Definition

Liposarcomas may occur either in the anterior or the posterior mediastinum (Hahn and Fletcher 2007; Klimstra et al. 1995; Ortega et al. 2014).

Presenting symptoms are related to compression exerted by a tumor on the adjacent anatomic structures; they include shortness of breath as well as cough or palpitation. However about one third of cases are discovered incidentally. Like lipomas, liposarcomas have also been described in obese patients with systemic lipomatosis.

Clinical Features
