@drruizcor Buen dia doc, las clases se graban?

Inscríbanse! No se van a arrepentir

Quiero compartir nuestro artículo publicado en revista de la ACHO acerca de la biología molecular de cancer colorectal. Un enfoque práctico de vías moleculares biomarcación y biopsia líquida. @carlosbon78 @AndresFCardonaZ @CxSguerrero revista.acho.info/index.php/acho…

Implant associated ALCL of the breast. Hallmark cells, characterized by their eccentric, horseshoe- or kidney-shaped nuclei and abundant cytoplasm, are illustrated in the provided pictures, along with their CD30 positivity.

Case of the day: Middle-aged man with recent history of resection for primary lung squamous cell carcinoma, currently receiving chemotherapy, who presents for follow-up bronchoscopy showing 2 polypoid endotracheal/endobronchial lesions in the carina and lingula. Given the history, are you concerned for squamous cell carcinoma? #lung #Moffitt #pathology #path #pulmpath #thoracicpath #MedEd @USFpathology

Frozen section of paratesticular mass. Characteristic features include dilated channels simulating vessels and prominent smooth muscle stroma and cells with cytoplasmic vacuoles. Right FS diagnosis saves the testis. #gupath #urology

@FridaRosenblum Oh my gosh, excelent hahahah, really

I work out so when the fellow says “do you need help with that?”, I can confidently reply “no, I got this!”

I am thankful for the privilege of teaching the next generation of pathologists at @MoffittNews. We are still looking to fill Moffitt’s Thoracic Pathology fellowship. Check us out #MedEd #lungpath #pathologyfellowship #fellowship #thoracic @NushaniMD moffitt.org/education/medi…

In thoracic pathology, metastases are frequently encountered. It is essential to be familiar and comfortable with interpreting immunostains in lung tumors. Breast carcinomas often express neuroendocrine markers without being neuroendocrine tumors (e.g., large cell neuroendocrine carcinoma). A lung biopsy showing carcinoma strongly positive for neuroendocrine markers is not necessarily a primary or metastatic neuroendocrine carcinoma, especially with a history of breast cancer. The case below illustrates this point. Always fully work up malignant lung biopsies, particularly with a history of malignancy. This tumor was also ER- and PR-positive, consistent with the clinical history (invasive breast carcinomas with neuroendocrine features are often ER- and PR-positive and HER2-negative, but I am not a breast pathologist!). Many other tumors also express neuroendocrine markers without being neuroendocrine neoplasms. @MoffittCancerCenter @USFHealthPathology #lung #pathology #PathTwitter #pulmpath #thoracicpath #cancer #breastcancer

Gastric neuroendocrine tumors-Previous post corrected Size cutoff: Lesions <0.5 mm are often considered tumorlets or precursor lesions, while those ≥0.5 mm are classified as neuroendocrine tumors (approximately 1 high-power field). In the context of autoimmune atrophic gastritis, these tumors are generally indolent. Dr. Panarelli - 2025 Diagnostic Pathology Update #pathology #PathX #PathTwitter

Cervix - Circumferential tumors - Measure them prior to opening. - Measure maximum tumor diameter (see left picture). - Measuring after opening the cervix and adding segments linearly would overestimate tumor size. - This rule applies to tumors that are grossly visible and not visible.

This pancreatic needle biopsy show pancreatic ductal adenocarcinoma (arrows) and is easy to diagnose on H&E. For more subtle cases, nuclear loss of DPC4/SMAD4 can be confirmatory, as described in over 25 years ago. Wilentz RE, et al. PMID: 10623651

Do we have to grade medullary thyroid carcinomas? Yes. If there is tumor necrosis, ≥5 mitoses per 2 mm², or ≥5% Ki-67 labeling index, classify the tumor as high-grade MTC. What constitutes necrosis? See pic 2 Dr. Nishino - 2025 Diagnostic Pathology Update #USCAP #pathology #PathX #PathTwitter

Do we grade thyroid cancer? Yes. Poorly differentiated carcinomas: Histologically poorly differentiated tumor with solid, trabecular, or insular pattern of growth with - Convoluted nuclei, or - ≥3 mitoses per 2 mm², or - Tumor necrosis If you have solid, trabecular, or insular pattern of growth and nuclear atypia of PTC, you call these PTC, solid subtype. If these have ≥5 mitoses per mm² or necrosis, you call them high-grade differentiated carcinoma. Dr. Nishino - 2025 Diagnostic Pathology Update #USCAP #pathology #PathX

@KirillLyapichev @PathologyRWJMS @Mehrnazmvs @UTMB_Pathology @MdSuster @Rutgers_NJMS @rutgershealth @RutgersU @CLEClinicLabs @CCFPathRes Thank you so much Dr. God bless you 🙏

Honored visiting the Pathology Dept at Rutgers @PathologyRWJMS for Grand Rounds & an engaging case slide session! Great chats with faculty, inspiring residents (@arturo_cano1 @Mehrnazmvs), and so proud to see my former @UTMB_Pathology trainee now as a full attending Dr. Iqbal!
