@TingZhaoPathdoc Actually, I still felt it difficult diagnosing in a metastatic lymph node specimen an LEC (rather than a usual SCC if categorized as different entity) of other primary organs, particularly the EBV- one…

@yjywang The primary tumor was basaloid. Check the link below. The lymphoid background in the lymph node might give it a lymphoepithelioma-like appearance. x.com/TingZhaoPathdo…

@MirunaPopescu13 @RazaHoda @fouad_boulos @DanGrahamMD @ChelseaMehr_MD @Janiranavarro @cebulka26 @VHNguyenMD @ziad_zaatari @TingZhaoPathdoc Whoa - that is a new one for me! I will have to add it to the ‘breast spindle cell lesions’ ddx. Thank you, @MirunaPopescu13

#Breastpath #Surgpath #Pathresidents #Pathtwitter Resection of a suspicious breast mass in a 60 year old woman. Take a look at some images, place your vote, and read some discussion.

@Janiranavarro Always throw EMA and S100 and get an equivocally weak and negative result. Then hesitating a GLUT1 as a raffle😅

Colonic perineurioma - Poorly circumscribed spindle cell proliferation, usually confined to the mucosa - Entrapped/overlying colonic crypts appear hyperplastic or serrated - EMA positive, usually weak positivity (Pic 3), S100 negative #pathology #PathX #pathtwitter #everydayGI

The new edition of the globally accepted WHO classification of Digestive System Tumours (blue book) is the subject of this review. The article outlines the important changes succinctly and clearly, with appealing diagrams and relevant images. doi.org/10.1111/his.70… #GIpathology

Here are some reference cases: UC Davis Case of the Month February 2019: health.ucdavis.edu/pathology/educ… UAB Case of the Week January 25, 2021: uab.edu/medicine/patho…

Most cases occurs in the 2nd trimester. Intrauterine fetal demise after GA 8 with retention and mechanical compression for over 10 weeks would make it mummified, resembling a parchment paper.

Preparing specimen for grossing in the afternoon… What would you describe the gross findings of this placenta? (Would take a better picture afterwards😅) #pathtwitter #pedpath #grosspath

@drHTBlungpath @USFpathology @MdWistuba I have also learned it from Dr. Ozgur Mete's talk! Don't use sustentacular cell only to discriminate paraganglioma.

For our residents @USFpathology Can carcinoid tumors show sustentacular cells ? Short answer is yes, particularly peripheral typical carcinoid tumors (better differentiated) pubmed.ncbi.nlm.nih.gov/21323953/ This was described many years ago @MdWistuba #lung #thoracic #Moffittpathology

2nd case: one MPMN in the lepidic pattern of AIS, adjacent to the interlobular septum (other findings: another MPMN at the left lower corner and apical cap at right lower corner) SSTR2a IHC for interest came out today in the 1st case.

Interesting findings make my day! What insidious lesion do the images demonstrate?

those fibrin/PLT >90% -> favored active cancer What about CE and LAA? It could be more difficult. Several studies dig into % composition, but the results are inconsistent. The % are often overlapped and not "clinically significant" enough. Ref: doi.org/10.1007/s00234…

(Note: These applies to "active" cancer.) In the above case, the diagnosis of neurological team shifts toward cancer-related thromboembolism. As the original case with MCA stroke, a lung nodule is found on CXR after hospitalization, and subsequent biopsy reveals a lung adeno.

Similar one upon reviewing my colleague's cases 74M, history of heavily treated lung adenoca with pleural, spinal, and liver mets Found acute ischemic stroke, basilar artery tip to right SCA and bilateral proximal PCAs Neurology team favored large artery atherosclerosis.
