Chorioangioma is the most frequent nontrophoblastic tumor of the placenta with a incidence ranging from 0.01 to 1.3%. Vascular anomalies of the placenta coincidental with infantile hemangioendothelioma (IH) of the liver are rarely described. Here we report a case of a large chorioangioma of the placenta associated with cutaneous hemangiomatosis and IH of the liver. The relationship between hemangiomas and placental chorioangioma is discussed.

Objective(s)(1) To investigate the cesarean rate among actively practicing obstetricians in Turkey and reasons why they choose this mode of delivery for themselves/partners. (2) To investigate the attitudes, practices, and beliefs with respect to cesarean delivery on maternal request (CDMR) among actively practicing obstetricians in Turkey.Study designThis is a descriptive study performed at 7th Congress Of Turkish Society Of Gynecology and Obstetrics. A self-administered questionnaire was used for data collection. During the congress, from the obstetricians attending the congress, 500 were randomly selected; due to the room numbers, the questionnaires (total, 500) and the consent forms were distributed every fourth room. The sampled obstetricians were instructed to return the completed questionnaires and signed consent forms to the congress information desk located throughout the congress. In total, 387 (77.4%) obstetricians responded.ResultsOf the respondents (if female) or their partners (if male), 239 (61.8%) respondents had undergone at least one previous cesarean section (CS), and, of these, 212 (88.7%) were primary elective cesarean deliveries. The most common reason influencing the decision of obstetricians in choosing CS for themselves/partners was reduced anorectal trauma (63.6%). In addition, 158 (40.8%) of the respondents believe that every woman has the right to request a cesarean as a mode of delivery. About half of the respondents (53.2%) said that they would perform a patient-requested CS. The most common reason why obstetricians perform CS due to maternal request was ‘anxiety of patient and her partner and due to their insistence’.ConclusionsTwo-thirds of Turkish obstetricians prefer CS as mode of delivery for themselves/partners. Also half of the obstetricians in our study believe that a woman has the right to request and obtain CDMR, and half of them would agree to perform one.

Objective Aggressive angiomyxoma (AA) is found mainly in the pelvis and perineum, with a female-to-male ratio of approximately 6:1. Although it is a slow growing tumor, AA has a marked tendency to local recurrence with a low metastasis capacity. The study aimed to describe a case of vulvar angiomyxoma recurred almost 20 years after its initial surgery. Materials and Methods We report the case of a 57-year-old gravida 5 para 4 woman with vulvar AA arising from the left labium majus, which recurred 20 years after initial surgery. There was a nontender, solid, mobile mass on the left vulva, which was 25 x 30 cm on physical examination. A pelvic computed tomographic scan showed a mass measuring 26 x 10 x 14 cm originating from left vulvar region, which has a fatty tissue density. Result Under general anesthesia, total excision of the tumor was performed. Macroscopically, the tumor weighed 723 g and measured 33 x 20 x 10 cm. The histopathological examination of the specimen revealed a myxoid tumor with sparse infiltrates of spindle-shaped to stellate cells and vessels of varying sizes. The final histopathological diagnosis was AA. Conclusions Aggressive angiomyxoma may form extremely large tumors, and recurrence is not rare even many years after primary surgery.

Sebaceous gland hyperplasia of the vulva

Sevgi Bakaris; Hakan Kiran; Gurkan Kiran

A 37-year-old gravid 1, para 1 woman complained of secondary infertility and the appearence of a lesion on her vulva; vulvar discomfort and enlargement had been present for 8 years, and there was related coital pain. She had regular menstrual cycles, and was not taking any oral contraceptives. Examination revealed labia minora which were bilaterally enlarged with 2.5 × 2 × 1 cm regularly shaped polypoidal tumours. These polypoidal masses were smooth, multilobed and mildly tender with palpation; no bleeding or purulence was noted, and they were covered by normal appearing skin. The swellings were excised and her symptoms were relieved. Microscopically, the tumour originated from sebaceous ducts and sebaceous glands, and were composed of numerous lobules, and extended down into the dermis in a pattern of well-defined islands. The lobules consisted of greatly enlarged sebaceous gland composed of numerous lobules grouped around a centrally located, wide sebaceous duct (Fig. 1). Formation of ductal structures were seen in many areas. The sebaceous gland lobules were fully mature and there were no atypical features. Patchy chronic inflammatory cell infiltrate were also associated with the lesions. On the basis of such evidence, the diagnosis of sebaceous gland hyperplasia was made. Immunohistochemical investigation showed epithelial membrane antigen (Biogen, Fremont, CA, USA) expression in the keratinocytes of the infindibulum, the isthmus, and sebaceous duct and in the mature and immature sebocyte.

