nice case with informative comments.

I love the continous updates

Thanks very much to the Path Ways team. This case discussion on sinonasal sarcoma was very helpful, especially your clarity on the differential diagnosis & Immunohistochemical markers. Practicing pathologists are immensely benefited as low grade sarcomas are diagnostically challenging.
Please publish more case studies & your unique insight on low grade sarcomas especially abdominal & pelvic regions also.

Very informative differential diagnosis. Please publish a case study on Pediatric low grade gliomas and/or other brain tumor pathology

Interesting case and good concise discussion. Thank you.

very informative and didactic pathological cases, a nice way to do CME/CPD
