RESUMO

Inflammatory bowel diseases (IBD) are significantly associated with adverse pregnancy and neonatal outcomes, though the pathomechanism is yet unknown. To investigate the relationship between IBD and adverse pregnancy outcomes by comparing neonatal outcomes and placental histopathology in two matched groups of patients with and without IBD. In this retrospective study, data of all patients who gave birth between 2008-2021 and were diagnosed with IBD were reviewed and compared to a control group matching two control cases for every IBD case. Neonatal outcomes and placental pathology were compared between the groups. Compared to the control group (n=76), the placentas of patients with IBD (n=36) were characterized by significantly lower placental weight (p < 0.001), and higher rates of maternal vascular malperfusion lesions (MVM, p < 0.001) and maternal and fetal inflammatory response lesions (p < 0.001). Neonates of patients with IBD were more frequently small for gestational age (SGA) (p=0.01), with increased rates of need for phototherapy (p = 0.03), respiratory morbidity and NICU admission (p < 0.001 for both outcomes). Multivariate logistic regression analyses adjusting for possible confounders (including maternal age, gestational age, chronic hypertension, smoking, and thrombophilia) confirmed the independent association between IBD and composite MVM lesions (aOR 4.31, p < 0.001), maternal inflammatory responses (aOR 40.22, p < 0.001) and SGA infants (aOR 4.31, p = 0.013). IBD is associated with increased rates of placental histopathological lesions and adverse pregnancy outcomes, including SGA infants. These novel findings imply the role of placental malperfusion and inflammatory processes in pregnancy complications of IBD patients, which should be followed accordingly. Approval of local ethics committee # WOMC-0219-20.

RESUMO

Background: Vulvar Paget disease (VPD) is a rare neoplastic condition exhibiting extensive multifocal involvement. It is clinically difficult to distinguish the margins of VPD from normal skin resulting in involved surgical margins leading to frequent lesion persistence and repeated excisions. Recently, fluorescein mapping has shown promise in providing accurate surgical margins in VPD. However, utilization of this technique after previous resection has not been explored. Case: A 63-year-old female underwent wide local excision of a large microinvasive VPD with involved resection margins. Two months later, the patient underwent additional surgery to excise the involved margins and for sentinel inguinal lymph nodes evaluation. With gross visualization, the vulvar skin appeared normal. However, after intravenous fluorescein sodium injection and Wood's lamp illumination, residual satellite pathological area was observed and resected, revealing more microinvasive tumor. Conclusion: Fluorescein mapping directly highlights sites of involvement in VPD and provides an improved estimation of disease extent which is otherwise not clinically visible.

RESUMO

RATIONALE & OBJECTIVE: Keratin-based hair-straightening treatment is a popular hair-styling method. The majority of keratin-based hair-straightening products in Israel contain glycolic acid derivatives, which are considered safe when used topically. Systemic absorption of these products is possible, and anecdotal reports have described kidney toxicity associated with their use. We report a series of cases of severe acute kidney injury (AKI) following use of hair-straightening treatment in Israel during the past several years. STUDY DESIGN: Case series. SETTING & PARTICIPANTS: We retrospectively identified 26 patients from 14 medical centers in Israel who experienced severe AKI and reported prior treatment with hair-straightening products in 2019-2022. FINDINGS: The 26 patients described had a median age of 28.5 (range, 14-58) years and experienced severe AKI following a hair-straightening procedure. The most common symptoms at presentation were nausea, vomiting, and abdominal pain. Scalp rash was noted in 10 (38%) patients. Two patients experienced a recurrent episode of AKI following a repeat hair-straightening treatment. Seven patients underwent kidney biopsies, which demonstrated intratubular calcium oxalate deposition in 6 and microcalcification in tubular cells in 1. In all biopsies, signs of acute tubular injury were present, and an interstitial infiltrate was noted in 4 cases. Three patients required temporary dialysis. LIMITATIONS: Retrospective uncontrolled study, small number of kidney biopsies. CONCLUSIONS: This series describes cases of AKI with prior exposure to hair-straightening treatments. Acute oxalate nephropathy was the dominant finding on kidney biopsies, which may be related to absorption of glycolic acid derivatives and their metabolism to oxalate. This case series suggests a potential underrecognized cause of AKI in the young healthy population. Further studies are needed to confirm this association and to assess the extent of this phenomenon as well as its pathogenesis.

