Incidental Diagnosis of a Primary Pure "Mixed" Ovarian Carcinoid: Clinicopathological Report and Concise Review of the Recent Series.

Primary ovarian carcinoid tumors (POCT) are well-differentiated neuroendocrine neoplasms and account for <0.1% of ovarian tumors. POCT usually arise in the context of mature cystic teratoma; however, pure primary ovarian carcinoids without teratomatous or mucinous elements are very rare. We present a case of a 54-year-old woman that underwent total laparoscopic hysterectomy and bilateral salpingo-oophorectomy because of endometrial hyperplasia without atypia. The ovaries were macroscopically normal. Pathology report revealed a primary ovarian carcinoid with mixed trabecular and insular growth patterns. Immunohistochemical was positive for chromogranine A, synaptophysin, and CDX2. The Ki-67 index was <1%. To exclude a metastatic carcinoid to the ovary, a Ga-68 PET/CT was performed. This case highlights the microscopic and immunohistochemical characteristics of pure POCT and potential pitfalls in their differentiation from metastatic carcinoids. In addition, differential characteristics of primary and metastatic ovarian carcinoids are discussed.

ß-Human Chorionic Gonadotropin Dynamics in Early Gestational Events: A Practical and Updated Reappraisal.

In the last decade, the widespread use of transvaginal ultrasound and the availability of highly specific serum assays of human chorionic gonadotropin (hCG) have become mainstays in the evaluation of early pregnancy. These tests have revolutionized the management of pregnancies of unknown location and markedly reduced the morbidity and mortality associated with the misdiagnosis of ectopic pregnancy. However, despite several advances, their misuse and misinterpretations are still common, leading to an increased use of healthcare resources, patient misinformation, and anxiety. This narrative review aims to succinctly summarize the ß-hCG dynamics in early gestation and provide general gynecologists a practical approach to patients with first-trimester symptomatic pregnancy.

Manejo de las lesiones anexiales en el embarazo y actualización del abordaje laparoscópico / Management of adnexal masses in pregnancy and an update of the laparoscopic approach

Resumen El manejo del tumor anexial en embarazadas sigue siendo un desafío. El objetivo del siguiente trabajo es realizar una revisión bibliográfica, en la que se abordarán las diferentes alternativas en cuanto a diagnóstico y manejo del tumor anexial en embarazadas, así como también indicaciones de abordaje quirúrgico y recomendaciones para una cirugía segura. Los tumores anexiales en embarazadas son poco frecuentes, y la mayoría son benignos y tipo funcionales. La ecografía ha sido fundamental para lograr diferenciar su carácter benigno o maligno. El manejo puede ser expectante o quirúrgico. El manejo quirúrgico se reserva para ciertas características de las lesiones anexiales. En cuanto a la vía operatoria, la literatura apoya la laparoscopia mostrando que existen múltiples beneficios al compararla con la laparotomía. Para el abordaje quirúrgico existen opciones en cuanto a la técnica, siendo estas anexectomía o quistectomía. Resulta fundamental tener consideraciones especiales en la técnica debido a los cambios fisiológicos de las embarazadas, como por ejemplo la altura uterina y el tamaño del tumor anexial. A modo de conclusión, el manejo de los tumores anexiales en el embarazo sigue siendo controversial y se extrapola principalmente basándose en la literatura de pacientes no gestantes u otros procedimientos quirúrgicos en embarazadas.

Abstract Nowadays the management of the adnexal tumors in pregnant women is still a challenge. The purpose of this article is to perform a bibliographic review and present the differential diagnosis, management, and surgical approaches for the women in this condition. Adnexal tumors in pregnant women are rare, most of them are benign corresponding to functional cysts. In order to differentiate benign from malignant tumors, Ultrasonography has been one of the most important imaging advances. The management can be either expectant or surgical. Surgical management is referred for tumors with certain specific characteristics. In relation to surgical management, the literature supports laparoscopy, showing greater benefits in comparison to laparotomy. There are different options for this kind of approach. Its mandatory to have special considerations in the technique due to the physiological changes in pregnant women, some examples are the uterine and the tumor size. The management of the adnexal tumors in pregnancy is still controversial, its based on studies of non-pregnant patients or other kinds of surgeries in pregnant women.

Laparoscopic Reverse Technique for Posterior Rectovaginal Deep Endometriosis Nodule Step by Step.

