💥Papillary craniopharyngioma 💥Unusual papillary PitNET 💥Posterior pituitary tumor (pituicytoma family) 💥Papillary ependymoma

This sort of papillary looking PitNET is common with gonadotropic adenoma

Agree PitNET. Perivascular-like pseudo rosettes really are not that specific to ependymoma, unlike true ependymal rosettes.

Pituitary adenoma/PitNET

Can AI identify PitNET lineage from routine H&E slides alone? An attention-guided neural network achieved high scores and uncovered lineage-specific morphologic patterns, highlighting the potential of AI to support pituitary tumor classification. link.springer.com/article/10…

Clinical and Pathological Spectrum of Acromegaly: Distinguishing GH PitNETs, Mammosomatotrophs, and Mixed Tumors * Estos hallazgos resaltan la heterogeneidad dentro de los PitNET GH&PRL, incluidos los PitNET GH PRL-positivos silentes. Nuestros datos sugieren que los tumores SL mixtos pueden ser menos sensibles a los ligandos SSTR, lo que enfatiza la necesidad de estrategias personalizadas basadas en el subtipo tumoral y el perfil del receptor. f.mtr.cool/aublrpflva @NeuroendocrinoS

A study in Endocrine Pathology introduces an attention-guided graph neural network to predict PitNET lineage from H&E-stained whole-slide images. The model achieved a mean F1-score of 92.78% in internal validation, indicating strong performance. bit.ly/4uQiV2f

Como si no fuera suficiente con los ginecólogos que tratan hipotiroidismo en el embarazo y diabetes gestacional, ahora también un ginecólogo que trata PitNET productores de prolactina, ¿Qué sigue?

Incrustado en lo profundo de craneofaringiomas, tumores neuroendocrinos hipofisarios (PitNET), meningiomas y gliomas. El virus no solo pasó de largo, colonizó. Permanece en las células tumorales y en las delicadas membranas endoteliales que protegen la barrera hematoencefálica.

endo saw my pitnet on mri and said we can wait until i want to have kids ??? like

@AmerMedicalAssn @PresAmerMed @PatientAction @patientaccess @ACSCAN Oncologist seen -3 Endocrinologists seen - 3 Neurosurgeons seen - 2 I have self diagnosed myself with a "rare gonadotroph pituitary microadenoma with more than one hormone involved." I want this documented because of all the doctors I have seen in 4 years and more have dismissed me with either having a cyst or menopause. The treatment of me has been disgusting. I have declined physically. I even told them that. I know my diagnosis is correct, and there have only been 4 to 5 cases reported. As I said, I want this documented, so I am putting it here. When I get a doctor on board and we can finally get my pituitary tumor out of my brain and the Havoc it is causing on my body and has caused, I will post the results of pathology and exactly what it was. Because I guarantee it is exactly what I'm saying it is. Once I am through all of this, I will be pushing for a change. You can not call yourself one of the top cancer centers, and believe me, I went to a few, and tell me what you have told me. That this is a cyst and just menopause. Some of them I got to admit it is a pituitary adenoma but had to prove it again and again even after. I have told the doctors what to look at. It is all right in front of them. The last doctor I saw I told him what it was. A "PitNET". He responded quickly, "No, it's not." I responded right back "yes it is, " and explained why. I told the "neuroendocrine" Dr. what tests to compare as I was leaving the appointment. If you order a test, look at it, look at the other tests that have been ordered by other doctors, compare them, put the diagnosis together like a puzzle like I had to without going to medical school. I should not have to go through this battle with the top doctors and top cancer places in America. No one should. @AmerMedicalAssn #NeuroendocrineTumorAwareness #MEN1 #PitNET #pituitaryadenoma

Nice CAM5.2 positive fibrous bodies in a sparsely granulated somatotroph PitNet

New article out now #AIMMhighlights 🔵 T-PIT & PIT-1: 0/223 non-PitNET H&N tumors — 100% specific for corticotroph and somatotroph PitNET 🔵 SF-1: 7/214 positive (rare SCC; 25% SMARCB1-def sinonasal ca; 20% NUT ca) — still useful for gonadotroph PitNET (~3.3% off-target)

A good example of a microscopic PitNET (previously pituitary microadenoma). Pt had symptoms of Cushing’s disease. Note the tumor (blue) and adjacent ant. Pituitary (green). Stains for T-PIT and ACTH are provided. #pathx #pathtwitter #neuropath #neuropathology #cnspathology

【脳腫瘍の同定】 「年齢」と「場所」が重要でこれでほぼ決まります。 例えば「類円形細胞」が出たら ❶小児＋小脳虫部 👉髄芽腫 ❷小児＋脳室 👉上衣腫 ❸成人＋前頭葉 👉乏突起膠腫 ❹成人＋下垂体/トルコ鞍 👉下垂体神経内分泌腫瘍（PitNET） ※特徴的な臨床所見の記載がない場合もあります
