Gastroenterology
Oncology
Pathology

Background:

Gastrointestinal neuroendocrine neoplasms (GI-NENs) are rare tumors.
Rectal neuroendocrine neoplasms (NENs) represent the second most common type in China.
Non-specific symptoms like bloody stools can indicate rectal NENs.

Observation:

A 68-year-old male presented with bloody stools, a common symptom of rectal NENs.
The patient underwent surgical intervention for the suspected rectal NEN.
Postoperative pathology confirmed the diagnosis of a well-differentiated neuroendocrine carcinoma.

Findings:

The case details a rare instance of rectal NEN.
Surgical treatment was effective in this patient.
Postoperative analysis revealed a well-differentiated neuroendocrine carcinoma.

Implications:

This case contributes to understanding the clinical presentation and management of rectal NENs.
Highlights the importance of surgical intervention for rectal NENs.
Emphasizes the need for accurate postoperative pathological diagnosis in rare GI-NENs.