RESUMO

BACKGROUND: Antenatal detection of abdominal circumference (AC) <10th percentile, among small for gestational age (SGA) neonates, probably reflects the severity of their growth restriction. We aimed to study neonatal outcome and placental pathology among SGA neonates in correlation to their AC measurements. METHODS: Maternal and neonatal computerized medical records and placental histopathology reports of all SGA neonates, (neonatal birth-weight ≤10th percentile), born between 24 and 42 weeks, during 2015-2018 were reviewed. Included cases with fetal biometric measurements conducted up to 7 days prior labor. Results were compared between cases with sonographic antenatal AC <10th percentile and neonates with sonographic antenatal AC ≥10th percentile. Placental lesions were classified according to "Amsterdam" Placental workshop criteria. RESULTS: The AC <10th percentile group (n = 148) was characterized by higher rate of nulliparity (p = .003), and induction of labor (p = .009), as compared to the AC ≥10th percentile group (n = 41). There were no between groups differences in the rate of maternal BMI (kg/m2), hypertensive disorders, diabetes or smoking. Neonatal hypoglycemia was more common in the AC <10th percentile group as compared to the AC ≥10th percentile group (p = .04). Placentas from the AC <10th percentile group were smaller (p < .001), with more MVM lesions (p = .02) and chronic villitis (p = .04). By multivariate regression analysis, AC <10th percentile and maternal hypertensive disorders, were found to be independently associated with placental MVM lesions, aOR = 2.43 (95% CI 1.04, 5.88) and aOR = 3.15 (95% CI 1.06, 9.31), respectively. CONCLUSIONS: Higher rate of placental maternal malperfusion lesions, chronic villitis, and more neonatal hypoglycemia characterize SGA neonates with AC <10th percentile, pointing to the importance of AC measurement as an indicator for placental insufficiency.

RESUMO

INTRODUCTION: We aimed to investigate the effect of maternal passive smoking (MPS) during pregnancy-on placental pathology and pregnancy outcomes. METHODS: A prospective case-control study. We recruited low-risk laboring women at 37+0-41 + 0 weeks between 9/2019-7/2020. MPS was defined as exposure to in-house spouse tobacco smoking of >20 cigarettes/day in the absence of maternal active-smoking. In attempt to "purify" the effect of MPS on placental pathology-we excluded cases with preeclampsia, diabetes, suspected fetal growth restriction (FGR), preterm labor, and illicit drug use. Maternal characteristics, pregnancy outcomes, and placental pathology were compared between the MPS group and a control group matched for gestational age, maternal age, and delivery date. Placental lesions were classified according to the "Amsterdam" criteria. The study was powered to detect a 33% difference in placental malperfusion lesions. Multivariable regression was performed to identify independent associations with placental malperfusion lesions. RESULTS: In labor, the MPS group (n = 115) had higher rates of meconium stained amniotic fluid (MSAF, p < 0.001) and non-reassuring fetal heart-rate (NRFHR,p = 0.006), compared to controls (n = 115). Neonates in the MPS group had higher rates of undiagnosed FGR (p = 0.01) and NICU admissions (p = 0.004). The MPS group had higher rates of placental-hypoplasia (p = 0.02) and fetal vascular malperfusion (FVM) lesions (p = 0.04). In regression analysis MPS was associated with FVM lesions independent of background confounders (aOR = 1.24 95% CI 1.10-2.65). DISCUSSION: In otherwise low-risk pregnancies, MPS was associated with higher rates of MSAF, NRFHR, undiagnosed FGR, and NICU admissions, probably mediated via placental FVM. These worrisome findings mandate patient counseling and further investigation in larger population-based studies.