STUDY OBJECTIVE: To demonstrate the application of the so-called reverse technique to approach deep infiltrating endometriosis nodules affecting the retrocervical area, the posterior vaginal fornix, and the anterior rectal wall. In Video 1, the authors describe the complete procedure in 10 steps in order to standardize it and facilitate the comprehension and the reproduction of such a procedure in a simple and safe way. DESIGN: A case report. SETTING: A private hospital in Curitiba, Paraná, Brazil. PATIENT: A 32-year-old woman was referred to our service complaining about cyclic dysmenorrhea, dyspareunia, chronic pelvic pain, and cyclic dyschezia. Transvaginal ultrasound with bowel preparation showed a 2.4-cm endometriotic nodule at the retrocervical area, uterosacral ligaments, posterior vaginal fornix, and anterior rectal wall, infiltrating up to the muscularis 10 cm far from the anal verge. INTERVENTIONS: Not applicable. MEASUREMENTS AND MAIN RESULTS: Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her lower limbs in abduction. Pneumoperitoneum was achieved using a Veress needle placed at the umbilicus. Four trocars were placed according to the French technique as follows: a 10-mm trocar at the umbilicus for the 0 degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions (step 1). The implants located at the ovarian fossae were completely removed (step 2). The ureters were identified bilaterally, and both pararectal fossae were dissected, preserving the hypogastric nerves (step 3). The lesion was separated from the retrocervical area, and the posterior vaginal fornix was resected (reverse technique), leaving the disease attached to the anterior surface of the rectum (step 4). The lesion was shaved off the anterior rectal wall using a harmonic scalpel (step 5). The anterior rectal wall was closed using X-shaped stitches of 3-0 polydioxanone suture in 2 layers (step 6). The specimen was extracted through the vagina (step 7). The posterior vaginal fornix was reattached to the retrocervical area using X-shaped sutures of 0 poliglecaprone 25 (step 8). A pneumatic test was performed to check the integrity of the suture (step 9). At the end of the procedure, hemostasis was controlled, and the abdominal cavity was irrigated using Lactate ringer solution (step10). CONCLUSION: The laparoscopic reverse technique is an alternative approach to face retrocervical or rectovaginal nodules infiltrating the anterior rectal wall. In this technique, the separation of the nodule from the rectal wall is performed at the end of the surgery and not at the beginning as performed within the traditional technique. This enables the surgeon to perform a more precise dissection of the endometriotic nodule from the rectal wall because of the increased mobility of the bowel. The wider range of movements serves as an ergonomic advantage for the subsequent dissection of the lesion from the rectum, allowing the surgeon to decide the best technique to apply for the treatment of the bowel disease (rectal shaving or discoid or segmental resection).

Multidisciplinary laparoscopic management of deep infiltrating endometriosis from 2010 to 2017: A retrospective cohort study. / Manejo laparoscópico multidisciplinario de la endometriosis profunda del 2010 al 2017: estudio de cohorte retrospectivo.

BACKGROUND: Laparoscopy has become the standard of care in the surgical management of deep infiltrating endometriosis (DIE). However, it is a challenging procedure with a high complication rate. Despite the benefits of the minimally invasive approach, DIE resection is often performed by surgeons without adequate training, especially in developing countries like Chile. OBJECTIVE: To asses our experience in the diagnosis and laparoscopic management of DIE during seven years. METHODS: A retrospective cohort study of data including 137 patients with pathology-proven DIE. Surgical and fertility outcomes were evaluated. RESULTS: All procedures were performed laparoscopically without conversion. Dysmenorrhea and dyspareunia were the most common symptoms in 85.4% and 56.9%, respectively. Uterosacral ligaments were the most common DIE location. Endometrioma was present in 48.9% of cases. Median operative time was 140 minutes; however, it was longer in cases requiring bowel surgery (p < 0.0001). The complication rate was 10.9%. Median follow-up was 24.5 months. The pregnancy rate was 58.1% and 90% of patients reported significant symptom relief after surgery. CONCLUSION: Laparoscopic surgical management of DIE is effective and safe but it must be performed in tertiary centers with the availability of multidisciplinary teams.

