Neuroendocrine cell carcinoma of ascending colon

Concurrent Large Cell Neuroendocrine Carcinoma and Adenocarcinoma of the Ascending Colon: A Case Report

Large cell neuroendocrine carcinomas of the colon are rare and represent only a small percentage of all colonic endocrine tumors. Here, we report a case of a colonic large cell neuroendocrine carcinomas concurrent with a colonic adenocarcinoma. A 70-year-old man presented with acute abdominal pain. A spiral computed tomography scan of the abdomen revealed eccentric wall thickening on the ascend...

Squamous cell carcinoma of the ascending colon: two cases

Squamous cell carcinoma (SCC) of the colon without known primary source is a rare finding that needs aggressive management. We report two cases of SCC of the colon without any clear extra-colonic source despite extensive workup. In our experience, the clinical course and prognosis are largely dependent on the presence of metastatic disease at diagnosis. The main treatment is surgery, with chemo...

Synchronous carcinoma of the ascending colon and caecum.

The caecum and the ascending colon are the colon segments most frequently affected by tumoral synchronism. Synchronous colorectal carcinoma etiopathogenesis is complex and most likely by malignancy of preexisting adenomas (adenoma-adenocarcinoma sequence). The following tumoral synchronism clinical case's particularity is represented by the simultaneous diagnosis of a flat-type adenocarcinoma o...

Pulmonary Large-Cell Neuroendocrine Carcinoma

Lung neuroendocrine tumors are a heterogeneous sub-type of pulmonary cancers representing approximately 20% of all lung cancers, including small-cell lung cancer (SCLC) and large-cell neuroendocrine carcinoma (LCNEC). The frequency appears to be approximately 3% for LCNEC. Diagnosis of LCNEC requires attention to neuroendocrine features by light microscopy and confirmation by immunohistochemica...