OBJECTIVE To compare the therapeutic effect of acupuncture and non-steroidal anti-inflammatory drug (NSAID) therapy in primary dysmenorrhea patients. STUDY DESIGN Thirty-five young women with a diagnosis of primary dysmenorrhea were recruited for the study. Their dysmenorrhea severity was rated by visual analog scale (VAS) immediately prior to entry into the study. They were randomly divided into two groups; and the following month they were given NSAID (group 1, n=24) or acupuncture treatment (group 2, n=11). Pain was rated again using VAS during menstruation in both groups. RESULTS After one months treatment, pain scores were significantly lower in both groups (p<0.05). Mean pain scores decreased by 52.2% and 69.5% in the NSAID and acupuncture groups, respectively. CONCLUSION Acupuncture was as effective as NSAID therapy for patients with primary dysmenorrhea. Since this was a pilot study with a small sample size and short follow-up period, larger studies are needed to clarify the effect of acupuncture in the treatment of primary dysmenorrhea.

Background Preeclampsia (PE) is a hypertensive disorder that occurs in 2% to 8% of pregnancies. Although numerous studies have investigated the etiology and pathophysiology of preeclampsia, the precise pathological mechanisms remain poorly understood. Hence, in the present study malondialdehyde (MDA) levels and SOD expression, and Cu and Zn concentrations and ratios were correlated with birth weights in pregnant women with and without PE, and in non-pregnant females of reproductive age. Material/Methods Malondialdehyde (MDA) levels and superoxide dismutase (SOD) activities were determined spectrophotometrically, and Cu and Zn levels were determined using atomic absorption spectrometry in serum from 42 non-pregnant women (NP), 40 healthy pregnant women (HP), and 38 pre-eclamptic pregnant (PE) women. Subsequently, Cu/Zn ratios were calculated and associations with birth weights were analyzed using Spearman correlations. Results Cu, Zn, and MDA levels and Cu/Zn ratios were significantly higher in the PE group than in the HP and NP groups, and were significantly higher in the HP than in the NP group (p<0.001 and p<0.001; respectively). In contrast, serum Zn and SOD levels were significantly lower in the PE group than in HP and NP groups, and were significantly lower in the HP group than in the NP group (p<0.001 and p<0.001; respectively). However, only Cu and Zn levels were significantly associated with fetal birth weights (r=−0.433, p<0.001). Conclusions Serum Cu/Zn ratios may reflect vascular complications of PE, and the ensuing increases in lipid peroxidation may play important pathogenic roles.

Introduction. Although pyogenic granulomas (PG) are common and benign vascular proliferations of the skin and mucous membranes, they are relatively rare on the vulva. Case Presentation. A 57-year-old G7P7 postmenopausal woman presented with a 3-year history of a foul smell and bleeding lesions in the genital region. A gynecologic examination revealed multiple large papillomatous, pedunculated, and lobulated lesions that were cherry-red and infective in appearance. There was a 2-cm lesion at the upper intersection of the labia majora, a 2-cm lesion on the right labium majus, and a 4-cm lesion on the clitoris. The patient complained of itching, and the lesions were asymptomatic, except for occasional bleeding. All lesions were excised and sent for histopathological examination, which revealed an ulcerated polypoidal structure with extensive proliferation of vascular channels lined by a single layer of endothelium. The histopathological features were consistent with PG. Conclusion. The present case is the first case of multiple pyogenic granulomas on the vulva in a postmenopausal woman.

Hakan Kiran; Gurkan Kiran; Hasan Cetin Ekerbicer; Alanur M. Guven; Metin Kilinc

Background:  It has been hypothesised that oral oestrogen replacement therapy may increase levels of C‐reactive protein (CRP), a marker of inflammation associated with increased risk of future cardiovascular events. However, it is possible that intranasal oestrogen replacement therapy have different effects on serum CRP levels.

OBJECTIVE To evaluate the relationship of neutrophil/lymphocyte ratio (NLR) with proteinuria and blood pressure level in patients with pre-eclampsia and to investigate whether or not NLR has a role in predicting the severity of pre-eclampsia. STUDY DESIGN The study comprised 30 healthy pregnant females (Group 1), 37 females with mild pre-eclampsia (Group 2) and 40 with severe pre-eclampsia (Group 3). All the study participants were statistically compared in respect of demographic data, proteinuria levels, and blood pressure levels. RESULT Age, body mass index, and gestational weeks were similar in all the groups. Maternal NLR was determined to be significantly high in the pre-eclamptic patients (Groups 2 and 3) compared to the healthy pregnant patients (Group 1) (p=0.017). NLR was significantly higher in the severe pre-eclampsia group than in the mild pre-eclampsia group (p=0.032). A significant positive correlation was determined in correlation analysis between NLR and proteinuria (p=0.013, r=0.319). There was also a significant and positive correlation between NLR and systolic/diastolic arterial pressure (p=0.007, r=0.285; p=0.044, r=0.213, respectively). CONCLUSION In conclusion, while NLR was determined as significantly high in patients with pre-eclampsia, to be able to use this in the classification of the severity of pre-eclampsia, there is a need for further studies on a more extensive population.
