Dedifferentiated Liposarcoma in a Giant Esophageal Polyp: A Case Report and Review of the Literature

Malav P Parikh et al. Cureus.

Abstract

Soft tissue sarcomas represent an extremely rare cause of esophageal masses, and undifferentiated sarcomas are rarer. The proportion of dedifferentiated liposarcomas (DDL) is even lower. The case of a 58-year-old male who complained of dysphagia and was found to have an 18-centimeter long esophageal mass/polyp on esophagogastroduodenoscopy is presented. The lesion was resected endoscopically and a diagnosis of DDL was confirmed by fluorescence in situ hybridization. Due to its rarity, the treatment experience with esophageal DDLs is limited. However, based on our experience, endoscopic resection of the lesion can be considered as the treatment of choice when feasible. We performed a review of the literature to identify and analyze similar reported cases.

Keywords: endoscopic release; esophageal cancer; fluorescence in situ hybridization; liposarcoma; neoplasia.
