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

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.

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.

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

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/liv…

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

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.

Cellular spindled histiocytic pseudotumor (often of the breast) can sometimes be confused for inflammatory myofibroblastic tumor. The spindled cells exhibit irregular grooved nuclei which help suggest the tumor’s histiocytic nature. #BSTPath, #UmichPath, #BSTpathGoBlue

Although not typically associated with a “round cell sarcoma” differential, solitary fibrous tumor can sometimes mimic small round cell type sarcomas such as Ewing sarcoma. #BSTPath, #UmichPath, #BSTpathGoBlue
