🚩Psammomatous calcification in ascitic fluid (Pap) Lamellated concentric rings Classically associated w/ serous carcinoma (ovary/Gyn tract) Look for an epithelial component (supporting malignancy; peritoneal involvement) Also consider RCC, PTC, other papillary #PathTwitter

50s F duodenal polyp in 2nd portion. Thoughts? #GIpath #PathTwitter #PathX

Spherule-thyroid FNA (DQ) Round cohesive cluster of follicular cells forming 3D sphere ±colloid Note bland nuclei, smooth contours Supportive of benign Dx (contextual) Contrast to microfollicles (<15 cells, scant colloid, tight sphere), suggesting follicular lesion #PathTwitter

Bubble-wrapped🫧 tumor cells of papillary RCC in a FNA kidney (DQ, CB) Loosely cohesive papillary clusters of cells w/ round uniform nuclei, closely associated w/ foamy macrophages ±hemosiderin ±psammoma bodies Workup: CK7, AMACR, CD10 MET mutations (hereditary form) #PathTwitter

Organ? Dx? #PathX #PathTwitter

Phantom yeasts: treated Cryptococcus in CSF (Pap) Note round empty spaces/halos (only capsule may remain post-Rx, major virulence factor), distorted yeast forms (poorly stained) Minimal inflammation (immune compromise CD4 <100) Mucicarmine, India ink (negative stain) #PathTwitter

Metaplastic transformation of a #glioblastoma is relatively uncommon, but when it happens it's striking. Like this case, where the #GBM is transforming into bone. #pathology #neuropath #pathtwitter

A ser(i)ous identity crisis: Metastatic breast carcinoma in pleural fluid Malignant epithelial cells distinct from mesos (look for clusters, loss of polarity, nuclear pleomorphism ±nucleoli) Intracytoplasmic vacuoles or mucin Origin workup: GCDFP-15, mammaglobin, ER #PathTwitter

A middle-aged female patient with a brain lesion, known to be medically free. In this case, what should be our initial thoughts? And what is the top differential diagnosis? #PathTwitter #Neuropath (1)

Submucosal syncytium: Granular cell tumor of esophagus 🔴Pseudoepitheliomatous hyperplasia of overlying mucosa (🚫SCC) Granular eosinophilic cytoplasm (lysosomes) Indistinct cell borders, ±interspersed blood vessels (🚫vascular lesions) Schwann cell origin (S100+) #PathTwitter

Ecchordosis Physaliphora, a hamartomatous lesion of notochord remnants. IHC identical to chordoma. Unlike chordoma it 1) Benign 2) No growth potential 3) No lobular architecture #pathx #pathtwitter #neuropath #neuropathology #cnspathology
