Primary Neuroectodermal Tumor: A Case Report And Review Of The Literature

The primary neuroectodermal tumor (PNET) arising in the colon is extremely rare. We reported a case of 26-year-old male colonic PNET patient whose initial symptoms were just diarrhea and paroxysmal pain. This PNET patient's journey from onset to death only lasted one and a half months, losing opportunities of surgery, radiotherapy and chemotherapy. We wish to draw the attention of our colleagues to the occurrence of PNET of colorectal origin. At the same time, long-term observation or medical follow-ups may be extremely important for a patient whose cause is not fully understood.
