RESUMO

Calcifying fibrous pseudotumors (CFT) are rare benign lesions diagnosed by histological and immunohistochemical studies. Our case presents a rare detection of a CFT in the parietal peritoneum. These lesions can be falsely interpreted as myomas or adnexal masses and thus gynecologists should be aware of the existence of CFTs.

RESUMO

Uveal melanomas represent approximately 5% of all human melanomas. Omental metastases are often diagnosed as secondary metastatic sites and only a few cases have been described as the first single manifestation of distant metastasis. In this case image, we illustrate the interesting appearance of the metastatic localization of metastatic uveal melanoma.

RESUMO

Cytokines are a type of protein that play an important role in the immune response and can also affect many physiological processes in the body. Cytokine polymorphisms refer to genetic variations or mutations that occur within the genes that code for cytokines, which may affect the level of cytokine production and function. Some cytokine polymorphisms have been associated with an increased risk of developing certain diseases, while others may be protective or have no significant effect on health. In recent years, the role of cytokine polymorphisms in the development of recurrent pregnancy loss (RPL) has been studied. RPL or miscarriage is defined as the occurrence of two or more consecutive pregnancy losses before the 20th week of gestation. There are diverse causes leading to RPL, including genetic, anatomical, hormonal, and immunological factors. With regard to cytokine polymorphisms, a few of them have been found to be associated with an increased risk of RPL, for instance, variations in the genes that code for interleukin-6, tumor necrosis factor-alpha, and interleukin-10. The exact mechanisms by which cytokine polymorphisms affect the risk of recurrent miscarriage are still being studied, and further research is essential to fully understand this complex condition. This brief review aims to summarize the recent literature on the association between cytokine polymorphisms and RPL.

RESUMO

Background: Ovarian/fallopian tube cancer is the deadliest gynecological malignancy. Most cases are diagnosed at an advanced stage, typically after the cancer has spread to the peritoneal cavity, or via lymphatic drainage. The presence of distant lymph node metastasis in the inguinal region is a rare manifestation of lymphatic metastasis. Since the 2014 FIGO staging revision, ovarian cancer patients with inguinal metastasis are classified as stage IVB. However, the clinical significance of such an upstaging remains under investigation. Materials and Methods: Both Scopus and PubMed / MEDLINE databases were utilized, by inputting the following combination of keywords: (Ovarian cancer OR Fallopian tube cancer) AND (Inguinal lymph node AND Metastasis) on June 31st, 2023. The time of publication and text availability were not considered when searching the databases and all relevant articles in English were initially accepted. Results: Twelve patients from equal number of case reports were included in our review. Mean age of diagnosis was 56,5 years old, with 3 out of 12 women to be premenopausal at the time of diagnosis. Regarding the histologic type, 67% (8 out of 12) of the cases were serous adenocarcinoma and 4 patients (33%) were diagnosed with fallopian tube malignancy. All patients, except one, were treated with primary cytoreductive surgery. In all patients optimal cytoreductive surgery was achieved. All patients, except one, received adjuvant chemotherapy. Regarding the disease-free survival, mean DFS is calculated approximately at 2 years (23,1 months). Conclusion: Inguinal lymph node metastases from ovarian / fallopian tube malignancy as initial site of metastasis is extremely rare. However, patients with inguinal masses should be investigated for ovarian / fallopian malignancy. Further investigation ought to be conducted to enlighten the pathway and the oncological significance of inguinal lymph node metastasis in ovarian cancer patients.

