Invasive ductal carcinoma is a rare but subtle finding when associated with architectural distortion.👇 thepathprincess.substack.com/p/invasive-duc… Don't miss the angulated invasive glands! #pathology #pathologists #breastpathology #PathTwitter #PathX #breastpath

Leafy clefts of benign phyllodes tumor can be eye candy. #pathology #breastpath #benign_phyllodes

Not your average architectural distortion! Ductal carcinoma in situ can present this way, though more commonly with calcifications. thepathprincess.substack.com/p/ductal-carci… A reminder that classic presentations aren't the only ones!💡 #pathology #pathologist #breastpath #pathtwitter #pathX

No doubt—you all crushed it! 💯 The answer: B-cell lymphoma. This one’s a marginal zone lymphoma of the breast—rare, and a great mimicker of lobular carcinoma. Hope this was a helpful review of the lobular carcinoma differential! #PathX #PathTwitter #breastpath #PathQuiz

Let’s review the tricky differential of low-grade spindle cell lesions of the breast this week! Case of Pseudoangiomatous Stromal Hyperplasia (PASH) 🔬 Usually mimicking vessels, PASH can also appear fascicular. #PathX #PathTwitter #breastpath

Breast, retroareolar mass, 30y #pathology #patologia #breastpath #breastpathology

Case of Myofibroblastoma 🔬 A benign spindle cell tumor that loves collagen bundles (and often shows up in male breasts). CD34, desmin, and ER light it up. #PathX #PathTwitter #breastpath

Case of Cellular Spindled Histiocytic Pseudotumor 🔬 A reactive spindle cell lesion of histiocytes — likely the exuberant end of fat necrosis — saddled with a name longer than the lesion itself. #PathX #PathTwitter #breastpath

Architectural distortion caused by fat necrosis. An example of how benign processes can mimic malignancy. thepathprincess.substack.com/p/fat-necrosis… Always consider the patient's clinical history alongside the microscopic findings. 📷 #pathology #pathologist #pathX #pathtwitter #breastpath

Case of Nodular Fasciitis of the Breast 🔬 Fast-growing, mitotically active, and a classic diagnostic trap. Despite the drama, it typically regresses on its own. #PathX #PathTwitter #breastpath

Hello Friends! I'm writing to invite you to our 1st AIMM Journal Club-live on Microsoft Teams this Thursday, August 28th @ 7 pm EST. We've invited the authors of 2 recent great papers to present. Katrina Collins, MD || Pathologist & I will moderate attendee Q&A. Register here: tinyurl.com/ycxeye84

Crushed it! 🎯 The answer: adenomyoepithelioma (AME). AME can sometimes take on a more spindled morphology, as in this case. Shown here: SMA immunohistochemistry 👇 #PathX #PathTwitter #breastpath #PathQuiz

Let’s continue to review low-grade spindle cell lesions of breast this week! Case of Neurofibroma of Breast 🔬 Benign spindle cell lesion with wavy nuclei and collagen bundles—a reminder that not all breast spindle cell lesions are metaplastic. #PathX #PathTwitter #breastpath

Case of Schwannoma of Breast 🔬 A little Antoni A, a little Antoni B, and some Verocay bodies—a textbook nerve sheath tumor in an uncommon site. #PathX #PathTwitter #breastpath

Intraductal papilloma can present as architectural distortion (AD) on imaging thepathprincess.substack.com/p/intraductal-… Associated sclerosis can contribute to the AD appearance.📷📷 #pathology #pathologist #breastpath #pathX #pathTwitter

Case of Spindle Cell Lipoma of Breast 🔬 Mix of fat, collagen, and bland spindle cells—a soft tissue classic that’s rare in the breast. #PathX #PathTwitter #breastpath