RESUMO

We compared placental pathology, ultrasonographic findings, and obstetric outcomes, in gestations complicated by fetal growth restriction (FGR) with either a background of hypertensive disorder or heavy tobacco cigarette smoking. The medical records and placental pathology reports of pregnancies complicated with FGR (birthweight < 10th percentile) between December 2008 and May 2018 from a single tertiary center were reviewed. Placental pathology, ultrasound findings, and pregnancy outcomes were compared between hypertensive patients (HTN) and heavy smokers (SMO). We included 213 pregnancies: 129 (60.6%) in the SMO group and 84 (39.4%) in the HTN group. The HTN group was characterized by a higher BMI (p = 0.01), higher rates of Cesarean deliveries (p = 0.006), and a lower gestational age at delivery (35.6 ± 3.8 vs. 37.5 ± 2.9 weeks, p < 0.001). The HTN group had higher rates of placental weights < 10th percentile (p = 0.04) and maternal vascular malperfusion lesions (p < 0.001), while the SMO group had higher rates of inflammatory lesions (p = 0.04). On ultrasound, the HTN group had a higher head/abdomen circumference ratio (p < 0.001) and more abnormal Doppler studies (< 0.001). Neonates in the HTN group had lower birthweights (p < 0.001) and higher rates of NICU admissions (p = 0.002) and adverse neonatal outcome (p = 0.006). On multivariable analysis, gestational age at delivery (aOR = 0.65, 95%CI 0.55-0.87), hypertensive disorders (aOR = 1.8, 95%CI = 1.21-4.81), placental MVM lesions (aOR = 1.23, 95%CI = 1.08-5.02), and the combination of HTN+MVM (aOR = 2.63, 95%CI 1.78-7.30) were independently associated with adverse neonatal outcome. Hypertension and smoking may lead to FGR in different pathways as the two groups significantly differed in maternal characteristics, placental pathology, ultrasound findings, and neonatal outcomes. A hypertensive disorder probably represents a more hostile maternal environment than smoking and these pregnancies would probably benefit from closes monitoring.

RESUMO

INTRODUCTION: We aimed to study the correlation between the extent of placental abruption (PA), as grossly estimated immediately after delivery, and pregnancy outcomes, in correlation with placental histopathology. MATERIALS AND METHODS: Pregnancy and placental reports of all pregnancies complicated by PA (clinically diagnosed) between 11/2008-12/2018 were reviewed. We compared maternal background, pregnancy outcomes, and placental histopathology between cases of PA divided into three groups according to the extent of abruption: Group 1-<30 %, Group 2-30-49 %, and Group 3->50 % of placental surface. Placental lesions were classified according to the current "Amsterdam" criteria. The primary outcome was defined as a composite of severe neonatal morbidity and included ≥ 1 of the following complications: seizures, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, periventricular leukomalacia, blood transfusion, necrotizing enterocolitis, intrauterine fetal demise, or neonatal death. RESULTS: A total of 260 PA cases were included: 111 (42.7 %) in Group 1, 94 (36.2 %) in Group 2, and 55 (21.1 %) in Group 3. The rate of the primary outcome (7.2 % vs. 11.7 % vs. 27.3 %, p = 0.02) was associated with the degree of PA as well as maternal heavy smoking (p = 0.04), DIC (p = 0.03), umbilical artery Ph <7.1 (p = 0.02), 5-minute Apgar scores <7 (p = 0.03), NICU admissions, placental maternal vascular malperfusion lesions (p = 0.04), and neonatal weights <5th percentile (0.04). In multivariable analysis severe adverse neonatal outcome was independently associated with the percentage of PA (aOR = 1.4, 95 % CI = 1.3-3.9). CONCLUSION: The extent of placental abruption, as estimated by the examiner, correlated with DIC and severe neonatal outcomes and may serve as an early alarming sign in deliveries complicated by PA.

RESUMO

INTRODUCTION: Adaptations to pathological intrauterine environment might differ in relation to fetal gender. We aimed to study sex-specific differences in placental pathology of pregnancies complicated by small for gestational age (SGA). METHODS: The medical records and placental histology reports of all neonates with a birth-weight ≤ 10th percentile, born between 24 and 42 weeks of gestation, during 2010-2018, were reviewed. Composite neonatal outcome was defined as one or more of early following complications: neonatal sepsis, blood transfusion, phototherapy, respiratory morbidity, cerebral morbidity, necrotizing enterocolitis, or death. Results were compared between the male and female groups of neonates. Placental lesions were classified into maternal and fetal vascular malperfusion (MVM and FVM) lesions, maternal and fetal inflammatory responses (MIR and FIR), and villitis of unknown etiology (VUE). RESULTS: The male SGA group (n = 380) and the female SGA group (n = 363) did not differ in regard to maternal age, BMI, smoking, associated pregnancy complications, gestational age, and mode of delivery. Neonates in the SGA male group had increased birth-weight and increased respiratory morbidity as compared to the female SGA group (p = 0.007, p = 0.005, respectively). There was no between-group differences in the rate of placental lesions. By multivariate logistic regression analysis, male gender (aOR 1.55, 95% CI 1.05-2.30, p = 0.025), FIR (aOR 4.83, 95% CI 1.07-13.66, p = 0.003), and VUE (aOR 1.89, 95% CI 1.03-3.47, p = 0.04), were found to be independently associated with adverse composite neonatal outcome. DISCUSSION: Male gender as well as placental FIR and VUE are independently associated with adverse neonatal outcome in SGA neonates.

