An immunocytochemical method for fixed and paraffin-embedded human breast biopsies is reported for the detection of myoepithelial and epithelial cells using antibodies to myosin and keratin, respectively, and of basement membranes using antibodies to laminin and type IV collagen. Using these markers, myoepithelial cells can be clearly distinguished in the normal breast and in the benign breast ...

A sinister and stealthy marauder, infiltrating lobular carcinoma (ILC) can potentially elude detection due to its pathologic appearance. As reviewed in the last issue of The WCC Note, the shape of ILC at pathology varies. It ranges from tumors with irregular margins; to those displaying diffuse invasion with cells infiltrating single file or loosely associated; to variants with large groups of ...

BACKGROUND NIN/RPN Binding protein 1 homologue (NOBp1), encoded by NOB1 gene, was reported to play an essential role in the oncogenesis and prognosis of carcinomas. We conducted a study to reveal its expression and clinical significance in breast infiltrating ductal carcinoma. METHODS To explore the relationship between NOB1 expression and the clinical TNM (cTNM), 162 patients who undergone s...

The biological characteristics of supraglottic carcinoma was studied with special reference to the correlations of various biological factors with the prognosis of the lesion. The study included 100 cases of supraglottic carcinoma treated by total laryngectomy in the First Hospital of China Medical University in the period from 1975 to 1978, and 7 factors including histopathological findings ob...

We present a patient with a history of infiltrating lobular breast carcinoma that metastasized to both the biliary and urinary tract after a ten year disease-free period following mastectomy and chemoradiotherapy. The patient presented with acute cholecystitis; imaging and histopathology revealed infiltrating lobular carcinoma of the gallbladder and urinary bladder. This report emphasizes the i...

OBJECTIVE Signet ring carcinoma of the stomach is well known to be more aggressive and infiltrating than adenocarcinoma. Different studies have proposed that signet ring cell carcinoma would be more infiltrating because of the loss of E-cadherin expression, this cadherin is a class of protein cell membrane protein which plays an important role in cell-adhesion. METHODS We carried out a transv...

We report a case of granulocyte-colony stimulating factor (G-CSF) producing infiltrating urothelial carcinoma of the left renal pelvis. The patient was referred to our hospital for fever and anorexia. Blood tests showed elevated level of leukocytosis without any infectious diseases. The serum concentration of G-CSF was remarkably elevated. Abdominal computed tomography (CT) revealed a huge mass...

Objective: To evaluate programmed death-ligand 1 immunohistochemical expression in the available variants of urinary bladder carcinoma, and to correlate its with clinicopathological features.Method: The retrospective study was conducted at Faculty Medicine, Kafrelsheikh University, Egypt, from February 2020 April 2021, comprised formalin-fixed paraffin-embedded specimens carcinoma belonging pat...
