FIVE Fascinating Facts About Auer Rods Auer rods are more than just pink needles in blasts. A thread…🧵

Organ? Dx? #PathX #PathTwitter

50/post menopausal female, D&C material. Mass present in anterior uterine wall. Presents with bleeding, ascites, skeletal mets in d2-d3 vertebrae. #Gynpath #Pathology #Pathresidents #PathX #Pathologists #Pathtwitter #Surgpath

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

Seen in necrotizing granulation tissue in superficial arm mass of 20s F. Mysterious objects are lurking. Can you name them? #fungus #PathX #PathTwitter #pathbugs

Ironclad: hepatic hemochromatosis Coarse golden-brown iron granules (initially Zone 1 hepatocytes if primary/HH) ±hepatocyte damage. Periportal fibrosis (bridging) > micronodular cirrhosis (seen on low power) Iron should usually be confirmed w/ Prussian blue stain. #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

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

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
