OBJECTIVE Myomatous erythrocytosis syndrome is a rare complication of uterine leiomyoma caused by erythropoietin (EPO) that is produced by tumor cells. We assessed the EPO expression in leiomyomas and investigated the effects of EPO on the tumor growth. STUDY DESIGN Tissue samples were collected from 114 patients with uterine leiomyomas who underwent(More)

BACKGROUND In Japan, cervical cancer (CC) deaths among women aged <50 years have doubled over the last three decades. Obtaining age-specific CC mortality rates among young women is important for taking measures against CC. Age-adjusted CC mortality rates for all ages are inadequate because of the classification of 'uterine cancer, not otherwise specified'(More)
OBJECTIVE Pregnancy and lactation-associated osteoporosis (PLO) is a rare disease, which can lead to vertebral fractures in women of reproductive age. No treatment strategy for PLO has been established. Here we report a case of PLO treated with teriparatide followed by denosumab, in which remarkable improvement in bone mineral density (BMD) was achieved. (More)
Atypical protein kinase C λ/ι (aPKCλ/ι) is a regulator of epithelial cellular polarity. It is also overexpressed in several cancers and functions in cell proliferation and invasion. Therefore, we hypothesized that aPKCλ/ι may be involved in development and progression of cervical intraepithelial neoplasia (CIN), the precancerous disease of cervical cancer(More)
Hemorrhagic ascites caused by endometriosis is extremely rare, and its treatment is under discussion. We report a case of recurrent endometriosis-related ascites treated with dienogest (DNG). A 35-year-old nulliparous Japanese woman with a history of infertility presented with worsening dysmenorrhea and abdominal distention caused by massive ascites. The(More)
STUDY OBJECTIVE To evaluate a new magnetic resonance imaging (MRI) grading system for preoperative differentiation between benign and variant-type uterine leiomyomas including smooth muscle tumors of uncertain malignant potential (STUMPs). DESIGN Retrospective analysis (Canadian Task Force classification III). SETTING Teaching hospital (Teine Keijinkai(More)
