How does CK20 immunostain helps in diagnosing Urothelial Carcinoma in Situ? 👉 Full thickness staining. Reactive urothelium will be positive only in surface umbrella cells or completely negative. #Bladder #GUPath

"Tricky Trich" - Trichomonas Vaginalis is harder to identify when overlapping/clinging to squamous cells. (SurePath, PAP Test)

Without the intranuclear inclusions, these "oncocytoid" cells would have been a bit difficult to be called "Papillary Thyroid Carcinoma" on FNA. Follow-up, "PTC, Tall Cell Subtype".

From silence to song - rose bud and full rose, side by side.

“Cellular whorl”

"Frosted" - Classic ground glass nuclei of HSV. (ThinPrep PAP test)

Another classic appearance - "Perakeratotic-like" cell in pleural effusion of a mesothelioma. (cytospin)

"Pseudomyxoma peritonei" (peritoneal mucinous neoplasia), with high-grade cytology. (Abdominal fluid, young patient with an ovarian mass)

“Eyeballs”. Mega-macronucleoli in a case of Hepatocellular Carcinoma. (FNA)

As agreed previously...once you see it you have to share it 😁😂🤣 #pathology #PathTwitter #dermpath

Although not a classic reason for a "Sister Mary Joseph Nodule", this peri-umbilical mass represents an "Epithelioid Mesothelioma". (FNA, smears and cell block, calretinin IHC)