INTRODUCCIÓN: La laparoscopía es actualmente el estándar en el manejo de la endometriosis profunda. Sin embargo, requiere de un entrenamiento específico e involucra la realización de procedimientos complejos y asociados a una alta tasa de complicaciones. Por lo anterior en Chile y Latinoamérica, la endometriosis profunda es frecuentemente manejada de manera inadecuada. OBJETIVO: Describir nuestra experiencia en el enfrentamiento clínico y manejo quirúrgico laparoscópico de la endometriosis profunda, durante los últimos siete años. MÉTODOS: Estudio de cohorte retrospectivo de 137 pacientes consecutivas operadas y con confirmación histológica de endometriosis profunda. Se recolectaron los datos demográficos, datos quirúrgicos, complicaciones, resultados reproductivos y seguimiento. RESULTADOS: Todas las cirugías fueron completadas por laparoscopía, sin conversión. La dismenorrea y la dispareunia fueron los síntomas más frecuentes en 85,4 y 56,9%, respectivamente. La localización más frecuente de endometriosis profunda fueron los ligamentos úterosacros, coexistiendo un endometrioma en 48,9% de los casos. La mediana de tiempo operatorio fue de 140 minutos, siendo significativamente más prolongado en casos con compromiso intestinal (p < 0,0001). Quince pacientes (10,9%) presentaron complicaciones. El seguimiento medio fue de 24,5 meses. La tasa de embarazo fue de 58,1% y 90% de las pacientes reportó una mejoría significativa de su sintomatología. CONCLUSIONES: El manejo laparoscópico de la endometriosis profunda es efectivo y seguro, pero debe reservarse a centros especializados y con disponibilidad de equipo multidisciplinario.

Ovarian Torsion after Hysterectomy: Case Report and Concise Review of the Reported Cases.

Ovarian torsion after hysterectomy is a rare event. The diagnosis of ovarian torsion is challenging because symptoms are nonspecific. We present a case of ovarian torsion 2 years after laparoscopic hysterectomy (LH). Furthermore, we performed a literature review about ovarian torsion after hysterectomy. This case shows that, in cases of acute onset pelvic pain in patients with history of hysterectomy, the adnexal torsion must be kept in mind in the differential diagnosis, especially in those women who had undergone LH.

Thoracic and diaphragmatic endometriosis: Single-institution experience using novel, broadened diagnostic criteria

Objective: To describe our experience with the multidisciplinary management of both thoracic/diaphragmatic endometriosis (TED), applying a broadened definition of the "Thoracic endometriosis syndrome (TES)" to define cases. Material and Methods: We present a retrospective series of consecutive patients affected by pathology-proven TED, treated at our institution, during a period of 7 years. Results: Five women were included. Two patients were referred due to catamenial chest/shoulder pain, one due to recurrent catamenial pneumothorax, and one due to new-onset diaphragmatic hernia. One patient had no thoracic symptoms, but diaphragmatic endometriosis was found during gynecologic laparoscopy for pelvic endometriosis. Endometriosis was histologically confirmed in all cases. After follow-up, all patients remain asymptomatic. Conclusion: Broadened TES criteria could increase the incidence of TED and determine better knowledge of this condition. Multidisciplinary, minimally invasive surgery is effective and safe, but should be reserved for tertiary referral centers.

Educational value of an intensive and structured interval practice laparoscopic training course for residents in obstetrics and gynecology: a four-year prospective, multi-institutional recruitment study.

OBJECTIVE: To assess the educational value of an ongoing interval practice laparoscopy training program among obstetrics and gynecology residents. DESIGN: Prospective cohort, multi-institutional recruitment study. We conducted structured laparoscopic training sessions for residents, using both inanimate and porcine models. The 6-day course was separated into two 3-day long modules conducted 2 months apart. A prospective evaluation of standardized tasks was performed using validated scales. Resident's performance was compared using the Student t test and Wilcoxon signed-rank test when appropriate. SETTING: International Center of Endoscopic Surgery (CICE), Clermont-Ferrand, France. PARTICIPANTS: 191 PGY2 or PGY3 residents from different institutions. RESULTS: Significant improvement in time and technical scores for both laparoscopic suturing and porcine nephrectomy was noted (p < 0.0001). After 2 months, we found no improvement in suturing time (p = 0.59) or technical scores (p = 0.62), and significant technical deterioration was observed for the right hand (p = 0.02). Porcine nephrectomy improvement remained significant after 2 months (p < 0.0001). CONCLUSIONS: Despite significant short-term educational value of interval practice in laparoscopic performance, some acquired skills seem to deteriorate faster than anticipated.

Learning experience using the double-console da Vinci surgical system in gynecology: a prospective cohort study in a University hospital.

