Bone marrow leishmaniasis in a 50 yo patient who's undergone liver transplantation! CD1a beautifully highlights amastigotes 🤩 @JMGardnerMD @TristanRutland7 @DrGeeONE #pathology #bonemarrow #parassitology

@MahrukhMumtaz9 I'll give it a try.. A- aspirate clot (?) B- biopsy (H&E) C- touch imprint D- bone marrow aspirate E- unstained bone marrow aspirate

Bone Marrow case done by me. What are slides A-E? Post your answer in the comments below. #pathology #hematology #hematopathology #MedTwitter #PathTwitter

Is this a common pattern observed in treated Ewing sarcomas of the bone? Viable tumor consisted exclusively of perivascular rosette-forming clusters! @JMGardnerMD @JLHornick

Here's my first case of appendiceal goblet cell adenocarcinoma! Further sampling revealed cell clusters floating in extracellular mucin (high grade feature). How many cases have you come across in your practice so far? @DrGeeONE @MirunaPopescu13 @TristanRutland7 #pathology

24 yo boy with testicular torsion. Within rete testis columnar cells with cribriform architecture and pseudoinvasive features are found. These findings are suggestive of adenenomatous hyperplasia of rete testis! #GUpittfals #pathology @DrGeeONE @MirunaPopescu13 @tri

Great lecture on challenging mesenchymal neoplasms of the GI tract from Prof. @JLHornick! 🔬 #ESP #pathology #ESPCongress #Florence #FortezzaDaBasso

@MirunaPopescu13 At first glance I got a sort of Sucquet Hoyers canal vibe

@MirunaPopescu13 Glomangioma?

It's time for a cute #GUPath quiz. Middle-aged M, TURBT specimen, bladder neck/floor. Polypoid mucosa at cystoscopy. 🔬 What's your diagnosis? Answer & short #Tweetorial to follow tomorrow in the🧵 Colleague's case 🙏🏻 #PathTwitter

Has anyone ever seen a better histological picture of Schmidt Lanterman cletfs? 🤓 @DrGeeONE @fouad_boulos @JMGardnerMD @TristanRutland7 @studyhistology

The bizarre cells are PAS positive (shown here) and negative to Grocott stain. Final diagnosis: amebic liver abscess! Shown here are Entamoeba histolytica trophozoites with ingested red blood cells

Resection of the IV hepatic segment: wall of an abscess cavity lined by necrotic-inflammatory tissue containing the same macrophage-like cells. Each element presents with one or multiple eosinophilic globules in the cytoplasm

49 yo female patient with hepatic lesions suspected for metastatic colon cancer. Colonic mucosal biopsy reveals normal intestinal epithelium adjacent to necrotic material containing macrophage-like cells 📸 #PathTwitter #pathology @DrGeeONE @TristanRutland7 @JMGardnerMD

Clinical presentation: skin nodule on the forearm of a 58 yo female patient. Histology: primary cutaneous adenoid cystic carcinoma! Note the presence of distant PNI at surgical margin 😱 @JMGardnerMD @TristanRutland7 @DrGeeONE #pathology #PathTwitter #dermatopathology

@VitorStevam_ have a try with loving your mind instead

CD20 staining reveals the presence of mature B cells infiltrating the bone marrow, forming an aggregate and perisinusal Indian files, typical of Marginal Zone Lymphoma (MZL). @JMGardnerMD @TristanRutland7 @AaronGoodman33 @hemepathguy #Pathology #PathTwitter

Here are some IHC features

Ceruminous adenoma of external acoustic canal in a 67 yo patient! Some of the histological clues are: - Well circumscribed - Apocrine features - Brownish ceruminous pigment @JMGardnerMD @DrGeeONE @TristanRutland7 #pathology #headandneck #pathtwitter

@sumeyra_md @yro854 @Histopatolomon @pembeoltulu @JMGardnerMD @smlungpathguy @dreylulgun @atman_ci Given their basophilia, cristalline structure and the fact that the material was not washed away during processing, I would be more oriented on some sort of mineral origin. Btw was the pt taking any specific medicament?

I had never noticed these crystalloid formations in the gallbladder surrounded by bile.I like these images under polarized light. But I have no idea what they are. What do you think? #PathTwitter I couldn't find anything like that in any book or your foreign body atlas. @yro854
