- Sclerosing epithelioid fibrosarcoma (SEF) is a rare type of cancer characterized by specific cell arrangements and unique traits, including a distinct immunohistochemical pattern and gene rearrangements involving EWSR1 and CREB3L genes.
- Although typically found in deep soft tissues, SEF can also occur in bones and other organs; however, this report highlights a rare case of SEF originating in the brain, specifically the left occipital region.
- The study discusses the necessary differential diagnoses for brain tumors and provides a detailed genetic and epigenetic comparison of this brain tumor to more common systemic cases of SEF.
Background And Aims: Alveolar soft part sarcoma (ASPS) is an ultra-rare chemo-resistant sarcoma in children, occurring preferentially in young adults. We aimed to describe and compare its clinical presentation and behaviour in children and young adults to determine whether the same therapeutic strategy should be addressed for both populations.
Methods: National retrospective multicentre study of children (0-18 years) vs.