RESUMO

OBJECTIVE: We aimed to compare pregnancy outcomes in association with placental pathology in pregnancies complicated by macrosomia in diabetic vs. non-diabetic women. STUDY DESIGN: Pregnancies complicated by macrosomia (≥4000gr) were included. Pregnancy and delivery characteristics, neonatal outcomes and placental histopathology reports were compared between macrosomia in diabetic [pre-gestational or Gestational Diabetes Mellitus (GDM)] women (diabetic-macrosomia group) vs. non-diabetic women (non-diabetic macrosomia group). Adverse neonatal outcome was defined as ≥1 neonatal complications. Multivariate analysis was used to identify independent associations with adverse neonatal outcome. RESULTS: The diabetic macrosomia group (n = 160) was characterized by higher maternal age (p = 0.002), Body Mass Index (BMI) (p < 0.001), and smoking (p = 0.03), and lower gestational age at delivery (p = 0.001). The diabetic-macrosomia group had higher rates of scheduled Cesarean deliveries (CDs) (58.9 % vs23.7 %,p < 0.001) while the non-diabetic macrosomia group (n = 214) had higher rates of emergent CDs (76.3 % vs.40.7 %,p < 0.001), perineal tears (p = 0.027) and Post Partum Hemorrhage (PPH) (p = 0.006). Placentas from the non-diabetic macrosomia group were characterized by higher rates of maternal and fetal inflammatory response lesions (p < 0.001). Except for higher jaundice rate in the diabetic macrosomia group (p < 0.001), none of the other neonatal outcomes including shoulder dystocia differed between the groups. In multivariate analysis GA < 37 weeks (aOR = 1.4,95 %,CI-1.2-3.9), and emergent CDs (aOR = 1.7,95 %,CI-1.4-4.1) but not diabetes (aOR = 1.1,95 %,CI-0.7-3.9) were associated with adverse neonatal outcome. CONCLUSIONS: Despite major differences in maternal demographics, mode of delivery, maternal morbidity, and placental characteristics- adverse neonatal outcome did not differ between macrosomia in diabetic vs. non-diabetic women and was high in both groups. Clinicians should be aware of the high rate of adverse neonatal outcome in macrosomic fetuses, even in the absence of diabetes mellitus.

RESUMO

OBJECTIVE: We investigated the association between prenatal selective serotonin reuptake inhibitors (SSRI) exposure and pregnancy-outcomes with correlation to placental-histopathology. STUDY DESIGN: Included were pregnancies with maternal SSRI use throughout pregnancy (SSRI-group) and the control group was matched with pregnancies unexposed to SSRI. Placental lesions were classified according to the "Amsterdam" criteria. Adverse neonatal outcome was defined as ≥1 early neonatal-complications. RESULTS: SSRI group had lower birthweights (p < 0.001), higher rates of meconium (p = 0.009), NICU admissions (p < 0.001), and adverse neonatal-outcome (p < 0.001). SSRI placentas had lower birthweight-to-placental-weight ratio (p = 0.02) and higher rates of fetal vascular malperfusion (FVM) lesions (p = 0.03). Using multivariable analyses: GA < 37 weeks (aOR = 2.1, 95%CI 1.7-4.6) and SSRI (aOR = 1.7, 95%CI 1.3-3.9) were independently associated with adverse neonatal outcome while GA < 37 weeks (aOR = 1.6, 95%CI 1.2-3.4), SSRI (aOR = 1.3, 95%CI 1.1-2.6), and smoking (aOR = 1.2, 95%CI 1.1-4.0) were independently associated with FVM lesions. CONCLUSION: SSRI use during pregnancy was independently associated with adverse neonatal outcome and placental FVM.

