[Rectal endocrine intermediate-cell carcinoma].
An 82-year-old patient complained of diarrhea due to a rectal endocrine intermediate-cell carcinoma. Histology displayed a neuron-specific enolase and CD56 immunoreactive tumor. Hepatic metastases developed rapidly and the tumor was briefly reactive to radiotherapy and chemotherapy. These tumors are rare and have a poor prognosis. We focus on the recent classification of gastrointestinal endocrine tumors.
