An impressive cell block preparation from a peritoneal fluid #CytoPath specimen in a patient with history of papillary renal cell carcinoma. What #IHC (s) would you order to confirm the diagnosis?

A cell block preparation from a lung nodule FNA in an older man with history of multiple myeloma. Notice the variably sized structures in the H&E stain, which are highlighted by GMS stain. Mucicarmine stain demonstrates the mucin capsule. Diagnosis? #CytoPath

Dr. Zubair Baloch (@aakasharmand) explaining a helpful cytologic clue to reactive pneumocytes in acute/subacute lung injuries. Their resemblance to Napoleon Bonaparte's iconic hat. Initially described by @natasharekhtman 🔗 to the article👇: https://t.co/XiuvQ8GPyI #IACTutorial

Pleural fluid in a patient with history of of #AML. It’s imperative to review the peripheral blood flow cytometry or smear in cases with abundant red blood cells. Some of these cells are suggestive of blasts; however, peripheral blood contamination cannot be excluded. #CytoPath

Pleomorphic carcinoma, lung: Note: this is the thoracic WHO term for sarcomatoid carcinoma. As usual, they threw out a good term that everyone understands for awful, inane terminology.This case also... https://t.co/7admmThTsJ

Interesting morphology of a squamous cell carcinoma metastatic to the pleural cavity (not common to see SqCC in an effusion #CytoPath specimen). Some of the cells have vacuolated and wispy cytoplasm. Note the combo stain for p40/DSG3. The lung tumor had a papillary architecture.

#yourdailyGleasongrading is back with a quizz 😁... Guess how was this tiny cancerfocus measuring 1 mm graded? I hope it is visible that the glands are perineural...The last picture is p63 (brown)-AMACR (red) IHC 👇👇 #GUpath #pathology
