◇ Esophageal liposarcoma
Introduction
- esophageal liposarcoma : extremely rare tumor
- males, middle aged individuals
: wide range of age distribution d/t slow growth
Clinical presentation
- preponderance upper esophagus
- dysphagia: m/c initial symptom
- all patients need long-term follow up
; can recur many decades
Radiologic findings
- pedunculated, well circumscribed, well differentiated
 safely resected locally

17. Liposarcoma arise from fibrovascular polyp
Mimic Giant Fibrovascular polyp
; can arise in GFVP
Liposarcoma : local recurrence are common
may metastasize
 rare but should be considered in large esophageal mass
