ascitic fluid: a deceptive look that can lead you straight to the wrong diagnosis.”
Hydropic degeneration is known to occur in histiocytes and mesothelial cells.