RESUMO

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age). The main neonatal outcome measures were chorioamnionitis, placental inflammatory grading, first neonatal creatinine value, first neonatal dextrose value, length of neonatal intensive care unit (NICU) stay, necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH) (grades I-IV), blood transfusions, reduced neonatal urine production rate (<4 mL/kg/h), and early neonatal sepsis. Samples of maternal (at admission) and umbilical cord blood were analyzed for interleukin-6 (IL-6) level. RESULTS: The study included 38 women. Low FUPR was associated with clinical chorioamnionitis, longer NICU hospitalization (p = 0.01), higher rates of NEC or IVH (p = 0.008), and blood transfusion (p = 0.004). CONCLUSIONS: A finding of FUPR on in utero ultrasound examination in pregnancies complicated by PPROM may be indicative of adverse neonatal outcome.

RESUMO

INTRODUCTION: High and low birth weight (BW) to placental weight (PW) ratios (BW/PW) have been proposed as markers of placental malfunction. We studied the association of clinical outcome and placental histopathology lesions with BW/PW ratios. MATERIALS AND METHODS: During the period between 2008 and 2013, placentas from deliveries at gestational age (GA) ≥37 weeks, including both complicated and uncomplicated pregnancies, were sent for histopathology evaluation. Maternal and labor characteristics and pathological reports of the high BW/PW ratio group (>90th), normal BW/PW ratio group (10-90), and low BW/PW ratio group were compared (<10th). RESULTS: The BW/PW ratio increased as GA increased, with an average GA of 39.4 ± 1.2 weeks in the normal BW/PW ratio group (p < 0.001). Patients with diabetes mellitus and smokers were more common in the low BW/PW ratio group (p < 0.001). Placental maternal stromal vascular lesions and villitis of unknown etiology (VUE) were more common in the high BW/PW ratio group (p < 0.001 and p = 0.03, respectively). By logistic regression analysis, GA, placental maternal stromal vascular lesions, and VUE were found to be independently associated with a high BW/PW ratio, while diabetes mellitus and smoking were independently associated with a low BW/PW ratio. DISCUSSION: The BW/PW ratio increases significantly beyond 39th weeks, and is associated with an increased rate of placental maternal stromal vascular lesions and VUE.

RESUMO

BACKGROUND: The mechanisms involved in bleeding in cases of placenta previa (PP) and the effect on pregnancy outcome is unclear. OBJECTIVES: We aimed to compare pregnancy outcome and placental histopathology in pregnancies complicated with symptomatic (bleeding) vs. non-symptomatic PP, and to study the effects of the co-existence of histopathological retro-placental hemorrhage (RPH) in cases of symptomatic PP on neonatal and maternal outcomes. STUDY DESIGN: Labor and maternal characteristics, neonatal outcome and placental histopathology lesions of pregnancies with PP, delivered between 24 and 42weeks, during 2009-2015, were reviewed. Results were compared between PP who had elective cesarean delivery (CD) (previa group) and PP with bleeding necessitating emergent CD (symptomatic previa group). Placental lesions were classified to lesions consistent with maternal malperfusion or fetal thrombo-occlusive disease (vascular and villous changes), and inflammatory lesions. RESULTS: Compared to the previa group (n=63), the symptomatic previa group (n=74) was characterized by older patients (p<0.001), higher rate of smokers (p=0.005), thrombophilia (p=0.038), and preterm deliveries (p<0.001). Placentas within the symptomatic previa group were smaller, with higher rates of weight<10th% (p=0.02), RPH (p<0.001) and villous changes related to maternal malperfusion (p=0.023). As compared to symptomatic PP without RPH, co-existence of RPH was associated with higher rate of adverse neonatal outcome (p<0.001) and maternal blood transfusion (p=0.02). On multivariate regression analysis, composite adverse neonatal outcome was found to be dependent on coexisting RPH (OR=2.8, 95%CI 1.2-11.7, p=0.03), and low gestational age (OR=3.1, 95%CI 1.6-4.9, p=0.02). CONCLUSIONS: Symptomatic placenta previa is associated with increased placental malperfusion lesions suggesting an association of maternal malperfusion with abnormal placental separation. The coexisting finding of RPH with symptomatic placenta previa can be seen as a marker for more extensive/severe placental separation, hence the association with maternal transfusion requirements and poorer fetal outcome.

