Accuracy of lymph nodes cell block preparation according to ultrasound features in preoperative staging of breast cancer

DIAGNOSTIC CYTOPATHOLOGY, Issue 1 2010
Corinne Engohan-Aloghe M.D.
Abstract To analyse the correlation between axillary ultrasonography (US), cell block (CBs) preparation, and histological diagnosis of lymph nodes from patients with primary breast cancer with the intention to assess the accuracy of cell block (CB) technique in preoperative staging. We tested a series of 26 patients who underwent axillary cell blocks from ultrasound guided fine-needle aspiration with histologic follow-up (axillary lymph nodes dissection). The specificity of axillary cell block was 100% vs. 14% for axillary ultrasound and the sensitivity was 73% for axillary cell block and 87% for axillary ultrasound. The positive and negative predictive values of cell block were respectively, 100 and 78%. Based on these results, we concluded that CB preparation was a feasible and specific technique to evaluate axillary lymph nodes status of patients with primary invasive breast cancer. Diagn.

Spontaneous rupture of non-parasitic hepatic cyst

INTERNATIONAL JOURNAL OF CLINICAL PRACTICE, Issue 1 2006
G. Poggi
Summary Intrahepatic cysts are generally classified as congenital, traumatic, infectious or neoplastic. Non-parasitic hepatic cysts (NPHCs) include simple cysts and adult polycystic liver disease in which the liver is diffusely occupied by cysts. NPHCs usually reach a large size before causing symptoms, unless a complication such as rupture, bleeding, infection, obstructive jaundice or neoplastic transformation occurs. We report the case of a 67-year-old man with spontaneous rupture of simple liver cyst. The clinical pictures and the unusual ultrasound features of this rare condition are discussed. [source]

Prader-Willi syndrome: is there a recognizable fetal phenotype?

PRENATAL DIAGNOSIS, Issue 9 2008
Nicole Bigi
Abstract Objectives To determine fetal features, which could lead to the diagnosis of Prader-Willi syndrome (PWS) during pregnancy. Methods We analyze the ultrasound features, genetic studies and pathologic findings in two cases of PWS diagnosed during pregnancy. Results In the first case, diminished fetal movement, polyhydramnios and oddly positioned hands and feet suggested PWS. Methylation studies confirmed diagnosis and a deletion was detected in the 15q11-q13 region. In the second case, similar ultrasound findings led to prenatal diagnosis of PWS with an abnormal methylation pattern compatible with uniparental disomy. Both fetuses had a characteristic appearance at 28 and 30 weeks' gestation, which included a peculiar position of hands with flexed wrists and dorsi-extended feet with flexed toes. Conclusions The peculiar position of the extremities combined with diminished fetal movement and polyhydramnios seems to be characteristic and should suggest PWS.
