A Case of the Spermatic Cord Liposarcoma which Appeared after Resection of a Spermatic Cord Lipoma

Abstract

A 68-year-old man visited our hospital with a bulge in the right inguinal region. We diagnosed right inguinal hernia and performed laparoscopic operation under the general anesthesia in October 2015. However, we were unable to find the hernia sac, changed the diagnosis to a right inguinal region mass, and performed resection of the mass. Histopathology of the resected mass revealed the diagnosis of lipoma of the right spermatic cord. Subsequently, the patient visited us again with a bulge in the right inguinal region in February 2017. We diagnosed the bulge as a recurrence of lipoma of the right spermatic cord and performed mass resection under the spinal anesthesia in March 2017. However, histopathology at this time revealed the diagnosis of liposarcoma of the right spermatic cord. Thereafter, we have been following up the patient semiannually, and until now, two and a half years after the surgery, there has been no evidence of recurrence. We report a rare case of liposarcoma of the spermatic cord which appeared after resection of lipoma of the spermatic cord.
