Primary lipoma of the diaphragm

Abstract

Lipoma of the diaphragm is an extremely rare entity. The patient described was a 43-year-old woman, who was admitted to our hospital with an abnormal shadow on her chest CT scan. The preoperative diagnosis was a strongly suspected lipoma of the diaphragm, but the possibility of highly differentiated liposarcoma could not be ruled out. The primary tumor, measuring 6.5×3.6×2.9 cm, located above the left hemidiaphragm, was resected, and a final diagnosis of spindle cell lipoma originating in the diaphragm was made.