RESUMO

The presence of stem cells has been previously described in human precancerous and malignant cervical cultures. Previous studies have shown a direct interplay of the stem cell niche, which is present in practically every tissue with the extracellular matrix. In the present study, we sought to determine the expression of stemness markers in cytological specimens collected from the ectocervix among women with cervical insufficiency during the second trimester of pregnancy and women with normal cervical length. A prospective cohort of 59 women was enrolled of whom 41 were diagnosed with cervical insufficiency. The expression of OCT-4 and NANOG was higher in the cervical insufficiency group compared to the control group (-5.03 (-6.27, -3.72) vs. -5.81 (-7.67, -5.02) p = 0.040 for OCT4) and (-7.47 (-8.78, -6.27) vs. -8.5 (-10.75, -7.14), p = 0.035 for NANOG. Differences in the DAZL gene were not significantly different (5.94 (4.82, 7.14) vs. 6.98 (5.87, 7.43) p = 0.097). Pearson correlation analysis indicated the existence of a moderate correlation of OCT-4 and Nanog with cervical length. Considering this information, the enhanced activity of stemness biomarkers among pregnant women diagnosed with cervical insufficiency may be predisposed to cervical insufficiency, and its predictive accuracy remains to be noted in larger population sizes.

RESUMO

Background: Human papilloma virus (HPV) is considered a successful pathogen as it has the ability to evade host immune responses and establish long-term persistent infection. It has been reported that programmed death ligand 1 (PDL-1) expression is correlated with HPV-positivity and is increased with lesion progression or tumor metastasis in cervical cancer. The expression of microRNAs (miRNAs) is often deregulated in cancer, and their potential targets are affected. Methods: RNA was extracted from formalin-fixed paraffin-embedded (FFPE) cervical samples of different histological types, previously typed for the presence of HPV. A specific quantitative polymerase chain reaction (qPCR) protocol with SYBR Green was used to check for the expression of four miRNAs that were computationally predicted to target PDL-1. Results and conclusion: hsa-miR-20a-5p and hsa-miR-106b-5p showed an expression increase with the severity of the lesions, while hsa-miR-125b-5p depicted a significant decrease in its expression in cancerous samples when compared to normal samples.

RESUMO

OBJECTIVES: The present case-control study investigates whether TP53 Arg72Pro variant (rs1042522) serves as a risk factor for recurrent pregnancy loss (RPL) in Greek women. METHODS: The study group consisted of 100 patients with at least two miscarriages of unexplained etiology, before the 24th week of gestation. The control group included 106 women with no pregnancy loss history. DNA was extracted and genotyped using specific primers for PCR amplification of the Arg72 and Pro72 alleles. Sanger sequencing was used for the discrimination between heterozygotes and homozygotes for Arg72Pro variant. RESULTS: This is the first study demonstrating the statistically significant higher frequency of TP53 Arg72Pro variant in Greek RPL women compared to controls (38% vs. 6.6%; OR=8.6682, 95% CI: 3.6446-20.6160; p<0.0001). GC genotype (Arg/Pro) and CC genotype (Pro/Pro) were statistically more common in RPL patients than in controls (16% vs. 1.9%; p=0.0027, and 22 vs. 4.7%; p=0.0008, respectively). C allele frequency was statistically significant higher in RPL group than in controls (30.0 vs. 5.7%; p<0.0001). According to the inheritance mode analysis, the model that best fit the data was the dominant model (OR=8.67, 95% CI=3.64-20.62; p<0.0001). CONCLUSIONS: The is the first study disclosing strong evidence that TP53 rs1042522 is significantly associated with a higher risk for recurrent pregnancy loss in Greek women following a dominant model, thus, serving as a genetic marker for identifying women at increased risk of recurrent miscarriages.

RESUMO

We report a rare case of a large prolapsed pedunculated uterine myoma measuring 15 cm in its greater diameter. In order to make a surgical procedure safe and feasible, appropriate clinical predictors should be taken into account and pre- and intraoperative preparations be available to the surgeon's armamentarium.

