OBJECTIVE We previously reported the results achieved in detecting sentinel lymph nodes (SLN). We applied the molecular techniques (RT-PCR) to improve the detection of micrometastasis in order to evaluate an improvement of staging in early non-small cell lung cancer (NSCLC) patients (pts). METHODS This study was carried out on 22 consecutive NSCLC pts with stage I disease. A dose of 37MBq (1 ...

BACKGROUND Both Helicobacter pylori and gastro-oesophageal reflux disease (GORD) may cause inflammation in cardiac mucosa. Intestinal metaplasia (IM) is found more often in GORD associated inflammation than in inflammation caused by H pylori, especially in young individuals. AIM To examine morphological differences in chronic inflammation in these two conditions by immunohistochemistry. PAT...

Mature pepper (Capsicum sp.) fruits come in a variety of colors, including red, orange, yellow, brown, and white. To better understand the genetic and regulatory relationships between the yellow fruit phenotype and the capsanthin-capsorubin synthase gene (Ccs), we examined 156 Capsicum varieties, most of which were collected from Northwest Chinese landraces. A new ccs variant was identified in ...

CONTEXT Distinction of medullary carcinoma of the large intestine from other cytokeratin (CK) 7⁻/CK20⁻ carcinomas can be challenging when working on a tumor of unknown primary because the majority of medullary carcinomas are negative for CK7, CK20, and CDX2. OBJECTIVE To investigate the expression of cadherin-17 and SATB-2 and other markers in medullary carcinomas of the large intestine and c...

AIMS High-grade, poorly differentiated, infiltrative carcinomas involving the renal sinus region often pose challenging differential diagnostic considerations, specifically differentiation of urothelial carcinoma (UC) from renal cell carcinoma (RCC) subtypes. Accurate classification, especially the distinction of UC from RCC, is critical, as therapeutic approaches differ. METHODS AND RESULTS ...

BACKGROUND Scapular bronchogenic cyst (SBC) is rare. METHODS A sinus on a boy's left scapula was excised. RESULTS Histopathological analysis showed the epithelium with scattered PAS-positive goblet cells was positive for CEA and CK7. CONCLUSION SBC should be suspected of a superficial scapular skin lesion in children.

BACKGROUND Adenoid basal carcinoma (ABC) of uterine cervix is an extraordinary example of carcinoma with both basal and glandular cell types. Here we present such a case of ABC combined with invasive squamous cell carcinoma (SCC) of 55-year-old woman. METHODS The tumor was stained with Hematoxylin-Eosin (HE), Mucicarmine, PAS/Alcian Blue, CK AE1/AE3, CK7, CD117 and Ki67. RESULTS The whitish...

AIMS Pathologists are under increasing pressure to accurately subclassify sarcomas, yet neuropathologists have limited collective experience with rare sarcoma types such as synovial sarcoma. We reviewed 9 synovial sarcomas affecting peripheral nerve diagnosed by neuropathologists and explored the morphologic and immunohistochemical differences between these and MPNST. Our goal was to make pract...

PURPOSE To investigate expression of muscarinic, cholinergic, and adrenergic receptors on developing conjunctival goblet cells. METHODS Eyes were removed from rats 9 to 60 days old, fixed, and used for microscopy. For glycoconjugate expression, sections were stained with Alcian blue/periodic acid-Schiffs reagent (AB/PAS) and with the lectins Ulex europeus agglutinin I (UEA-I) and Helix pomati...
