Immunohistochemical evaluation of PTEN protein in patients with endometrial intraepithelial neoplasia compared to endometrial adenocarcinoma and proliferative phase endometrium.

OBJECTIVE: The aim of this study was to reclassify endometrial hyperplasia cases and examine PTEN protein immunoreactivity compared to cases with endometrial adenocarcinoma and proliferative endometrium. DESIGN: Endometrial samples from 37 women with endometrial hyperplasia with atypia were reclassified as endometrial intraepithelial neoplasia (EIN). Eighteen were complex and 19 were simple endometrial hyperplasia. Twenty-our cases of EIN, ten endometrial adenocarcinoma cases and ten proliferative phase endometrium sections were immunostained for PTEN expression. PTEN expression was documented according to the degree of immunoreactivity as complete loss, partial loss and present. RESULTS: Twenty-four of 37 (64%) women with endometrial hyperplasia were reclassified as EIN. Complete loss of PTEN immunoreactivity was found in only one of the 24 EIN patients (4.2%), partial loss in eight of 24 (33.3%) and present in 15 of 24 (62.5%). There were no difference in PTEN immunoreactivity between EIN, endometrial adenocarcinoma and endometrial proliferation (p = 0.342). PTEN immunoreactivity was partially lost in seven and present in three of the patients with endometrial adenocarcinoma. None of the patients expressed complete loss of PTEN immunoreactivity in this group. CONCLUSION: EIN classification may provide a better and more objective assessment of endometrial hyperplasia cases. PTEN expression showed no differences among the cases of EIN, endometrial carcinoma and proliferative phase endometrium.

Hydrosonography in screening for intracavitary pathology in infertile women.

OBJECTIVES: We evaluated the value of hydrosonography in screening for intracavitary pathologies in infertile patients. METHODS: A total of 93 infertile women with suspected intracavitary lesions on transvaginal ultrasonography (TVS) underwent hydrosonography. Specimens obtained either by dilatation and curettage or hysteroscopic resection were compared with findings on TVS and hydrosonography. RESULTS: Pathology confirmed the presence of sonographically diagnosed intracavitary lesions in 40 out of 66 (60%) women. The sensitivity, specificity, positive predictive value, and negative predictive value of TVS for the detection of endometrial cavity lesions were 78%, 38%, 61%, and 59%, respectively. Forty-six out of 71 (65%) women who were found to have intracavitary lesions on hydrosonography were pathologically confirmed. The sensitivity, specificity, positive and negative predictive value of hydrosonography in the detection of endometrial cavity lesions were 90%, 40%, 65%, and 77%, respectively. CONCLUSIONS: Hydrosonography is a useful procedure in screening for intracavitary pathologies and allows differentiation of intracavitary, endometrial, and submucosal abnormalities.

Postmenopausal endometrial cancer screening: is there a correlation between transvaginal sonographic measurement of endometrial thickness and body mass index?

OBJECTIVE: The aim of this study was to correlate the body mass index with transvaginal sonographic measurement of endometrial thickness in a cohort of postmenopausal women who were admitted for endometrial cancer surveillance. MATERIAL AND METHODS: Transvaginal sonographic measurement of endometrial thickness was performed in 97 postmenopausal women who attended the gynecology clinic for endometrial cancer screening with no history of hormone replacement therapy and correlated with body mass index. Baseline characteristics including age, years since menopause and body mass index were recorded for each subject. The relationship between transvaginal sonographic endometrial thickness and baseline characteristics was assessed in each. RESULTS: Body mass index was significantly correlated with years since menopause (r = 0.292, p = 0.004) and age (r = 0.243, p = 0.01) but not with endometrial thickness (r = -0.07, p = 0.454). Endometrial thickness versus time since menopause correlation was found to be significant (r = 0.274, p = 0.03) in patients with a body mass index lower than 30. CONCLUSION: The present findings indicate that endometrial thickness does not differ with body mass index in the screening of postmenopausal women for endometrial cancer.

Large cell neuroendocrine carcinoma of the uterine corpus metastatic to brain and lung: case report and review of the literature.