RESUMO

BACKGROUND: Promoter region SNPs in TNF-α have been studied in association with Recurrent Pregnancy Loss (RPL) occurrence in various populations. Among them, -238G > A, -308G > A and - 376G > A have been frequently investigated for their potential role in recurrent abortions. The aim of the present study is to evaluate the correlation among TNF-α 238, TNF-α 308 and TNF-α 376 polymorphisms and recurrent pregnancy loss risk in Greek women. METHODS: This study included 94 Caucasian women with at least two miscarriages of unexplained aetiology, before the 20th week of gestation. The control group consisted of 89 Caucasian women of proven fertility, with no history of pregnancy loss. DNA samples were subjected to PCR amplification using specific primers. Sanger sequencing was applied to investigate the presence of TNF-α 238, TNF-α 308, TNF-α 376 polymorphisms in all samples. RESULTS: The TNF-α 238 and TNF-α 308 variants were both detected in RPL and control groups (7.45% vs 4.49 and 45.16% vs 36.73%, respectively), but with no statistically significant association (p-value 0.396 and 0.374, respectively). The TNF-α 376 variant was not detected at all in both control and RPL groups. When TNF-α 238 and TNF-α 308 genotypes were combined no association with RPL was detected (p-value = 0.694). In subgroup analysis by parity, RPL patients carrying the A allele reported less previous births. CONCLUSIONS: This is the first study demonstrating TNF-α 238 and TNF-α 308 gene expression and the absence of TNF-α 376 variant in Greek women with RPL. However, no association emerged between each polymorphism studied and the occurrence of recurrent pregnancy loss. Accordingly, TNF-α -308G > A, -238G > A and -376G > A variants are not considered genetic markers for identifying women at increased risk of recurrent pregnancy loss in the Greek population.

RESUMO

BACKGROUND: Molecular biology tools, such as the detection of Single Nucleotide Polymorphisms (SNPs), have been considered to assist in the management of ovarian stimulation protocols. PURPOSE: The aim of this study was to evaluate the impact of two polymorphisms, the Asn680Ser polymorphism of the FSHR gene, and the FSH ß subunit (FSHß) gene polymorphism -211 G>T, in a Greek population of women undergoing IVF/ICSI program in our center. In addition, a control group of fertile women was studied to verify whether there are differences in the genotype distribution between fertile and infertile population for both polymorphisms, as the FSHß gene polymorphism -211 G>T is studied for the first time in the Greek population. RESULTS: The FSH ß-211 G>T polymorphism, studied for the first time in the infertile Greek population, appears to be quite rare. When studying the two polymorphisms separately, statistically significant differences were obtained that concerned the LH levels. DISCUSSION: According to the combination analysis of the two polymorphisms by the number of alleles, women with 2-3 polymorphic alleles needed more days of stimulation, but there were no differences in pregnancy rates. CONCLUSION: This molecular genetic study helps to elucidate whether the polygenic combination of the Asn680Ser and FSH ß subunit -211 G>T gene polymorphisms is of additive value in the prediction of ovarian response to exogenous gonadotropins.

RESUMO

BACKGROUND: Ganglioneuromas (GNs) arise from peripheral or central areas of the autonomic nervous system, being benign lesions of neuroblastic origin. CASE: A 19-year-old Greek female patient was admitted to our clinic with symptoms of periodic lower abdominal pain and irritation since some months ago. Ultrasonography revealed a mass of 72 × 68 mm originating from the left ovary giving the characteristics of a typical dermoid cyst. Laparoscopic ovarian cystectomy was done. The histological diagnosis revealed a mature cystic teratoma with a small hidden GN. SUMMARY AND CONCLUSION: Histology remains the gold standard for their confirmation. The coexistence of GN within a mature cystic teratoma happens extremely rarely. This is one of the few cases reported in the literature.

