title: [Undifferentiated carcinoma(endocrine cell carcinoma) of the colon].
abstract: Recently, several cases of undifferentiated carcinoma and endocrine cell carcinoma are reported in the Japanese literature. In some reports, it is seemed to be confused in differentiating the diagnosis of these carcinomas, and considered that these carcinomas are in the same entity. When undifferentiated carcinoma of the large intestine is indicated, aggressive exploration such as immunohistochemical staining entertaining a possible existence of endocrine cell carcinoma is essential. Both undifferentiated carcinoma and endocrine cell carcinoma have the least favorable prognosis and effective multimodal therapy, including operation and chemoradiotherapy should be established.
