| Adenocarcinoma of colon (WHO code: 8140/3) |
Colon Adenocarcinoma |
C4349 |
NCI Thesaurus |
An adenocarcinoma arising from the colon. It is more frequently seen in populations with a Western type diet and in patients with a history of chronic inflammatory bowel disease. Signs and symptoms include intestinal bleeding, anemia, and change in bowel habits. According to the degree of cellular differentiation, colonic adenocarcinomas are divided into well differentiated, moderately, and poorly differentiated. Morphologic variants include the mucinous adenocarcinoma and signet-ring adenocarcinoma. Lymphatic or hematogenous spread can occur early in the process and lead to systemic disease. |
| Carcinoma of colon, NOS (WHO code: 8010/3) |
Colon Carcinoma |
C4910 |
NCI Thesaurus |
A malignant tumor usually arising from the epithelium lining the large intestinal mucosa. Colon carcinoma is one of the most common malignancies in both males and females, and is especially common in North America and Europe. Grossly, most colon carcinomas are polypoid or ulcerating lesions. Microscopically, adenocarcinoma is the most frequently seen morphologic subtype. Prognosis depends on the stage of the disease (depth of invasion, metastasis to regional/distal lymph nodes or other anatomic sites). -- 2004 |
| Carcinoma of colon, adenosquamous (Who code: 8560/3) |
Colon Adenosquamous Carcinoma |
C5491 |
NCI Thesaurus |
An unusual colon carcinoma characterized by the presence of glandular and squamous carcinomatous components. The two carcinomatous components may be admixed within the tumor, or the two may appear separately in different areas. |
| Carcinoma of colon, medullary (WHO code: 8510/3) |
Colon Medullary Carcinoma |
C60641 |
NCI Thesaurus |
A rare, invasive colon adenocarcinoma characterized by the presence of sheets of malignant epithelial cells with vesicular nuclei, prominent nucleoli, and abundant eosinophilic cytoplasm. It usually has a favorable prognosis. |
| Carcinoma of colon, mucinous (colloid type)(greater than 50% mucinous carcinoma)(WHO code: 8430/3) |
Colon Mucinous Adenocarcinoma |
C7966 |
NCI Thesaurus |
An invasive adenocarcinoma of the colon characterized by the presence of pools of extracellular mucin. Malignant glandular epithelial cells are present in the mucin collections. Mucin constitutes more than 50% of the lesion. |
| Carcinoma of colon, signet ring cell (greater than 50% signet ring cell)(WHO code: 8490/3) |
Colorectal Signet Ring Cell Carcinoma |
C43586 |
NCI Thesaurus |
An invasive colorectal adenocarcinoma characterized by the presence of malignant glandular epithelial cells with prominent intracytoplasmic mucin resulting in the displacement of the nuclei. The malignant glandular cells with intracytoplasmic mucin constitute more than 50% of the malignant cellular infiltrate. |
| Carcinoma of colon, small cell (WHO code: 8041/3) |
Colon Small Cell Neuroendocrine Carcinoma |
C6761 |
NCI Thesaurus |
An aggressive, high-grade, and poorly differentiated carcinoma with neuroendocrine differentiation that arises from the colon. It is characterized by the presence of malignant small cells. |
| Carcinoma of colon, squamous cell (epidermoid)(WHO code 8070/3) |
Colon Squamous Cell Carcinoma |
C5490 |
NCI Thesaurus |
A very rare colon carcinoma characterized by the presence of a malignant squamous cell infiltrate. |
| Carcinoma of colon, undifferentiated (WHO code: 8020/3) |
Colon Undifferentiated Carcinoma |
C7100 |
NCI Thesaurus |
An invasive malignant epithelial tumor that arises from the colon. There is no morphologic, immunophenotypic, or molecular biological evidence of glandular or squamous differentiation. |
