In 2014, we published an article titled "Novel uterine sarcoma preoperative diagnosis score predicts the need for surgery in patients presenting with a uterine mass" on the preoperative diagnosis of uterine sarcoma, in the SpringerPlus (Nagai et al. in SpringerPlus 2014, 3:678. doi:10.1186/2193-1801-3-678). Subsequently, we received several suggestions from(More)
Preoperative diagnosis of uterine sarcoma is very difficult, and currently, its diagnostic accuracy is not satisfactory. It is therefore important to perform surgery and establish the pathological diagnosis if the clinical findings and various examination findings indicate possible uterine sarcoma. We investigated the accuracy of the combination of various(More)
A 69-year-old female had a right ureteral stent placed due to ureteral stricture resulting from cervical cancer in March 2008. The ureteral stent migrated to the ureter and was not exchanged. A new ureteral stent was inserted, and was exchanged every 3 months. The patient was referred to our department to remove the forgotten ureteral stent. In January(More)
54-year-old male was introduced to our hospital in January 2012 for surgical treatment and chemotherapy. The pathological examination revealed well differentiated squamous cell carcinoma of the penis. Computed tomography and magnetic resonance imaging indicated right inguinal and pelvic lymphadenopathy. We diagnosed the tumor to be unresectable radically(More)
A 39-year-old woman was referred to our hospital due to left abdominal mass which was incidentally pointed out by computed tomographic (CT) scan. She had no symptoms. Abdominal enhanced CT showed an 85 mm solid mass, which had clustered calcifications and was enhanced weakly. Magnetic resonance imaging showed a relatively well-circumscribed mass 125 mm in(More)
A 40-year old woman, gravida 4, para 4, presented with sudden lower abdominal pain and severe vaginal bleeding at 17 weeks of gestation. Clinical symptoms and ultrasonographic finding revealed placental abruption. The volume of bleeding was heavy and led to disseminated intravascular coagulation and hypovolemic shock. We performed blood transfusion and(More)
The patient was a 38-year-old man. A cystostomy catheter had been inserted when he was 23 years of age for neuropathic bladder due to cervical spinal cord injury at 20 years of age. Purulent discharge from around the cystotomy had continued for approximately 4 months. Examination revealed the formation of a subcutaneous tumor around the cystostomy, with(More)
Primary retroperitoneal mucinous cystic tumors with borderline malignancy are rarely encountered. To date, only 12 cases have been reported in the literature. In this report, we present an additional case. A 65-year-old nulliparous woman complained of abdominal fullness. Her medical history included a hysterectomy and a single salpingo-oophorectomy(More)
BACKGROUND Invasive urothelial carcinoma, lymphoma-like/plasmacytoid variant, is a rare histological type of bladder cancer similar to plasma cells and is an aggressive variant of urothelial carcinoma associated with a poor prognosis. CASE PRESENTATION A 41-year-old Asian man was referred to our hospital due to macroscopic hematuria. Cystoscopy detected a(More)
We examined the value of pre-biopsy magnetic resonance imaging (MRI) for detecting prostate cancer. We analyzed 267 men with prostate-specific antigen (PSA) levels of 3-10 ng/ml who underwent systematic prostate needle biopsy. From April 2009 to March 2011, a total of 98 male patients underwent 16-core prostatic biopsies without pre-biopsy magnetic(More)