RESUMO

Background The aim of this study was to analyze two different polymorphisms, Ser680Asn and -29 (G>A) promoter polymorphism, of the follicle-stimulating hormone receptor (FSHR) gene, individually but also in combination, in a sample of Greek women undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Materials and methods One hundred and forty-one women undergoing IVF or ICSI and 94 controls were genotyped by real-time polymerase chain reaction (RT-PCR) for the two FSHR polymorphisms. The association of the alleles with the clinical, biochemical and other parameters concerning the controlled ovarian stimulation (COS) protocol and outcome was investigated, as well as the pregnancy rate. Results The study of each polymorphism individually revealed a positive correlation of the SerSer genotype (Ser680Asn polymorphism) with higher luteinizing hormone (LH) levels on the third day of the menstrual cycle. On the other hand, the A allele for the -29 (G>A) promoter polymorphism correlated with the increased number and quality of cumulus-oocyte complexes (COCs). No differences were detected when the different genotypes of the two polymorphisms were combined - the population study was grouped according to the number of polymorphic alleles they carried (0-4 alleles). Women who presented all polymorphic alleles, AsnAsn/AA, exhibited the lowest LH levels (2.62 ± 0.68 mIU/L), but were rarely detected (n = 2, 1.4% of the studied population). Conclusions The data from this study reflect that the investigation of the combination of polymorphisms, such as FSHR -29 and Ser680Asn, could offer a valuable tool in order to evaluate and anticipate the outcome of the ovulation induction protocols, especially in the group of patients with failed attempts.

RESUMO

INTRODUCTION: BRCA1 inherited mutation carriers face a lifetime risk of 72% to develop breast cancer and a percentage of 44% risk for ovarian cancer. PRESENTATION OF CASE: We present a case of a 35-year old Caucasian woman who, after the excision of a possible malignant finding on the right breast, was diagnosed with ductal breast carcinoma. The patient treatment included first chemotherapy and radiotherapy and then prophylactic bilateral mastectomy with plastic reconstructive surgery. At the age of 37, she underwent prophylactic laparoscopic bilateral salpingoophorectomy. The histological diagnosis of the surgical specimens was suggestive of a unilateral invasive high grade salpingeal cancer and the patient underwent an abdominal hysterectomy by laparotomy, omentectomy and bilateral pelvic lymphadenectomy. DISCUSSION: Women with known BRCA mutations are strongly recommended to consider a risk reducing prophylactic salpingoophorectomy (RRSO) from their early 40 s to gain maximum benefit in cancer risk reduction from the procedure. The prevalence of occult carcinomas in BRCA1 carriers is almost 1, 5% if the prophylactic bilateral salpingoophorectomy is performed before the age of 40, while this percentage may be increased to 3, 8% for women who undergo the surgery between 40 and 49 years. CONCLUSION: We present an interesting case, of an accidentally revealed salpingeal carcinoma via RRSO in an asymptomatic young premenopausal woman.

RESUMO

INTRODUCTION: Benign metastasizing leiomyomas represent benign lesions consisted by leiomatosous tissue and could be observed in positions away from their usual localization, the human uterus. They commonly affect women that have undergone total hysterectomy. Approximately 100 similar cases have been reported in the literature, so the case we present is rare and reviewing the literature and needs to be reported. PRESENTATION OF CASE: We report a case of a 55 year old Greek woman, gravida five and para three, who attended our unit 3 years ago complaining of occasionally lower abdominal pain and irritation the last months. Fourteen years ago she underwent abdominal hysterectomy and left salpingo-oophorectomy due to a 13 cm uterine leiomyoma. In the meantime she underwent two surgical procedures for recurrent benign leiomyomas. DISCUSSION: When patient was admitted at this time, clinical examination revealed a palpable mass of 5 cm. The transvaginal ultrasonography revealed 3 masses in the lower pelvis of unknown origin. The patient underwent a new laparotomy revealing three masses of benign leiomyomas with low mitotic activity. CONCLUSION: Our case supports the recurrent appearance of leiomyomas in pelvis after total abdominal hysterectomy and is one of few reports in literature where the tumors appear in the same patient both in estrogen rich and estrogen poor environment. Additionally, we show the importance of transvaginal ultrasonography and 3 dimensional power Doppler in the differential diagnosis of pelvic masses. Thus, transvaginal ultrasonography seems to be a pivotal tool for the diagnosis and follow up of these challenging lesions.

