background: squamous cell carcinoma (scc) is the most common malignancy in oral cavity. angiogenesis is essential for the development and progression of scc. recently, some studies have reported that mast cells may play a role in tumor progression via promoting angiognesis. since the results of various studies on the role of mast cells in tumor progression is not uniform, the aim of this study ...

malignant tumors of pancreas are usually primary neoplasms and pancreatic metastases are rare findings. we are reporting a case of squamous cell carcinoma (scc) of the esophagus with pancreatic metastasis. a 59-year old woman was admitted with chief complaint of abdominal pain and mass. she was a known case of esophageal scc since 4 years before when she had undergone transthoracic esophagectom...

Previous molecular genetic studies of laryngeal squamous cell carcinoma (SCC)have shown certain chromosomal regions with recurring alterations. But studies of sequential molecular alterations and genetic progression model of laryngeal SCC have not been clearly defined. To identify the chromosomal alterations associated with the carcinogenesis of laryngeal SCC, we analyzed genomic DNA from micro...

Background: Tumor volume doubling time (VDT) has been shown to predict prognosis in various non-small cell lung carcinoma with scant evidence for squamous (SCC). The purpose of this study was investigate the prognostic value tumor VDT resected SCCs.

Sir, Squamous cell carcinoma (SCC) can occur anywhere on the skin and in mucous membranes with a squamous epithelium (1). Malignant tumours producing granulocyte colony-stimulating factor (G-CSF) have been reported in lung cancer, thyroid carcinoma, bladder carcinoma and cutaneous angiosarcoma (2). We encountered a case of G-CSF-producing SCC, which was diagnosed by immunohistochemical staining...

HLP: hypertrophic lichen planus LP: lichen planus PEH: pseudoepitheliomatous hyperplasia SCC: squamous cell carcinoma INTRODUCTION Hypertrophic lichen planus (HLP) and squamous cell carcinoma (SCC) share many clinical and histopathologic characteristics, making them difficult to distinguish. HLP may undergo malignant transformation, leading to the development of SCC within HLP. We present a cas...

background and aims. several diagnostic methods are being employed to detect benign and malignant lesions, one of which is silver nitrate staining for organizer regions. the number of nucleolar organizing regions (nors) can be used to show the degree of cell activity or metabolism in pathologic lesions. this study was designed to evaluate nors as determinants of precancerous and squamous cell c...

OBJECTIVE To study the cytomorphological features of squamous cell carcinoma (SCC) in serous effusions. METHODS Conventional smears from 23 SCC were reviewed for the following features: cellularity, single cells, cell clusters, long cords, squamous pearls, cell-in-cell, 'windows', polygonal cells, anucleated cells, tadpole cells, fibre cells, third-type cells, refractile cytoplasmic ring, two...