Neuroendocrine carcinoma of the uterine corpus is a rare aggressive tumor with a similar unfavorable outcome to that of the cervix. The large cell type is considerably rarer than the small cell neuroendocrine carcinoma of the uterine corpus. We report a case of a 52-year-old woman who presented with a large cell neuroendocrine tumor of the uterine corpus with very aggressive clinical behavior, cerebral and pulmonary metastases six and four months after initial diagnosis and adjuvant radiotherapy, respectively. Despite successful surgical extirpation of the cerebral metastatic lesion she did not respond to chemotherapy and died four months after disease recurrence.

Acute myeloblastic leukemia in pregnancy: a case report and review of the literature.

Leukemia is a rare event during pregnancy. The presence of leukemia during pregnancy raises several concerns about the effect of pregnancy on the prognosis of leukemia, the effect of the disease on pregnancy outcome and the teratogenic and mutagenic effect of chemotherapeutic agents on the fetus. We report a case of acute myeloblastic leukemia diagnosed during the third trimester of gestation and treated with chemotherapeutic agents before delivery. The duration of pregnancy was able to be prolonged for four weeks after clinical diagnosis of the disease and then terminated by cesarean section due to the presence of signs of fetal distress.

Subcutaneous metastasis of endometrial adenocarcinoma: case report of an incidental diagnosis during abdominal sonography.

A rare case of subcutaneous metastasis from endometrial adenocarcinoma detected incidentally on the anterior abdominal wall during routine abdominal sonography is reported. A 62-year-old woman with clinical FIGO Stage IA, grade 2 endometrial mixed type (endometrioid and mucinous) adenocarcinoma was found with a subcutaneous mass located in the abdomen 18 months after initial surgery.

Comparison of hydrosonography and diagnostic hysteroscopy in the evaluation of infertile patients.

OBJECTIVE: In the present study we evaluated the value of hydrosonography in the screening for intracavitary structural pathologies in patients with a history of infertility before the implementation of assisted-reproductive technology. Hysterescopy was regarded as the gold standard procedure. STUDY DESIGN: A retrospective study. MATERIAL AND METHODS: A total number of 115 infertile women aged between 19 and 47 (33.4 +/- 5.3), who were candidates for assisted reproductive techniques, were enrolled in this retrospective analysis. The study comprised data obtained from patients undergoing infertility investigation between 2001 and 2003 at Ozel Ege IVF Center and the Department of Obstetrics and Gynecology of Ege University Faculty of Medicine. The results obtained by hydrosonography were later compared with those of hysteroscopy. Sensitivity, specificity, positive predictive value and negative predictive value for hydrosonography were calculated. RESULTS: In a total of 115 women, 53 (46%), 24 (20%), 30 (26%) and 8 (7%) were found to have normal endometrial cavities, submucous myoma, endometrial polyps and uterine septum, respectively, on hydrosonography. Forty-five (85%) of 53 women, who were supposed to have normal findings on hydrosonography, were confirmed by hysteroscopy. In the remaining eight women (15%), two had endometrial polyps, three had uterine septum, one had submucous myoma and two had intrauterine synechia on hysteroscopic examinations. The sensitivity, specificity, positive and negative predictive values of hydrosonography in the detection of structural endometrial cavity lesions were 85%, 75%, 75% and 84%, respectively. Two intrauterine adhesions were not recognized by hydrosonography. CONCLUSION: Hydrosonography may be a useful tool in the evaluation of intrauterine cavity structural pathologies in infertile patients with the exception of intrauterine adhesions. In addition, hydrosonography was found to be sensitive in the detection of intrauterine septum.

Acute leukemia in pregnancy with ovarian metastasis: a case report and review of the literature.

Acute leukemias tend to affect a younger population and are much more common in pregnant patients than chronic leukemias are. We report a case of acute lymphoblastic leukemia diagnosed during the third trimester presenting with organomegaly and thrombocytopenia. Delivery of the fetus by cesarean section was decided because of the fulminant nature of the acute leukemia within days of admission. Bone marrow biopsy revealed acute lymphocytic leukemia, French American-British L2 subtype B cell immunotype. A left ovarian mass was identified during the cesarean section which later proved to be lymphoblastic infiltration. The patient was started on induction chemotherapy consisting of vincristine, daunorubicin, prednisolone, and l-asparaginase immediately after the diagnosis. The patient died of Acinetobacter septicemia 18 days after the first admission.

