[Two Cases of Splenic Tumors Safely Resected by Hand-Assisted Laparoscopic Splenectomy].

Case 1: The patient was an 80-year-old woman with a history of chemoradiotherapy for cervical cancer 4 years ago. Splenic tumor was detected on contrast CT. On PET-CT showed accumulation of FDG in the splenic tumor. The tumor size increased over time, and a hand-assisted laparoscopic splenectomy(HALS)was performed. Pathological findings were consistent with splenic metastasis from cervical cancer. Case 2: The patient was a 64-year-old woman who had undergone partial mastectomy for right breast cancer 14 years ago. A splenic tumor was detected on an abdominal ultrasound performed for non-alcoholic steatohepatitis. Contrast CT revealed progressively increasing contrast enhancement. PET-CT showed accumulation of FDG in the tumor. Although sclerosing angiomatoid nodular transformation(SANT)was considered first, HALS was opted for due to the possibility of malignancy. The pathological examination confirmed the diagnosis of SANT. Splenic tumors are rare, and preoperative diagnosis is generally difficult. HALS is a less invasive surgical approach compared to laparotomy and appears to be safe and suitable for splenectomy in patients with splenic tumor.
