ABSTRACT
Primary liposarcoma of the lung is an exceedingly rare phenomenon, with fewer than ten cases reported in prior literature as of 2024. Rarer still, dedifferentiated liposarcoma of pulmonary origin is even less frequently reported, with only two cases having been described. Here, we detail the case of a 66-year-old female who presented with a large left-sided obstructing lung mass and underwent bronchoscopy with tumor cryoprobe debulking. Histological examination revealed a spindle cell sarcoma corresponding to a dedifferentiated liposarcoma with leiomyosarcomatous features as murine double minute 2 translocation was identified by fluorescence in situ hybridization and desmin by immunohistochemistry. The patient completed multiple radiotherapy sessions followed by pneumonectomy and a relatively uncomplicated postoperative course. As pulmonary liposarcoma tends to be poorly responsive to typical chemotherapy, standard management of pulmonary liposarcoma in the absence of metastases is surgical intervention to improve patient survival. Thus, we maintain that pulmonologists, oncologists, and radiologists should have a heightened awareness of this unique pathology in patients presenting with solitary lung mass.
