We have ready to use our #FioNA. Very excited that medical students can make their Pathology practices more and more realistic. Thanks her father @edusqo. Thanks the boss @recio_vicioso who sponsors her in the U.M.A. And @isi200x enjoy yourself teaching. @SEAP_IAP
PSEUDOMYOGENIC HAEMANGIOENDOTHELIOMA. NGS: ACTB-FOSB. NB: plump epithelioid cells with occasional cytoplasmic inclusions; ovoid nuclei with small nucleoli; focal stippled calcification; this genetic variant more often unifocal than SERPINE1-FOSB (PMID: 30256258, 30459475).
Breast carcinomas are classified as pT4b if they have:
💥Skin ulceration (usually grossly recognized)
☄️Ipsilateral satellite skin nodules (tumor within dermis,separated from main mass)
🌬Inflammatory carcinoma
#breastpath#pathology#pathboards#pT4b
of the 4 current 8th AJCC ways to get pT3a in RCC staging (renal vein invasion, sinus fat invasion, perinephric fat invasion, pelvicalyceal system invasion),
I find that PERINEPHRIC FAT INVASION as shown here is in uncommon way to get to pT3a!

Colonic glands in prostate biopsy can mimic prostate cancer, specially if they are dysplastic. Key is to recognize the presence of lamina propria and not to misinterpret a PIN4 stain. #GUpath
DEDIFFERENTIATED LIPOSARCOMA WITH MENINGOTHELIAL-LIKE WHORLS AND METAPLASTIC BONE FORMATION. IHC: MDM2. NB: rare subtype that occurs more often in retroperitoneum; bone may be metaplastic or osteosarcomatous; whorls may occur in association with vessels (PMID: 21317707).
#caseoftheday 37 yo👨🏻 with lymph node biopsy. 🔬: granulomatous lymphadenopathy suggestive of sarcoidosis. Well formed granulomas without central necrosis and asteroid bodies (intracellular starshaped crystalline inclusions) #hemepath#pathology
