Leiomyosarcoma after Total Laparoscopic Hysterectomy with Power Morcellation.

INTRODUCTION: Power morcellation is an effective and minimally invasive technique used to remove specimen tissues or the uterus in total laparoscopic hysterectomy (TLH). However, it has the risk of intraperitoneal dissemination of tissue and can cause a parasitic myoma. We report a case of leiomyosarcoma that occurred 4 years after TLH with power morcellation for fibroids. CASE: A 52-year-old woman was referred to our hospital with a pelvic mass. She was diagnosed to have submucosal fibroids and had undergone TLH with power morcellation 4 years previously. The uterus weighed 398 g at that time. At present, a parasitic myoma was suspected, owing to the diagnosis of fibroids on the initial pathological evaluation. She underwent laparotomy, and the tumor was removed. Although the pathological evaluation confirmed the tumor to be a leiomyosarcoma, a review of the initial tissue did not show the presence of any malignancy. Since there was no metastasis, she was followed-up without additional treatment. CONCLUSION: Even if the initial pathologic evaluation suggests a benign mass, parasitic myoma and even sarcoma can occur after TLH with power morcellation. Considering the risk of dissemination and occult malignancy, the use of power morcellation should be avoided if there are alternative options to remove the tumor.

Solitary uterine metastasis of invasive lobular carcinoma after adjuvant endocrine therapy: a case report.

INTRODUCTION: Solitary uterine metastases from extragenital cancers are very rare. Breast cancer is the most frequent primary site of metastasis to the uterine corpus, with invasive lobular carcinoma more likely to spread to gynecologic organs than invasive ductal carcinoma. CASE PRESENTATION: A 62-year-old postmenopausal Japanese woman was diagnosed with uterine leiomyomata more than 20 years ago and had been managed conservatively until menopause. Seven years prior to her presentation, she was diagnosed with breast cancer and underwent a partial resection of her right breast for stage IIA invasive lobular carcinoma. She underwent adjuvant chemotherapy, radiotherapy, and five years of anastrozole hormonal therapy. She presented with a growing uterine mass. Her tumor marker levels were markedly increased over the course of her follow-up, but a systemic examination revealed only a solitary uterine tumor. She underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. A histopathological examination, including detailed immunohistochemistry, confirmed metastatic invasive lobular carcinoma, infiltrating both her uterine myometrium and fibroid tissue. CONCLUSION: We report a very rare metastatic pattern of invasive lobular carcinoma and demonstrate that gross cystic disease fluid protein-15 and mammaglobin are useful in the diagnosis of metastatic breast cancer.

A novel therapeutic strategy for chylous ascites after gynecological cancer surgery: a continuous low-pressure drainage system.

PURPOSE: Postoperative chylous ascites is an unusual complication following retroperitoneal surgery. A search of the English literature showed only 44 cases of chylous ascites following gynecological cancer surgery. The treatment is primarily conservative, but surgical treatment is considered in resistant cases. We developed a novel non-surgical therapeutic strategy for postoperative chylous ascites. METHODS: We report a case of severe chylous ascites following pelvic lymph node dissection for gynecological cancer. RESULTS: Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal washing, and systematic pelvic lymph node dissection were performed for a stage II G1 endometrioid adenocarcinoma (FIGO 2009). Forty-one days after surgery, the patient was readmitted due to massive ascites. Repeated paracentesis and a low-fat diet were only partially effective. Fifty-one days after surgery, we started paracentesis with a continuous low-pressure drainage system. Nine days later, there was no further fluid drainage. The patient was asymptomatic and without recurrent disease at follow-up 3 months later. CONCLUSIONS: Pelvic lymph node dissection may cause postoperative chylous ascites. Paracentesis with a continuous low-pressure drainage system can be an effective conservative treatment for postoperative chylous ascites.
