A-59-year-old man who was seen at the hospital because of swelling of the left inguinal region was found to have a left dilated inguinal canal and a 2-cm diameter low density mass at the same area by abdominal CT scanning. Left inguinal hernia with a lipoma was diagnosed and he was operated on under lumber anesthesia. During surgery a hernia sac with the size of the tip of the little finger was found in the spermatic cord and it was dissected. Further an elastic-soft and yellow-colored tumor with the size of the tip of the thumb was detected in the center of the spermatic cord. It was removed. The removed specimen had smooth surface and was elastic-soft and yellow in color. The histopathology revealed fat cells and interstitial component, and floret type giant cells and rope-like collagen fiver bundle were identified in the interstitial part. Immunohistochemistry of the tumor cells were CD34 positive and S-100 negative. From these findings, pleomorphic lipoma was diagnosed. This tumor often affects the back of the neck, shoulders, or back of men in their forties to seventies. This paper describes our case of a pleomorphic lipoma in the spermatic cord.