The triage of squamous cell abnormalities of cervical cytology by human papilloma virus screening.

OBJECTIVE: The aim of the study was to determine the presence of human papilloma virus (HPV) infection in cervical swabs by the use of the Digene Hybrid Capture assay in a cohort of patients with squamous cell abnormalities found in cervical cytologic screening. MATERIALS AND METHODS: Thirty-four (0.3%) of 1,100 patients who came for their routine cervical cytologic screening and diagnosed as having squamous cell abnormalities were enrolled in the study. Colposcopy-directed biopsy was obtained from all study patients. HPV DNA was sought in cervical swab specimens placed in Digene transport medium by the use of the Digene Hybrid Capture assay. The findings of cervical cytology, colposcopy-directed biopsy and HPV screening were compared. RESULTS: In a total of 34 women who were diagnosed as having squamous cell abnormalities in their routine cervical cytologic screening, 15 women had atypical squamous cell lesions of undetermined significancy (ASCUS), 16 women had low-grade cervical intraepithelial lesions (LGSIL), and three women had high-grade cervical intraepithelial lesions (HGSIL). Five (15%) of these women tested positive for HPV screening in cervical swabs where four women had infection with high-risk and one woman had infection with low-risk subtypes. None of the patients with koilocytotic changes of the squamous cells in the class of LGSIL histopathologically tested positive for HPV screening. In addition, one patient diagnosed as having invasive cervical carcinoma histopathologically tested negative for HPV screening. Atypical vascularization was seen colposcopically in this 37-year-old woman who had ASCUS cytologically. CONCLUSION: HPV screening seems to have value in the triage of patients with ASCUS with no clear advantage to colposcopy-directed biopsy. The routine performance of HPV screening for the triage of patients with squamous cell abnormalities has no advantage over colposcopy-directed biopsy.

Preoperative and postoperative correlation of histopathological findings in cases of endometrial hyperplasia.

OBJECTIVES: To determine the preoperative and postoperative correlation of histopathological findings in cases of endometrial hyperplasia. MATERIAL AND METHODS: One hundred and three patients with endometrial hyperplasia detected by surgical curettage performed due to various gynecologic pathologies were treated by hysterectomy. We compared retrospectively the histopathological diagnoses found on curettage with those found on hysterectomy specimens. The classification scheme endorsed by the International Society of Gynecological Pathologists was used to classify the endometrial hyperplasia. The histologic findings found on the endometrial tissue of curettage specimens were correlated with those from hysterectomy specimens. Histopathologic evaluation was performed by a single skilled gynecologic pathologist. RESULTS: A total number of 103 women--76 (73.8%) premenopausal and 27 (26.2%) postmenopausal--were determined to have endometrial hyperplasia on histopathological evaluation of endometrial tissues obtained by endometrial curettage performed for evaluation of various bleeding abnormalities. These included 94 patients with simple hyperplasia without atypia (91.3%), two patients with simple hyperplasia with atypia (1.9%), five patients with complex hyperplasia without atypia (4.9%), and two patients with complex hyperplasia with atypia (1.9%). Histopathological evaluation of endometrial tissue obtained from hysterectomy specimens (of patients diagnosed with hyperplasia on curettage) revealed a total number of 65 cases (63.1%) with endometrial hyperplasia, and 38 cases (36.9%) with various histopathological findings. The correlation between preoperative and postoperative endometrial histologic findings was found to be statistically insignificant (r = 0.105, p = 0.29). Among 94 patients who were found to have simple hyperplasia without atypia on curettage specimens, 55.3%, were found to have simple hyperplasia without atypia, 1.1% simple hyperplasia with atypia, 5.3% complex hyperplasia without atypia, 9.6% secretory endometrium, 4.3% proliferative endometrium, 21.3% disorganized proliferative endometrium, 1.1% corpus luteum persistency, 1.1% basal endometrium, and 1.1% endometrium cancer on final hysterectomy specimens. CONCLUSION: Postoperative diagnosis of endometrial pathology might be different from that of preoperative especially in cases with simple endometrial hyperplasia without atypia.
