This case report describes a 75 year old man who had a renal papillary carcinoma associated with a low grade tumour of the collecting ducts. These tumours showed diVerent immunohistochemical patterns for epithelial membrane antigen, cytokeratin 19, and Ulex europaeus lectin expression. In addition, cytogenetic findings were 47, XY, +7 <7> and 45, XY, −8, add(12)(q–ter)<10> for the papillary ren...

Previously, we found that treatment of cutaneous wounds with Atropa belladonna L. (AB) revealed shortened process of acute inflammation as well as increased tensile strength and collagen deposition in healing skin wounds (Gál et al. 2009). To better understand AB effect on skin wound healing male Sprague-Dawley rats were submitted to one round full thickness skin wound on the back. In two exper...

This study was undertaken to evaluate keratin 19 (K19) as a biochemical marker for skin stem cells in order to address some long standing questions concerning these cells in the field of cutaneous biology. We first used the well-established mouse model enabling us to identify skin stem cells as [3H]thymidine-label-retaining cells. A site directed antibody was raised against a synthetic peptide ...

This case report describes a 75 year old man who had a renal papillary carcinoma associated with a low grade tumour of the collecting ducts. These tumours showed different immunohistochemical patterns for epithelial membrane antigen, cytokeratin 19, and Ulex europaeus lectin expression. In addition, cytogenetic findings were 47, XY, +7 <7> and 45, XY, -8, add(12)(q-ter)<10> for the papillary re...

Detection of circulating tumor cells and micrometastases in patients with cancer should prove useful in determining prognosis and in planning and monitoring systemic therapies. We have developed immunomagnetic isolation of carcinoma cells followed by reverse transcription polymerase chain reaction (immunobead RT-PCR) as a method for identifying very small numbers of breast cancer cells in blood...

The case of a 14-year-old mongrel dog with a thyroid tumor treated by thyreoidectomy is described. The resected tumor was subjected to a detailed morphological and immunohistochemical analysis utilizing antibodies directed against thyroglobulin, calcitonin, chromogranin A, cytokeratin 19, thyroid transcription factor-1, CD31, Ki-67 and minichromosome maintenance protein 3. Expression level of t...

Combined immunostaining with galectin-3, fibronectin-1, CITED-1, Hector Battifora mesothelial-1, cytokeratin-19, peroxisome proliferator-activated receptor-g, and sodium/iodide symporter antibodies for the differential diagnosis of non-medullary thyroid carcinoma Ying Y Liu, Hans Morreau, Job Kievit, Johannes A Romijn, Nancy Carrasco and Johannes W Smit Department of Endocrinology, C4-R, Leiden...

AIM The aim of this study was to make immunohistochemical analyses with Inhibin alpha-subunit, Melan A and MNF116 (pan-Cytokeratin antibody) in pheochromocytomas, because immunohistochemistry is useful for the distinction between adrenal tumors. PATIENTS AND METHODS We used 20 patients with pheochromocytomas submitted to laparoscopic (n=19) or classical (n=1) surgery and we have explored immu...

Background: Low-grade oncocytic tumour (LOT) is an emerging entity describing a slow growing with morphologic features overlapping between chromophobe renal cell carcinoma (ChRCC) and oncocytoma, staining positive for cytokeratin-7 negative CD117 (c-kit). This has been recently recognised in the WHO classification of tumours 5th edition 2022. Presentation: In this case report, we present 77-yea...

We compared the significance of several serum markers to evaluate the activity of Pneumocystis carinii pneumonia (PCP) in an immunocompromised patient. We successively measured KL-6, an amino-terminal propeptide of Type III procollagen (PIIINP), and the cytokeratin 19 fragment (CK19) in the sera of a patient with PCP. Interestingly, PIIINP, KL-6, and CK19 levels in the sera did not increase at ...
