[Local recurrence of liposarcoma of the spermatic cord 6 years after orchiectomy: a case report].

A 78-year-old man had undergone high inguinal orchiectomy because of a tumor of the right spermatic cord. Pathological diagnosis was pleomorphic liposarcoma according to the WHO classification. Adjuvant therapy was not performed because of advanced age. Six years later, he consulted our hospital with the chief complaint of asymptomatic swelling of the right scrotal region. Local recurrence was suspected, and tumorectomy was performed. Pathological diagnosis was pleomorphic liposarcoma with cartilaginous metaplasia. A review of 6 cases of recurrent intrascrotal liposarcoma reported in Japan, including the present case, revealed that 5 cases recurred locally in the same lesion and were growing slowly. Therefore, we considered that intrascrotal liposarcoma should be resected as extensively as possible and observed for a long period.
