title: [A Case of Spindle Cell Lipoma in the Inguinal Region].
abstract: A 68-year-old man presented to our hospital for the first time because of a left inguinal mass that had been gradually enlarging over the past 20 years. At the initial visit, a 10×5 cm, soft, movable mass was detected in the left inguinal region. Magnetic resonance imaging revealed a smoothly shaped, internally heterogeneous tumor, with suppressed areas on a fat-suppressed image. In addition, the tumor showed partial enhancement with gadolinium and it did not continue into the spermatic cord. We performed excision of mass. During surgery, we observed that the tumor was well circumscribed and located on an aponeurosis of the external abdominal oblique muscle; therefore, we inferred it occurred from the subcutaneous tissue. The excised tumor was smoothly shaped and contained yellow and white nodes. On histopathological examination, the tumor was identified as a spindle cell lipoma.
