Histological type of esophageal cancer

The vast majority of esophageal cancer occurred in esophageal mucosa, a small number of sources in the leaf tissue sarcoma embryo. Esophageal cancer in more than 95% of squamous cell carcinoma, a small number of ectopic origin of the esophageal glands or gastric adenocarcinoma, squamous cell and adenocarcinoma occasionally combined with a cancer in the […]

Advanced gastric pathological classification of section

Carcinoma infiltrating into the submucosa are less advanced gastric cancer , or known in advanced gastric cancer. The deeper the cancer, the worse the prognosis, invasion to serosa than 5-year survival rate; invasion to the muscular layer of the significantly reduced.Advanced gastric pathological type of segment, the current widely used international classification of Borrmann's gross.

Central lung cancer (centre type) that the hilar type (hilar type) of lung […]

Abnormal squamous cell lung cancer

Abnormal squamous cell carcinoma of the variation of the morphological structure, forming a variant of squamous cell carcinoma (variants). Include the following types: papillary type (papillary variant); small cell type (small cell variant); basal cell-like types (basaloid variant); clear cell type (clear cell variant). These variant of squamous cell carcinoma squamous cell carcinoma often in […]

Squamous cell carcinoma of the lung peripheral

Peripheral pulmonary squamous cell carcinoma in peripheral lung squamous cell carcinoma, squamous cell carcinoma as target type (peripheral squamous cellcarcinoma), referred to as peripheral squamous cell carcinoma. Peripheral squamous cell lung cancer accounts for 7% of the total number of 14%. (1) histological features and clinical: peripheral pulmonary squamous cell carcinoma of the age, sex, […]

Overview of small cell lung cancer

General overview of small cell lung cancer, small cell lung cancer is the lung (bronchial) epithelium highly malignant, undifferentiated, with neuroendocrine differentiation of cancer. Cancer is small; cytoplasm less ill-defined cells; was slightly granular chromatin, no nucleolus or nucleoli was not significant; fission common. Small cell lung cancer is highly malignant cancer with neuroendocrine differentiation. […]

Characteristics of lung cancer Introduction

Lung cancer (adenocarcinoma) is the lung (bronchial) epithelial cancer. Adenoid differentiation of tumor cells or cancer cells secrete mucus. Tumor tissue can be presented alveolar (acinar), papillary (papillary), bronchioloalveolar-like (bro with hioloalveolar), solid structure with mucus formation (solid with mucin formation) or the various types of mixing. Adenocarcinoma of lung cancer histological types in common. […]

Variant of large cell carcinoma – large cell carcinoma with rhabdoid phenotype

Variant of large cell carcinoma – large cell carcinoma with rhabdoid phenotype: the type of cancer cells was eosinophilic intracytoplasmic inclusion bodies with large cell carcinoma, a rare case. the naked eye: the tumor border is unclear. Section gray-brown, often accompanied by focal hemorrhage and necrosis. microscope: cell nucleus large, vacuolization, prominent nucleoli. Part of […]

Variant of large cell carcinoma – clear cell carcinoma

Variant of large cell carcinoma – clear cell carcinoma (clear cell carcinoma): as an independent type of lung cell carcinoma is extremely rare. the naked eye: tumors are peripheral, tumor boundaries with the surrounding lung tissue is unclear, the size of one. Grayish yellow cut surface, may be associated with hemorrhage and necrosis. variant of […]
