From August 2010 to June 2011, 10 consecutive patients underwent transvaginal NOTES of the adnexa, including tubal sterilization in 3, salpingectomy because of ectopic pregnancy in 3, and ovarian tumor enucleation in 4. The mean (SD; 95% CI) age of the patients was 34.8 (9.7; 27.9-41.8) years, and their body mass index was 21.6 (2.8; 19.4-23.8). In 9 of the(More)
OBJECTIVE The specific 30-bp deletion of the Epstein-Barr virus (EBV)-derived latent membrane protein-1 gene has been suggested to be associated with the pathogenesis of nasopharyngeal carcinoma (NPC) and a more aggressive phenotype of some EBV-associated malignancies. METHODS The authors conducted a retrospective cohort study. Between 1995 and 2001, 542(More)
To analyse the accuracy of dual-energy contrast-enhanced spectral mammography in dense breasts in comparison with contrast-enhanced subtracted mammography (CESM) and conventional mammography (Mx). CESM cases of dense breasts with histological proof were evaluated in the present study. Four radiologists with varying experience in mammography interpretation(More)
CONTEXT Interpretation of papillary lesions of the breast remains a challenging task because of the wide morphologic spectrum encountered in the benign, atypical, and malignant subtypes. Data on clinical significance and outcome of papillary lesions, with superimposed atypia or areas similar to ductal carcinoma in situ partially replacing the benign(More)
Primary ovarian malignant melanomas are extremely rare. The wide range of morphologic appearances assumed by melanomas in the ovary can cause considerable difficulty in diagnosis. The clinicopathologic features of 4 definite and 1 probable primary ovarian melanomas are presented. The patients ranged in age from 41 to 71 years. Four tumors were within(More)
Primary angiosarcoma of the spleen is a very rare and aggressive neoplasm with poor prognosis. Splenic angiosarcoma rarely occurs in the pediatric group (18 years or younger). Survival duration for pediatric patients is very limited. We report a 7-year-old boy with splenic angiosarcoma presented with left upper quadrant abdominal pain and a palpable(More)
OBJECTIVE We investigated the differences of dynamic enhanced values between the locally advanced breast cancers with and without axillary nodal metastasis on computed tomography (CT) after neoadjuvant chemotherapy. METHODS The patients with locally advanced breast cancer (greatest diameter >5 cm before chemotherapy) who completed the preoperative(More)
PURPOSE To compare the diagnostic accuracy of contrast-enhanced (CE) magnetic resonance imaging (MRI) and diffusion-weighted MRI (DWI) in the differentiation between uterine leiomyosarcoma (LMS) / smooth muscle tumor with uncertain malignant potential (STUMP) and benign leiomyoma. MATERIALS AND METHODS A consecutive cohort of 8 LMS/STUMP and 25 benign(More)
A 40-year-old woman, gravida 2, para 2, with squamous cell carcinoma of the cervix, stage IIB, underwent ovarian transposition. Bilateral salpingectomy was performed as part of the operative technique. Histopathologic analysis revealed mucosal spread of the tumor to one of the fallopian tubes. The patient underwent radiation of the ovaries in their new(More)
OBJECTIVES The aim of this study was to investigate the feasibility of molecular diagnosis of nasopharyngeal carcinoma (NPC) by combining nasopharyngeal swab and polymerase chain reaction (PCR) to detect Epstein-Barr virus (EBV) derived latent membrane protein-1 gene (LMP-1) and Epstein-Barr nuclear antigen gene (EBNA). METHODS 437 adults underwent(More)