RESUMO

OBJECTIVE: To study the effects of maternal smoking on pregnancy outcome and placental histopathology findings. MATERIALS & METHODS: Maternal and labor characteristics and pathological reports were compared between term placentas of complicated and uncomplicated pregnancies of: heavy smokers (>10 cigarettes per day, H-smokers), moderate smokers (<10 cigarettes per day, M-smokers) and non-smokers (controls, N-smokers). RESULTS: Birth-weights were lower in the H-smokers and M-smokers as compared to the N-smokers (p<0.001), with a higher rate of small for gestational age (SGA): 18.2%, 19.2% and 11.4%, respectively (p=0.01). Deliveries among smokers were characterized by higher rates of abnormal fetal heart rate tracings during labor as compared to non-smokers (p=0.01). Rates of placental maternal and fetal stromal-vascular supply lesions was similar between the groups. CONCLUSIONS: Maternal smoking is associated with higher rates of SGA. Tobacco's potential influence is probably through the disruption of normal placental epigenetic patterns, not expressed in placental histopathology lesions.

RESUMO

Subacute cutaneous lupus erythematosus (SCLE) is a rare eruption related to several pharmacological and chemotherapy agents. We present a 63-year-old female with recurrent epithelial ovarian cancer who developed SCLE after administration of gemcitabine. Following discontinuation of gemcitabine and after oral steroid treatment, all skin lesions disappeared. In view of the extensive use of gemcitabine in recurrent ovarian cancer, it is important to be aware of the possibility of SCLE occurrence in these patients.

RESUMO

OBJECTIVES: We aimed to determine the association of villitis of unknown etiology (VUE) in complicated and uncomplicated pregnancies. METHODS: Placentas from term pregnancies (≥37 weeks) were sent to histopathology evaluation. Maternal and labor characteristics and pathological reports were compared between placentas with VUE (VUE group) and without VUE (controls). Immunohistochemical studies were performed to identify T-cells infiltration in foci of VUE. Placentas were analyzed for concomitant lesions consistent with maternal malperfusion, fetal vascular supply and inflammatory lesions. Small for gestational age (SGA) was defined as birth weight below the 10th %. RESULTS: A total of 1203 placentas were obtained, in which VUE was diagnosed in 5% (n = 60). Compared to controls ((n = 1143), the VUE group was characterized by lower birth weights, p < 0.001, higher rate of SGA, p = 0.009 and lower placental weight, p < 0.001. By logistic regression analysis, after controlling for gestational age, nulliparity, pregnancy complications, obesity, smoking and SGA, only SGA was found to be independently associated with VUE, aOR: 2.3, 95% CI: 1.2-4.4, p = 0.012. Additionally, VUA and maternal malperfusion lesions were found to be independent risk factors for the development SGA. CONCLUSIONS: VUE is associated with lower birth weights, SGA and lower placental weight. Both VUE and maternal malperfusion lesions are risk factors for the development of SGA.

RESUMO

OBJECTIVES: Ultrasound (US) is often used for the work-up of testicular pathology. The findings may implicate on its management. However, there is only scant data on the correlation between US findings and testicular tumor type and size. Herein, we report on a multicenter study, analyzing these correlations. METHODS: The study included patients who underwent orchiectomy between 2000 and 2010. Their charts were reviewed for US echogeneity, lesion size, pathological dimensions, histology, and the presence of calcifications, fibrosis, necrosis and/or intraepithelial neoplasia. The incidence of these parameters in benign versus malignant lesions and seminomatous germ cell tumors (SGCT) versus nonseminomatous germ cell tumors (NSGCT) was statistically compared. RESULTS: Eighty five patients fulfilled the inclusion criteria, 71 malignant (43 SGCT, 28 NSGCT) and 14 benign. Sonographic lesions were at least 20% smaller than the pathologically determined dimensions in 21 (25%) patients. The ability of US in estimating the size of malignant tumors was 71%, compared to 100% of benign tumors (p=0.03), with no significant difference between SGCT and NSGCT. Necrosis was more frequent in malignant tumors (p=0.03); hypoechogeneity and fibrosis were more frequent in SGCT than in NSGCT (p=0.002 and 0.04 respectively). CONCLUSIONS: Testis US of malignant lesions underestimates the size in 25% of the cases, a fact that may impact on the decision of testicular sparing surgery. The ultrasonic lesions were eventually proven to be benign in 16% of the cases. Therefore it is advised to apply frozen sections in borderline cases. Hypoechogeneity is more frequent in SGCT than NSGCT.
