Area of Science:

  • Oncology
  • Pathology
  • Gastroenterology

Background:

  • Primary hepatic carcinoid tumors are exceedingly rare, often presenting diagnostic challenges.
  • Distinguishing primary liver carcinoids from metastatic neuroendocrine tumors is crucial for patient management.

Observation:

  • A 57-year-old woman presented with a primary hepatic carcinoid tumor without endocrine symptoms.
  • Microscopic examination revealed characteristic trabecular/insular structures with Grimelius positivity.
  • Immunohistochemistry confirmed tumor cells positive for chromogranin A and cytokeratin.

Findings:

  • The tumor exhibited partial mucin presence, stained by Periodic acid-Schiff (PAS) and alcian-blue.
  • Extensive investigations ruled out other primary tumor origins.

  • The case underscores the importance of thorough diagnostic workup for hepatic carcinoids.

    • Implications:

    • Accurate diagnosis of primary hepatic carcinoid tumors is vital for appropriate treatment strategies.
    • This case contributes to understanding the clinical and pathological spectrum of rare liver neoplasms.
    • Further research into the pathogenesis and management of hepatic carcinoids is warranted.
