The association of low-grade endometrioid carcinoma with undifferentiated carcinoma (UC) was first reported in endometrium carcinoma, termed with dedifferentiated carcinoma (DC). However, the coexistence of low-grade endometrioid carcinoma …

Women with endometriosis (EMs) have unexplained infertility. The recently identified telocytes (TCs) might participate in the maintenance of structural and functional integrity of oviduct tissue, but so far the involvement of TCs in EMs-aff…

Genome-wide association studies (GWASs) have mainly focused on top significant single nucleotide polymorphisms (SNPs), most of which did not have clear biological functions but were just surrogates for unknown causal variants. Studying SNPs…

To mine possibly hidden causal single-nucleotide polymorphisms (SNPs) of melanoma, we investigated the association of SNPs in 76 M/G1 transition genes with melanoma risk using our published genome-wide association study (GWAS) data set with…

Endometrial stromal sarcoma (ESS) arising in the vagina is an extremely rare extrauterine endometrial stroma sarcoma, with only 4 cases reported in the literature up to date. Here we report a case of neoplasm originating from vagina. A 32-y…

Submucosal tumors (SMTs) are usually discovered fortuitously during routine endoscopy, including various non-neoplastic and neoplastic conditions. Endoscopic ultrasound (EUS) is considered to be the best imaging procedure to characterize SM…

ObjectiveThe true incidence of ovarian tumors in children is unknown. Few studies beyond case reports and case series have been published concerning pediatric ovarian tumors. Herein we review a large number of ovarian tumor cases.MethodsThe…

BACKGROUND: The aim of this study was to investigate the appropriate measures for diagnosing and treating perineal endometriosis (PEM) with anal sphincter involvement. METHODS: Between January 1992 and April 2011, the clinical features, dia…

BackgroundUterine fibroids (UFs) are benign growths within the uterine muscle and are present in 30% of women during their reproductive years. With the exception of hysterectomy, there are no effective medical and surgical treatments for wo…

BackgroundThe lymphatic system is a major route for cancer cell dissemination and also a potential target for antitumor therapy. To investigate whether increased lymphatic vessel density (LVD) is a prognostic factor for nodal metastasis and…

Ovulation has long been regarded as a process resembling an inflammatory response. Recent studies indicate that genes associated with innate immune responses were also expressed during the ovulation process. Because the innate immune genes …

OBJECTIVE: To analyze the clinical presentation of perineal endometriosis and evaluate its treatment. METHODS: Clinical data were analyzed from the records of 36 patients with perineal endometriosis who were operated on between 1983 and 20…

BackgroundHormonally active environmental exposures are suspected to alter onset of puberty in girls, but research on this question has been very limited.ObjectiveWe investigated pubertal status in relation to hormonally active environmenta…

IntroductionOvulation is similar to an inflammatory response and is associated with increased production of prostaglandins as well as local growth regulatory factors. However, the expression and function of innate immune cell-related genes …

Malignant change of endometriosis in a cesarean scar (CS) is rare. We report a case of carcinosarcoma arising from atypical endometriosis in a CS scar, which was successfully treated with complete excision of the lesion and repair of the ab…

OBJECTIVE: To investigate the clinical characteristics, treatment, and factors of recurrence of abdominal wall endometriomas (AWE). METHOD: Sixty-four cases of AWE diagnosed at Peking Union Medical College Hospital (PUMCH) from 1983 to 2003…

OBJECTIVE: To report the diagnosis and treatment of 11 cases with perineal endometriosis (PE). METHODS: Eleven patients with PE treated in our department from 1983 - 2000 years were analyzed retrospectively and were followed for 0.5 - 7.0 y…

OBJECTIVE: To make a comparative study of HLA-DQA1 and HLA-DRB1 allele frequencies in the cases of endometriosis and adeonmyosis. METHODS: The allelic types of HLA-DQA1 and HLA-DRB1 were detected by polymerase chain reaction-sequence specif…

OBJECTIVE: To analyze the clinical features of congenital vaginal atresia (CVA) with normal uterine corpus and investigate the relationship between the subtypes and management. METHODS: Sixteen cases, partical atresia (type I) 10 and comple…

OBJECTIVE: To explore the clinic manifestations, diagnostic methods and principles of management in the secondary infection of the endometriotic cysts of ovary. METHODS: Thirteen cases of the infected ovarian endometriotic cysts were analys…

OBJECTIVE: The technique and experience of vaginal hysterectomy for large uterus of 25 cases was reported. METHODS: Vaginal hysterectomy for 25 cases of uterine fibroids and adenomyosis were performed. The uterine sizes enlarged as large as…
