Carcinoma endometrioide sincrónico de ovario y endometrio / Ovarian and endometrial synchronous endometrioid carcinoma

ANTECEDENTES: existe una asociación demostrada entre endometriosis y algunas histologías del carcinoma epitelial de ovario. Por otra parte, se ha observado que hasta un 30% de las neoplasias de ovario se presentan de forma concomitante a neoplasias del endometrio. Para considerar la sincronicidad entre estos tumores, estos deben cumplir criterios anatomopatológicos estrictos como los descritos por scully. OBJETIVO: presentar un caso clínico de carcinoma endometrioide sincrónico de ovario y endometrio sobre focos de endometriosis, así como su diagnóstico y manejo. CASO CLÍNICO: paciente de 27 años que consulta por spotting intermenstrual. En la ecografía endocavitaria se observa un pólipo endometrial. Además, se describe un tumor anexial izquierdo de 42mm, trilobulado, con un polo sólido de 17×15mm. Se somete a una polipectomía histeroscópica y quistectomía ovárica laparoscópica. Asimismo, se reseca implante sospechoso en el fondo de saco posterior. El resultado anatomopatológico de las piezas quirúrgicas fue: pólipo endometrial con hiperplasia compleja con atipias y focos de adenocarcinoma endometrioide grado I; el tumor quístico ovárico izquierdo consistente con quiste endometriósico con focos de adenocarcinoma endometrioide. La lesión peritoneal corresponde a un implante de adenocarcinoma endometrioide grado I. El estudio de las características anatomopatológicas y la presencia del implante peritoneal sugieren el diagnóstico de un carcinoma endometrioide ovárico con origen en una lesión endometriósica sincrónico con un carcinoma endometrioide endometrial. CONCLUSIÓN: el diagnóstico diferencial entre la sincronicidad o diseminación de los tumores de ovario y endometrio de estirpe endometrioide supone un reto para el clínico y es fundamental para el correcto manejo de estas neoplasias.

BACKGROUND: there is a demonstrated association between endometriosis and some epithelial ovarian carcinoma histologies. On the other hand, it has been observed that up to 30% of ovarian neoplasms present concomitantly with endometrial neoplasms. To consider synchronicity between these neoplasms, they must meet strict pathological criteria such as those described by scully. OBJECTIVE: to introduce a case of an ovarian and endometrial synchronous endometrioid carcinoma implanted on endometriosis sites, as well as its diagnosis and management. CLINICAL CASE: a 27-year-old patient who consulted because of an intermenstrual spotting. The ultrasound image showed an endometrial polyp. Furthermore, a 42 mm left adnexal trilobal tumor with a 17×15mm solid pole was described. She underwent a hysteroscopic polypectomy and laparoscopic ovarian cystectomy. Likewise, resection of a suspicious implant in the posterior vaginal fornix was done. The pathological result of the surgical pieces was: endometrial polyp with complex hyperplasia with atypia and focal points of grade I endometrioid adenocarcinoma; the left ovarian cystectomy: endometriotic cyst with focal points of endometrioid adenocarcinoma. The peritoneal lesion corresponded to a grade I endometrioid adenocarcinoma implant. The study of the pathological characteristics and the presence of the peritoneal implant suggest the diagnosis of endometrioid ovarian carcinoma originated in a synchronous endometriotic lesion with endometrial endometrioid carcinoma. CONCLUSION: differential diagnosis between the synchronicity or spread of ovarian and endometrial endometrioid cell line carcinomas, is a great challenge and it is essential for the correct management of these neoplasms

Impact of a CAD system in a screen-film mammography screening program: a prospective study.

OBJECTIVE: The purpose of our study was to perform a prospective assessment of the impact of a CAD system in a screen-film mammography screening program during a period of 3 years. MATERIALS AND METHODS: Our study was carried out on a population of 21,855 asymptomatic women (45-65 years). Mammograms were processed in a CAD system and independently interpreted by one of six radiologists. We analyzed the following parameters: sensitivity of radiologist's interpretation (without and with CAD), detection increase, recall rate and positive predictive value of biopsy, CAD's marks, radiologist's false negatives and comparative analysis of carcinomas detected and non-detected by CAD. RESULTS: Detection rate was 4.3‰. CAD supposed an increase of 0.1‰ in detection rate and 1% in the total number of cases (p<0.005). The impact on recall rate was not significant (0.4%) and PPV of percutaneous biopsy was unchanged by CAD (20.23%). CAD's marks were 2.7 per case and 0.7 per view. Radiologist's false negatives were 13 lesions which were initially considered as CAD's false positives. CONCLUSIONS: CAD supposed a significant increase in detection, without modifications in recall rates and PPV of biopsy. However, better results could have been achieved if radiologists had considered actionable those cases marked by CAD but initially misinterpreted.

Percutaneous microductectomy with a directional vacuum-assisted system guided by ultrasonography for the treatment of breast discharge: experience in 63 cases.

BACKGROUND: Vacuum-assisted devices are becoming a useful tool in the diagnosis and treatment of breast pathology. Recent publications show good results in percutaneous removal of benign lesions. PURPOSE: To discuss our experience in percutaneous excision of ductal lesions with a vacuum-assisted, ultrasound-guided directional system. MATERIAL AND METHODS: From January 2003 to July 2006, 63 patients with pathological nipple discharge and intraductal lesion identifiable on imaging were studied at two reference centers. Percutaneous excision with a vacuum-assisted device was offered as an alternative to surgery. RESULTS: A total of 71 lesions were diagnosed in 63 patients with a mean age of 52 years. All the patients presented nipple discharge. Mammography was normal in 65 cases (92%). Galactography showed an intraductal lesion in 67 cases (94%). Mean lesion size on ultrasonography was 7.4 mm (2-26 mm). Percutaneous excision was performed in 45 lesions (63%), while surgical excision was indicated in 26 lesions. The histopathological results in the 45 lesions biopsied demonstrated intraductal papilloma in 30 cases, dilated duct with papillomatous projections in 11, ductal ectasia with no papillary lesion in three, and a nonspecific benign result in one. Excision was considered complete in 41 lesions (91%). Clinical signs of discharge were resolved in 39 patients (95% of cases treated percutaneously). Mild complications occurred in four cases. CONCLUSION: Percutaneous excision of ductal lesions with an ultrasound-guided, vacuum-assisted device is a safe procedure with high diagnostic and therapeutic value for the management of breast discharge.

Advanced gastric carcinoma with a complete intestinal metaplasia phenotype associated with early intestinal-type carcinoma.

An unusual case of synchronous gastric carcinomas occurred in a 28-year-old man with a family history of gastric disease. Two tumor foci were identified: a well-differentiated advanced carcinoma with the phenotypic properties of complete intestinal metaplasia and an early intestinal-type carcinoma. Histochemical and immunohistochemical stains to demonstrate complete intestinal metaplasia, ie, Alcian blue pH 2.5/periodic acid-Schiff, high iron diamine/Alcian blue pH 2.5, CD10, and MUC2, were all positive in the advanced adenocarcinoma. Of all markers used, only high iron diamine/Alcian blue pH 2.5 and Alcian blue pH 0.5 were positive in the early carcinoma. In these cases, mistakes frequently are made during examination of endoscopic biopsies. Fortunately, the advanced adenocarcinoma was low grade (the patient has shown no signs of disease at 6 years postsurgery). Histopathologic, histochemical, and immunohistochemical findings suggest that an extensive substrate of complete intestinal metaplasia (corpus) and of complete and incomplete intestinal metaplasia (antrum) can be associated with two independent tumors with different phenotypes.