PURPOSE: To report our preliminary experience with robotic-assisted laparoscopy in a variety of gynecological surgeries in a teaching hospital. METHOD: A total of 33 patients who underwent robotic-assisted laparoscopic procedures for gynecological diseases were included in the study. All surgeries were performed using the double-console da Vinci surgical system. Patient's demographics, surgical procedures, operative time, perioperative complications, conversion rate, hospital stay and estimated blood loss were prospectively collected. RESULTS: All procedures were completed robotically except three (9%): two cases were converted to laparotomy and one case was converted to vaginal surgery. The mean age was 47 ± 11 and mean BMI was 23 kg/m². Mean time taken for docking the robot was 22 min. Mean operative time was 152 min. Mean anesthesia time was 196 min. Mean hemoglobin drop was 2 g/dL. Four complications occurred: one transitory ischemic attack, one port-site hernia managed through trocar incision, one periumbilical hematoma managed conservatively and one vaginal cuff hematoma who required laparoscopy. The mean hospital stay was 4 days. CONCLUSION: With the use of robotic technology, surgeons are able to offer minimally invasive surgery to a larger percentage of patients. Double console system seems a promising tool in surgical education, improving both resident training and participation in surgeries. A shorter adaption to robotics could be expected in teams with previous experience with standard laparoscopy, however, a stepwise start with simpler cases is the key to achieve a safe adaption to robotic surgery.

Long-term follow-up after laparoscopic management of endometrial cancer in the obese: a fifteen-year cohort study.

STUDY OBJECTIVE: To assess the surgical outcomes and long-term results of laparoscopic treatment of endometrial cancer in obese patients, and compare these results with those of nonobese women. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Two referral cancer centers. PATIENTS: Fifty-two obese and 155 nonobese women with clinical stage I endometrial cancer managed by laparoscopy from 1990-2005 in two referral centers. INTERVENTIONS: Demographic, surgical, perioperative and pathological characteristics of obese women and nonobese women with endometrial cancer treated by laparoscopy were analyzed and then compared. Recurrence-free and overall survival was calculated by use of Kaplan-Meier method. MEASUREMENTS AND MAIN RESULTS: Median BMI of the study population was 26.2 Kg/m(2). Median BMI among obese patients was 34.2 Kg/m(2). The conversion rate was independent from the BMI of the patient (3.8% vs 4.5%, p = .80). Neither mean operative time (187.5 vs 172 min, p = .11) neither hospital stay (5.2 vs 4.9 days, p = .44) were related with BMI. Lymphadenectomy was considered not feasible in 7 obese (17%) and 8 nonobese (7%) women (p = 0.09). Fewer lymph nodes were retrieved among obese women (8 versus 11, p <.0002). No differences were found between the groups in terms of perioperative complications. Median follow-up was 69 and 71 months for the obese and nonobese, respectively (p = .59). Overall and disease-free 5-year survival rates did not differ between obese and nonobese patients (90.3% and 87.5% versus 88.5% and 89.8%, respectively). CONCLUSION: Despite some limitations, the laparoscopic approach seems to be particularly useful for obese patients with endometrial cancer, with similar survival and recurrence rates and without any more complications compared to the nonobese population.

Laparoscopic implantation of neural electrodes on pelvic nerves: an experimental study on the obturator nerve in a chronic minipig model.

BACKGROUND: Laparoscopic exposure of pelvic nerves has opened a new area in the field of neuromodulation. However, electrode design and material deterioration remain issues that limit clinical application. The objective of this study was to evaluate experimentally the laparoscopic implantation of different types of neural electrodes in order to achieve functional and selective electrical stimulation of pelvic nerves. METHODS: This was a prospective comparative study of the laparoscopic implantation and tolerance and efficacy of three monopolar cuff electrodes implanted on the obturator nerve in ten Göttingen minipigs (18-20 months old; 14.5-24 kg body weight). Animals were allocated to two groups. A 3-mm-diameter laparoscopic instrument was used during dissection of paravesical fossa and obturator nerve on both sides in order to minimize nerve damage. In all animals, a "split-cylinder" cuff electrode was implanted around the left obturator nerve. On the right side, a "lasso" cuff electrode was implanted in the first group and a "closed-cylinder" cuff was implanted in the second group. Electrical stimulation (0-5 V, 20 Hz) was performed for implanted electrodes on days 0, 7, 15, 30, 45, 60, and 90. Current intensity thresholds were identified by palpation of muscle contraction. Strength developed according to stimulation level and was measured using weight transducers. RESULTS: All procedures were performed by laparoscopy. Mean operative times differed significantly among groups, the shortest being for split-cylinder electrodes (P = 0.0002). No electrical spread phenomena were observed. Initial thresholds were below 1.5 V (range = 0.5-1.3); however, a significant rise was observed, with time to a maximum of 2.7 V (P < 0.0001). Only split-cylinder electrodes remained functional after 3 months. The mean value of maximum strength remained stable during the study period (P = 0.21, NS). CONCLUSIONS: The laparoscopic approach to implanting neuroprostheses seems to be very attractive. Furthermore, this approach could allow highly selective nerve stimulation to be achieved using simpler devices such as split-cylinder monopolar electrodes.

