We report a fortuitous discovery of primary pulmonary myxoid liposarcoma in
an HIV-positive patient.
Primary pulmonary localizations are uncommon. Generally, pulmonary localiza
tions are metastatic. There is a male predominance and diagnosis is general
ly made around 40 years of age.
The two main features of liposarcoma are the large tumor size and the compl
ex histology that evolves over time. Pathologist findings are rarely reprod
ucible and vary from one pathologist to another.
Macroscopically liposarcomas can mimic benign tumors. The risk elf recurren
ce is high after simple enucleation due to microscopic extracapsular extens
ions.
Surgery remains the predominant treatment. Wide complete excision, if possi
ble, provides long-term survival.
