title: [A case of myxoid liposarcoma in the right inguinal region: a case report].
abstract: We report a case of myxoid liposarcoma developed in the right inguinal region. A 45-year-old man visited our hospital with a chief complaint of painless right inguinal mass. He was diagnosed with right direct inguinal hernia for the first time and received a hernia repair. However, the size of the inguinal mass increased gradually after the operation. Then, the tumor was re-evaluated by imaging study such as ultrasonography, computed tomography and magnetic resonance imaging. A fatty mass 4.0 cm in diameter was demonstrated and the tumor was diagnosed as a liposarcoma preoperatively. In addition to the right high orchiectomy, surrounding fatty tissue was also removed at the time of the operation. Histological examination revealed a myxoid liposarcoma and the existence of several daughter regions outside the pseudo-capsule. Right spermatic cord and testis were intact. Postoperatively, he received 54 Gy dose of radiation therapy to right inguinal region for the prevention of the local recurrence of the disease.