Proximal ectopic pregnancy: a descriptive general population-based study and results of different management options in 86 cases.

OBJECTIVE: To describe different approaches for diagnosis and management of proximal ectopic pregnancies (PP) in general population. DESIGN: Observational population based-study. SETTING: Regional ectopic pregnancy registry. PATIENT(S): Eighty-six PP registered from 1992 to 2008. INTERVENTION(S): Surgical (radical or conservative), medical, or combined therapies. MAIN OUTCOME MEASURE(S): Epidemiologic characteristics, clinical presentation, hCG level, treatments performed, failure rate, and recurrence. RESULT(S): Mean gestational age was 48.2 days. Estimated incidence of PP was 2.7%. Abdominal pain and vaginal bleeding were the commonest symptoms. Two patients were admitted in hypovolemic shock. Diagnostic modalities included transvaginal ultrasound, abdominal ultrasonography, and laparoscopy in 38 (44%), 7 (8%), and 39 (45%) cases, respectively. Mean hCG level was 10,759 IU/L. Thirty-four patients underwent primary cornual resection (39.5%) by laparoscopy (n = 32) or laparotomy (n = 2). Twenty-seven patients (31.4%) underwent primary conservative surgery by laparoscopy: cornuostomy (n = 18) or extended salpigostomy (n = 9). Primary medical treatment with methotrexate was attempted in 14 patients (16.3%). Expectant management was attempted in one case (1.2%). Eleven cases received combined therapies (11.6%). Failure rates for medical and surgical treatments were 35.7% and 28%, respectively. No failures were noted among patients who received combined therapies. CONCLUSION(S): Proximal ectopic pregnancy remains a life-threatening condition. Diagnosis is challenging and requires a high index of suspicion. Despite available conservative strategies, management of PP remains heterogeneous.

Predictive factors of failure in management of ectopic pregnancy with single-dose methotrexate: a general population-based analysis from the Auvergne Register, France.

In a general population setting, the existence of a learning curve for treatment of ectopic pregnancy with single-dose methotrexate has been demonstrated, because a significant decrease in failure rate can be achieved over time. Despite this finding, the risk of single-dose methotrexate failure increases significantly in patients with initial hCG levels>1,300 IU/L and/or in women who report having ever used combined oral contraception before pregnancy.

Predicting success of laparoscopic salpingostomy for ectopic pregnancy.

OBJECTIVE: To estimate predictive factors for failure of laparoscopic conservative treatment of ectopic pregnancy using a standardized surgical technique. METHODS: We performed a population-based study from the Auvergne ectopic pregnancy registry. A total of 3,196 cases of ectopic pregnancy were registered between 1992 and 2008. Among conservative treatments (n=1,965), 1,306 (66.5%) patients underwent laparoscopic salpingostomy exclusively. For each case, collected data included: sociodemographic characteristics, previous surgeries, gynecologic and reproductive histories, conditions of conception, Chlamydiae trachomatis serology, human chorionic gonadotropin (hCG) levels, and ectopic pregnancy characteristics. Univariable and multivariable analyses were performed to identify risk factors for treatment. A receiver operating characteristic curve was also provided. Statistical significance was established at P<.05. RESULTS: We identified 86 treatment failures (6.6%). The failure rate remained stable through the study period. Pretherapeutic hCG level was the only factor significantly associated with treatment failure. Patients with an hCG level of at least 1,960 international units/L had a failure rate of 8.6% compared with 5.1% in patients with a lower hCG level (P=.03). Sensitivity and specificity of this cutoff limit were 47% and 67%, respectively (likelihood ratio(+)=1.4 and likelihood ratio(-)=0.8). CONCLUSION: The hCG level of at least 1,960 international units/L is the only factor related to treatment failure. However, the prognostic value of this cutoff is low and with limited clinical relevance. LEVEL OF EVIDENCE: II.

