Report of the first case of myxoid liposarcoma in Colombia: a rare tumor

Introduction: Primary esophageal myxoid liposarcoma is exceedingly rare. Sarcomas make up 1% of esophageal malignant tumors. There are only five (5) cases reported with this histological variant (myxoid) in previous literature. In Colombia, this is the first case reported and the sixth in the world. Objective: To report the first case in Colombia of myxoid liposarcoma of the esophagus with clinical, radiographic images, histology, surgical and to describe difficulties in the diagnosis. Methodology: We reviewed the clinical history of a 28-year old male patient. He was admitted to Hospital Universitario del Valle in Cali, Colombia with a clinical history of dysphagia, weight loss, and excessive salivation. The initial examination (esophagogram, cervical CAT scan and endoscopy) demonstrated a mass that was reported as a fibrovascular polyp. The finding of the pathological diagnosis was myxoid liposarcoma. Conclusions: The rarity of this condition recommends report of its detailed description. The myxoid liposarcoma of the esophagus can be diagnosed if a patient has a history of a slow-growing esophageal mass with a low tumor density in computed tomography in combination with surgical resection and histological examination.