RESUMO

INTRODUCTION: Lobular breast carcinoma includes lobular carcinoma in situ (LCIS) and invasive lobular carcinoma (ILC). The association of LCIS with total metastatic lobular breast cancer is very rare. PRESENTATION OF CASE: We present a case of a totally metastatic lobular breast cancer in an asymptomatic 64-year-old postmenopausal woman, with no suspicious microcalcifications in mammography. A total hysterectomy with bilateral salpingo-oophorectomy, pelvic lymphadenectomy, infracolic omentectomy and appendectomy was performed along with a quadrantectomy of the upper outer quadrant of left breast, and systematic isolateral lymphadenectomy of the left axilla. DISCUSSION: LCIS is usually undetectable because it isn't associated with clinical abnormalities in clinical examination and is presented in mammography as microcalcifications or focal asymmetric densities. ILC histopathologic features are responsible for the high false-negative rates on mammography, leading to moderate detection sensitivity. CONCLUSION: Our case is a very rare condition. No 'similar' case have been described in the literature so far.

RESUMO

INTRODUCTION: Ovarian vein thrombosis is a rare but potentially serious complication after surgical and gynecologic procedures such as oophorectomy and hysterectomy. The association of this event with laparoscopic hysterectomy in particular, is very rare. Only two cases have been described so far. PRESENTATION OF CASE: We present a case of ovarian vein thrombosis after laparoscopic hysterectomy in a 40-year-old with deep endometriosis and multiple intramural uterine myomas. Laparoscopic hysterectomy, left oophorectomy, right salpingectomy, and suspension (ovariopexy) of the right ovary on the ipsilateral round ligament of the uterus were performed, using bipolar electrocautery as a hemostatic tool. DISCUSSION: The 7th postoperative day the patient presented to our hospital complaining of abdominal pain and fever. An abdominal CT scan demonstrated a filling defect and enlargement of the right ovarian vein, a finding compatible with ovarian vein thrombosis. She was treated with low molecular weight heparin (LMWH). On the 19th postoperative day, an MRI scan was performed and did not reveal any pathological findings of the right ovarian vein. The patient was discharged on LMWH for three months. Post treatment evaluation for thrombophilia was negative for pathological findings. CONCLUSION: Our case is a very rare condition. Only two 'similar' cases have been described in the literature so far. Bipolar electrocautery and ovariopexy on the ipsilateral round ligament during laparoscopic hysterectomy should be evaluated further as possible contributing mechanisms for the thrombus formation.

RESUMO

INTRODUCTION: Breast involvement in Non Hodgkin Lymphoma is a rare entity as it accounts for 2.2% of all extranodal lymphomas. PRESENTATION OF CASE: A 59-year-old woman was referred to our Breast Unit because of two nodules of the right breast newly discovered during her annual mammography. Moreover, during the physical examination, a red-brown itchy lump of the scalp was discovered. The punch biopsies of the scalp lesion and ultrasound-guided core biopsies of both nodules of the right breast, revealed the presence of diffuse large B-cell Non Hodgkin Lymphoma in all tissue specimen sites. DISCUSSION: Breast lymphomas represent an uncommon form of localized extranodal lymphomas that can be classified as Primary (PBL) or Secondary (SBL) breast lymphomas. CONCLUSION: The value of preoperative diagnosis should be underlined as the patient avoids unnecessary surgical intervention and has earlier initiation of chemotherapy.