"Iatrogenic" parasitic myomas: unusual late complication of laparoscopic morcellation procedures.

STUDY OBJECTIVE: To describe our experience in diagnosing and managing parasitic myomas developing as an unexpected late complication of laparoscopic morcellation. DESIGN: Observational study (Canadian Task Force classification II-3). SETTING: University hospital. PATIENTS: Retrospective chart review of all patients found to have parasitic myomas that developed after previous morcellation. INTERVENTION: Laparoscopic morcellation. Review of the recent literature correlated with clinical, surgical, and pathologic features of our cases. MEASUREMENTS AND MAIN RESULTS: Four patients had heterogeneous pelvic masses after morcellation. In 3 patients, symptoms developed between 2 and 16 years after the primary surgery. One patient had no symptoms, and was referred because of a suspect pelvic mass. Vaginal examination revealed painful pelvic masses in the pouch of Douglas in 2 patients, and painless masses fixed to the vaginal vault and anterior vaginal wall, respectively, in the other 2 patients. Laparoscopic examination confirmed the presence of parasitic masses in 3 patients. In 1 patient, the mass was excised vaginally. Histologic analysis confirmed leiomyoma fragments in all patients. A well-differentiated endometrial carcinoma was incidentally found in 1 patient after hysterectomy. CONCLUSION: These masses probably resulted from growth of missed fragments of uterine tissue after previous morcellation, culminating in development of symptomatic iatrogenic parasitic myomas. If morcellation is anticipated or required, exclusion of malignancy is mandatory. Meticulous inspection of the abdominal cavity is necessary after morcellation. In patients with a history of morcellation who have pelvic masses, iatrogenic parasitic myomas should be considered in the differential diagnosis.

Tumores de glándulas salivales: hallazgos histopatológicos en 168 pacientes / Salivary gland tumors: histopathological findings in 168 patients

Introducción : La clasificación y gradación histológica de los tumores de glándulas salivales ha cambiado en los últimos años. La variedad y grado histológico son actualmente factores pronósticos independientes. Objetivo: Presentar los hallazgos histopatológicos en pacientes tratados en el Instituto Nacional del Cáncer de Santiago (INC) por tumores de glándulas salivales, en los últimos 12 años. Material y Métodos: Se revisaron retrospectivamente los registros clínicos de 168 pacientes atendidos en el INC ente enero 1992 y marzo 2004. Las biopsias fueron revisadas en la unidad de Anatomía Patológica de INC. Se registró edad, género, localización e histología. Resultados: La edad media del grupo (87 mujeres, 81 hombres) fue 54 años. Al diagnóstico, la edad media fue 51 años en pacientes con tumores benignos y 58 en aquellos con cáncer. El 75 por ciento (126 pacientes) correspondió a tumores paratídeos, 16 por ciento (26 pacientes) a tumores submandibulares, 8 por ciento (14 pacientes) a tumores de glándulas salivales menores y 1 por ciento (2 pacientes) a tumores sublinguales. Entre los tumores benignos, la variedad más frecuente fue el adenoma pleomorfo y la mayoría se localizó en la parótida. Entre los cánceres, en carcinoma adenoídeo-quístico fue la variedad predominante y se localizó mayoritariamente en la glándula submandibular y glándulas salivales menores. Conclusión: Aunque la patología benigna es mucho más frecuente, sobre todo en la glándula parótida, el riesgo de malignidad es aún elevado, sobre todo en pacientes mayores de sexo masculino.

[Splenic artery aneurysm: case report]. / Aneurisma de la arteria esplénica: diagnóstico diferencial y alternativas terapéuticas.

Splenic artery aneurysms are rare and occur predominantly in women. Most of them are asymptomatic until rupture. We report a previously healthy 73 year-old woman who presented with non specific symptoms: dyspepsia and constipation. Laboratory tests were normal. Subsequent examinations (ultrasound and CT) showed a large aneurysm of the splenic artery without any sign of rupture. Endovascular treatment remained successfully performed using coil embolization. During a 12-months follow-up period, the patient was asymptomatic and no evidences of complications or splenic infarction were observed on CT scans.
