hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...

Thyroglossal duct cysts are the most frequently encountered congenital neck masses having a malignancy rate of 1%. The most common malignant form is papillary thyroid carcinoma. Synchronous papillary thyroid carcinoma developing in the thyroglossal duct cyst is rarely seen. Synchronized papillary carcinoma can be described as a multifocal tumor or a metastatic lesion on a thyroglossal duct cyst...

Although the hemodynamic effects of diuretics have been studied extensively, their effects on inner medullary blood flow remain unknown. In the present study, renal hemodynamics, including papillary plasma flow measured by the albumin accumulation technique, and associated alterations in papillary tissue solute content were determined in anesthetized, hydropenic dogs and during euvolemic diures...

Background: The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. Methods: From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. Results: The...

INTRODUCTION Papillary breast lesions are rare and constitute less than 10% of benign breast lesions and less than 1% of breast carcinomas. OBJECTIVE To analyse the clinical presentation, preoperative evaluation, and surgical and anatomopathological characteristics of the patients operated on for papillary breast lesions. MATERIAL AND METHODS Retrospective descriptive and analytical study. ...

Intraductal/intracystic papillary carcinoma (IPC) of the breast is defined as a malignant non-invasive papillary tumor arising from the ductal-lobular system. Based on the presence of myoepithelial cells in the cystic wall, IPC is distinguished from encapsulated papillary carcinoma (EPC). Here, we report a case of an intracystic apocrine papillary tumor in the breast of a 49-year-old woman. His...

In this retrospective histologic study, galectin-3 had a sensitivity of 92% (22/24) for papillary thyroid carcinoma and 44% (4/9) for follicular thyroid carcinoma. Thyroid peroxidase (TPO) had a sensitivity of 50% (12/24) for papillary and 11% (1/11) for follicular carcinoma. The combination of galectin-3 and TPO had a sensitivity of 96% (23/24) for papillary and 44% (4/9) for follicular carcin...

AIM The aim of this work was to assess caspase-3 activity in the tissue of papillary thyroid carcinomas of patients and analyze the peculiarities of changes in this activity depending upon a number of pathomorphological and clinical features of tumoral process. METHODS Caspase-3 activity was determined by spectrophotometry with regard to acetyl-asp-glu-val-asp-paranitroanilide. RESULTS At i...

INTRODUCTION Intravascular papillary endothelial hyperplasia is a reactive proliferative lesion of endothelial cells in blood vessels. It typically presents as a painless, reddish purple lesion in the sites affected. The orbit remains an uncommon site of affectation of this relatively common disease. It is noteworthy that this is the first reported case, to the best of our knowledge, of orbital...
