ABSTRACT

Esophageal dissection is a rare condition, characterized by disruption of the submucosa from the muscular layer of the esophageal wall. It is commonly iatrogenic in etiology and patients typically present with acute onset dysphagia, odynophagia, and retrosternal pain. The condition can be diagnosed endoscopically; however, contrast swallow studies either with CT or fluoroscopy carry less risk and are the imaging investigations of choice for this condition. Patients are managed conservatively in the majority of cases. In this case report, we present a case of chronic esophageal dissection in a 15-year-old male who had undergone endoscopic removal of a foreign body from the esophagus several years prior. We discuss the clinical features, radiological diagnosis, and management of this condition.

ABSTRACT

With recent advances in molecular research, an ever-increasing number of undifferentiated round cell sarcomas without the characteristic gene fusions of Ewing sarcoma are being discovered. One specific subtype termed BCOR-rearranged sarcoma belongs to this group. Previously termed 'Ewing-like' sarcoma, it was formally included with undifferentiated round cell tumours in the 2013 WHO Classification of Soft Tissue and Bone Tumours. However, in the 2020 WHO Classification, BCOR-sarcoma is now recognized as a distinct entity due to particular morphological and immunohistochemical features and differing clinical outcomes. As with classical Ewing sarcoma, osseous BCOR-rearranged sarcoma is an aggressive tumour with a similar clinical presentation. However, there are only a small handful of case series and isolated reports detailing the imaging characteristics, typically demonstrating an aggressive bone lesion with a large soft tissue mass. Soft tissue BCOR-sarcoma is even rarer. The aim of the current review is to describe the patient demographics, lesion locations and various imaging characteristics of histologically proven cases of musculoskeletal bone and soft tissue BCOR-sarcoma as described in the literature.
