OBJECTIVE To compare the cytophotometric quantitative expression of Ki-67 cellular proliferation factor in the colloid goiter with papillary carcinoma of the thyroid. METHODS The protein Ki-67 was studied with immunohistochemistry in 20 cases of papillary carcinoma of the thyroid and 12 cases of colloid goiter. The immunomarked cell nuclei were quantified through the software SAMBA 4000 and a...

OBJECTIVE To evaluate the diagnostic performance of shear-wave elastography (SWE) for the differential diagnosis of breast papillary lesions. METHODS This study was an institutional review board-approved retrospective study, with a waiver of informed consent. A total of 79 breast papillary lesions in 71 consecutive women underwent ultrasound and SWE prior to biopsy. Ultrasound features and qu...

BACKGROUND Non-glandular papillary carcinoma of the cervix are uncommon tumours. In Uganda where cervical carcinoma is very common, no cases of papillary squamous cell carcinoma of the cervix has been reported. OBJECTIVES To ascertain the occurrence and describe the clinicopathological features of papillary squamous cell carcinoma of the cervix in Uganda. STUDY DESIGN Retrospective review o...

BACKGROUND The cytologic accuracy in assessing malignancy in papillary breast neoplasms (PBNs) is controversial. This is further complicated by overlapping features observed in other breast lesions that produce papillary-like tissue fragments. METHODS The authors reviewed 22 fine-needle aspirates (FNAs) from histologically proven papillary neoplasms: papillary carcinoma (PCA; 10 aspirates) an...

Papillary renal cell tumors (RCT) make up a cytomorphologically and biologically heterogeneous group of kidney cancers including renal cell adenomas (RCA) and renal cell carcinomas (RCC). To find genetic markers landmarking the tumor progression, we have evaluated the genetic alterations obtained by karyotyping, chromosomal and array-CGH and compared with the cytological characteristics and bio...

Understanding how skin microstructure affects slowly adapting type I (SA-I) mechanoreceptors in encoding edge discontinuities is fundamental to understanding our sense of touch. Skin microstructure, in particular papillary ridges, has been thought to contribute to edge and gap sensation. Cauna's 1954 model of touch sensibility describes a functional relationship between papillary ridges and edg...

BACKGROUND The aim of this work was to reveal through sentinel node study the intraoperative presence of preoperatively undetected pathological lymph nodes. MATERIALS AND METHODS At the Surgical Science Department of La Sapienza University of Rome The Authors studied from January 2003 to June 2004 18 patients with papillary carcinoma of the thyroid, who presented no clinical evidence of lymph...

BACKGROUND Idiopathic left ventricular arrhythmias (VAs) and those caused by structural heart disease can originate from the papillary muscles, fascicles, and mitral annulus. Differentiation of these arrhythmias can be challenging because they present with a right bundle branch block morphology by electrocardiography. We sought to identify clinical, electrocardiographic, and electrophysiologica...

The present investigation was carried out on the papillary muscles of ten healthy mature dromedary camels. Anatomically, the papillary muscles are muscular projections from the walls of the right and left ventricles into their cavities. They are processing many nipples like processes. The apex of each muscle process is attached to cord-like tendons; chordae tendineae. The latter, are string-lik...

Low Grade Papillary Nasopharyngeal Adenocarcinoma (LGPAC) is a very rare tumour of mucosal origin compared to a higher incidence of well differentiated keratinized/non-keratinized nasopharyngeal carcinoma. It is an epithelial tumour with glandular differentiation. Its papillary figure seen histologically, is also seen in metastatic papillary thyroid carcinoma. This has caused a significant chal...
