The matrix metalloproteinases (MMP) function as regulators of the dynamic tissue remodeling that occurs in the endometrial lining of the uterus during the normal human menstrual cycle; dysregulation of the MMPs is thought to contribute to the development of both endometriosis and endometrial cancer (1). MMP-1 expression was found to be significantly higher in endometriotic lesions than in surro...

We describe a patient with a histologically verified undifferentiated endometrial cancer who initially declined treatment, thus permitting study of the in vivo growth kinetics of the tumor. 266 days later, the patient was diagnosed with extensive symptomatic pelvic, abdominal, mediastinal, lung and supraclavicular metastases confirmed by imaging. During the untreated phase of 9.2 months, the tu...

Tamoxifen is widely used for endocrine treatment and breast cancer prevention. It acts as both an estrogen antagonist in breast tissue and an estrogen agonist in the female lower genital tract. Tamoxifen causes severe gynecologic side effects, such as endometrial cancer. This review focuses on the effects of prolonged tamoxifen treatment on the human female genital tract and considers its tumor...

Endometriosis is a painful disorder characterized by endometrial tissue outside the uterine cavity. It usually affects the pelvis, but in rare cases it might extend to other parts of the body. The report is based on a case of a 39-year-old woman, who presented symptoms of acute appendicitis and diagnosis confirmed with ultrasonography and a computed tomography scan procedures. Laparoscopic appe...

UNLABELLED A 45 year old woman underwent Laparoscopy-assisted total hysterectomy with staging procedure following a diagnosis of endometrial endometrioid adenocarcinoma on her endometrial biopsy. The hysterectomy specimen showed a FIGO I stage 1a, endometrioid carcinoma. A separate polypoid lesion in the endometrium, distinct from the carcinoma, was also identified. Microscopically the polypoid...

BACKGROUND The human endometrium undergoes cyclical regeneration throughout a woman's reproductive life. Ectopic implantation of endometrial cells through retrograde menstruation gives rise to endometriotic lesions which affect approximately 10% of reproductive-aged women. The high regenerative capacity of the human endometrium at eutopic and ectopic sites suggests the existence of stem/progeni...

Purpose : Only a few studies on diffusion weighted (DW) imaging of ovarian lesions have been reported (1-3). In previous studies, the role of DW imaging in distinguishing between benign and malignant cystic tumors may be limited. Katayama et al (3) reported that apparent diffusion coefficient (ADC) values may not provide additional information, especially to discriminate benign from malignant l...

The individual nuclear size was studied in three groups of endometrial samples (simple hyperplasia -SH-, atypical hyperplasia -AH-, and well-differentiated adenocarcinoma -WDA-). The application of recent semiquantitative systems in combination with stereological methods permits a simple, quick and unbiased estimation of the volume-weighted mean nuclear volume vv(nucl). We have found an increas...