RESUMO

BACKGROUND: Mesenteric cyst is a rare clinical entity especially in pregnancy; therefore, few cases have been reported in the literature. The standard method of their treatment is surgical excision either with laparotomy or laparoscopy. In addition, mesenteric vein thrombosis is a rare and life-threatening condition in pregnancy and needs immediate treatment because it can lead to intestinal necrotic ischemia. This is the first report of the coexistence of mesenteric cysts and mesenteric vein thrombosis during gestation. CASE PRESENTATION: A 27-year-old Greek woman, gravida 2 para 1, presented at 10 weeks' gestation to the Emergency Unit of our hospital complaining of diffuse abdominal pain which deteriorated the last 3 days, which was localized in her right iliac fossa, along with vomiting. She had undergone open laparotomy and right salpingo-oophorectomy at the age of 23 due to an ovarian cyst. Besides this, her personal and family medical history was unremarkable. She had never received oral contraceptives or any hormone therapy. On arrival, a clinical examination revealed tenderness on palpation of her right iliac fossa, without rebound tenderness or muscle guarding. Within 10 hours of hospitalization, her symptoms deteriorated further with rebound tenderness during the examination, tachycardia, and a drop of 12 units in her hematocrit value. An emergency laparotomy was performed. Two mesenteric cysts and a 60 cm necrotic part of her intestine were revealed intraoperatively. In the postoperative period, she complained of acute abdominal pain, tachycardia, and dyspnea. Computed tomography imaging revealed mesenteric vein thrombosis and pulmonary thromboembolism. She was treated with low molecular weight heparin and she was discharged on the 11th postoperative day. CONCLUSIONS: To the best of our knowledge, this is the first report in the literature of a simultaneous mesenteric cyst and mesenteric vein thrombosis in pregnancy. It is known that pregnancy is a state of hypercoagulation and clinicians should bear in mind this rare clinical condition in their diagnostic algorithm for acute abdominal pain.

RESUMO

Cancer cells acquire unique secretome compositions that contribute to tumor development and metastasis. The aim of our study was to elucidate the biological processes involved in cervical cancer, by performing a proteomic analysis of the secretome from the following informative cervical cell lines: SiHa (HPV16+), HeLa (HPV18+), C33A (HPV-), and HCK1T (normal). Proteins were analyzed by 2D gel electrophoresis coupled to MALDI-TOF-MS. Enrichment of secreted proteins with characteristic profiles for each cell line was followed by the identification of differentially expressed proteins. Particularly, transforming growth factor-beta-induced protein ig-h3 (Beta ig-h3) and peroxiredoxin-2 (PRDX2) overexpression in the secretome of cancer cell lines was detected and confirmed by Western blot. Bioinformatics analysis identified the transcription factor NRF2 as a regulator of differentially expressed proteins in the cervical cancer secretome. NRF2 levels were measured by both Western blot and Multiple Reaction Monitoring (MRM) in the total cell extract of the four cell lines. NRF2 was upregulated in SiHa and C33A compared to HCK1T. In conclusion, the secreted proteins identified in cervical cancer cell lines indicate that aberrant NRF2-mediated oxidative stress response (OSR) is a prominent feature of cervical carcinogenesis.

RESUMO

INTRODUCTION: Giant juvenile fibroadenomas represent only the 0.5% of all fibroadenomas, constituting a rare condition in adolescence. In prepuberty, the presence of this condition is extremely rare. PRESENTATION OF CASE: We describe a rare case of a 12- year-old Caucasian girl who presented to our Hospital complaining of a palpable mass with rapid enlargement in her right breast that she had first noticed 3 months ago. Her menarche hadn't occurred yet. DISCUSSION: Physical examination showed a giant mass of 15 × 13 cm in the right breast. The patient was further evaluated via ultrasonography showing a sole large lesion of 13 × 12 cm in the right breast. A surgical procedure under general anesthesia was performed. Histopathological findings after the surgical excision were suggestive of giant juvenile fibroadenoma. The patient has a normal breast development over a period of 9 month follow up. CONCLUSION: Giant juvenile fibroadenomas should be included in differential diagnosis of a breast mass in prepubertal girls despite the fact that they are very rare in prepuberty, tend to appear later during adolescence and their prevalence is lower in Caucasians. The remarkable size and the rapid growth of the lesion should not be ruled out in the diagnostic process of an adolescent breast.
