Biphasic SS doesn't get better than this. IHC: AE1/AE3

Nice review article by Szczepanski, Westerhoff and Schechter on this rare entity (pubmed.ncbi.nlm.nih.gov/39743931/)

The spindled morphology and plexiform architecture can sometimes cause these tumors to be mistaken for (SDH-deficient) GIST. Unlike GIST, these tumors are negative for CD117 and DOG1.

It’s gastric and spindled, but it’s not a GIST… Plexiform fibromyxoma is a benign tumor that presents as a multinodular intramural mass in the stomach. The nodules can be fibrous or myxoid and have a delicate capillary pattern. #BSTPath, #UmichPath, #BSTpathGoBlue

Over the past several years, we have seen several examples and now you can read about our experiences with these patients and the pathology of these unusual tophi. journals.lww.com/ajsp/abstract/… #bstpath #gout #pseudogout

@Raficano_andres Yes there was desmin and cd34 staining

@KyleDPerryMD Does this case desmin +?

Dealing with an unusual fibromyxoid spindle cell neoplasm (that is MUC4 negative)? Consider PLAG1! #BSTPath, #UmichPath, #BSTpathGoBlue

Special thanks to colleague at U of Michigan for allowing me to share this case!

Some nice papers (Fritchie and colleagues/ Chung and colleagues) further elaborating on this entity(ies)…. pubmed.ncbi.nlm.nih.gov/33097826/ pubmed.ncbi.nlm.nih.gov/33300192/

I would highly recommend this course for anyone (regardless of level of expertise) looking for a comprehensive/case-based experience with bone and soft tissue. Dr. Fritchie and colleagues at Cleveland Clinic are excellent teachers. clevelandclinicmeded.com/live/courses/c…

Nice article on ALK-positive histiocytosis of the breast: pubmed.ncbi.nlm.nih.gov/32826530/

Interestingly, the cells in this case also showed staining for OCT2, which has historically been associated with other histiocytic-type proliferations, such as Rosai-Dorfman disease, some Langerhans cell histiocytosis, and juvenile xanthogranulomas.

ALK-positive histiocytosis of the breast is a rare tumor that can mimic other inflammatory neoplasms or processes, such as inflammatory myofibroblastic tumor, cellular spindled histiocytic pseudotumor (among others). #BSTPath, #UmichPath, #BSTpathGoBlue
