For trainees->nice exp of collagen ball in a pelvic wash sample. Not to be confused with adenoca (which may be seen as 3D structures w community borders). Collagen balls r seen in up to half of pelvic washings & r spherical masses of collagen lined by mesothelial cells
#CytoPath
Some follicular lymphomas may appear to be BCL2-negative with commonly used IHC antibodies. Some of these cases have mutations in BCL2 that impact protein detection. Alternate BCL2 clones may be useful, as in this case.

Oh Boy! This is a stunner. Pancreatic tumor. Youngish person. Diffusely keratin positive. Was called a poorly differentiated carcinoma. Sounds reasonable? #GIpath
Andrew H. Fischer, MD, candidate for ASC Executive Board Medical Member answers the question, What do you see happening in your current work environment that may have an effect on the cytopathology community? buff.ly/3bmX5fi
Appendix with lupus vasculitis. Appendectomy for presumed appendicitis. No acute appendicitis seen. Vessels within and outside of the appendix showed these changes with focal fibrinoid necrosis. Clinically and serologically active SLE. #GIpath#pathology
CAP (@Pathologists) is launching Virtual Live Lectures for pathology residents! Join us every weekday at 10am CT for expert lectures. Series kicks off tomorrow, 4/1, w/ @bjmagnani titled "Tik Tox". Learn more: capatholo.gy/virtual-lecture…#pathresidency
Kudos to all the Path educators, who are continuing teaching in these uncertain times! What do you think these beautiful (hint: rosette-like) organisms are? #microbiology#pathology
Senior residents:
Myself and others serve on @TheABPath Resident and Fellow Advisory Committee. We will be discussing the current situation on Thursday directly with Dr. Johnson.
DM me your concerns and I will anonymously communicate them on the call. #pathboards
As residency programs begin to adopt #RemoteLearning initiatives, we hope you will find our digital slide repository valuable. Hundreds of annotated cases across a wide range of diagnostic entities: learn.mghpathology.org/index…
Biopsy of an incidentally discovered 5 cm well-circumscribed retroperitoneal mass abutting the bladder in a middle aged adult. Does anyone want to hazard a guess before I show the IHC? #BSTpath#pathology
Good thoughts! B is Wilms tumor (mutation of WT1, CTNNB1, or AMER1) and C is retinoblastoma (RB1 or MYCN mutations).
☝️A is still pending correct answer... This is an infratentorial tumor. Any ideas?
CRYSTAL STORING HISTIOCYTOSIS in a lymph node. Macrophages laden with eosinophilic subtle crystalline material. CD68 and kappa IHC shown. Lambda was negative. #pathology#hemepath#BSTpath
