A case of granulocyte colony-stimulating factor (G-CSF)-producing small-cell carcinoma of the uterine cervix is described. In a 70-yr-old woman, clusters of small cells with hyperchromatic nuclei at a high nuclear/cytoplasmic ratio were detected cytologically in the cervix. These clusters were diagnosed as a small-cell neuroendocrine carcinoma by the(More)
Diffusely increased skull uptake (a hot skull) is often seen in patients with bone metastases and metabolic diseases. This finding is also, however, noticed in normal bone scans of aged women. To determine whether the hot skull could be considered a normal variant in elderly women and is associated to menopause, we studied 282 normal bone scans (166 women(More)
OBJECTIVE Mature cystic teratoma of the ovary (MCT) is the most common ovarian cystic disease in young women. Although it is a rare occurrence, some cases develop malignant transformation (MT), which results in serious consequences. However, MT is currently diagnosed only by postoperative pathology in most cases. We have conducted a retrospective study in(More)
Ovarian small cell carcinoma of hypercalcemic type is a rare neoplasm that typically occurs in young females. We describe three cases of ovarian small cell carcinoma of hypercalcemic type occurring in patients aged 24, 37, and 25 years. The first patient had stage IIc disease and had primary surgery with a left salpingo-oophorectomy and omentectomy,(More)
Laparoscopic surgery by abdominal wall lifting may be less invasive than by pneumoperitoneum, because the influence of the pneumoperitoneum can be avoided. We have performed laparoscopic surgery without pneumoperitoneum by lifting the full layer of the abdominal wall using two unique kinds of lifting bars that we developed. We have used this method on a(More)
OBJECTIVE To evaluate the significance of the expression of HER-2/neu as a prognostic factor, we retrospectively examined its overexpression rates chiefly in ovarian clear cell adenocarcinoma (CCA) and their relationships with FIGO stage, lymph node metastasis, and prognosis. METHODS In addition to 90 specimens of CCA (stage I, 52; stage II, 7; stage III,(More)
A 67-year-old man underwent graft replacement for the descending thoracic aortic aneurysm with the aid of temporary external bypass. Intraoperative evoked spinal potentials (ESPs) were monitored to detect the spinal cord ischemia. Incomplete paraplegia with sensory dissociation was developed in this patient after surgery, despite well maintained ESPs(More)
It is well known that the 5-year survival rate of advanced ovarian cancer patients greatly improved after the appearance of cisplatin. Recently, paclitaxel has been reported to be effective in the treatment of cisplatin-resistant ovarian cancer. However, control of intraperitoneal lesions is still the biggest problem in this treatment, and attention is(More)
