[A Case of Isolated Metachronous Splenic Metastasis after Rectal Cancer Surgery].

A 50-year-old woman underwent laparotomic anterior resection(D3)and total hysterectomy with bilateral adnexectomy (type 2, 3.0×4.5 cm, pT4a[SE], N1a, M1c2[ovary and peritoneum], H0, P1, PUL0, stage Ⅳc, tub2>por, Cur B)for ovarian metastasis from rectal cancer in June 20XX. During the outpatient visit in May, 2 years and 11 months after surgery, a splenic tumor was found on abdominal contrast-enhanced CT, without distant metastasis in other organs. In July 20XX, laparoscopic splenectomy was performed for suspected splenic metastasis of rectal cancer. The specimen of the resected tumor showed pathological findings consistent with metastasis of rectal cancer. Currently, the patient is being followed up without any sign of recurrence. Herein, we report a rare case of isolated metachronous splenic metastasis, whose associated prognosis might be improved by surgical treatment, in reference to the literature.
