[Primary hepatic carcinoid]

Area of Science:

• Oncology
• Gastroenterology
• Pathology

Background:

• Primary hepatic carcinoid (PHC) is an exceptionally rare malignancy, with fewer than 60 reported cases globally.
• Diagnosis is challenging due to its sporadic nature and potential for asymptomatic progression, often mimicking other hepatic lesions.

Observation:

• A 72-year-old patient presented with minimal symptoms, later diagnosed with generalized PHC after extensive workup including OctreoScan and histology.
• The case illustrates the difficulty in diagnosing PHC, requiring exclusion of other primary tumor sites.

Findings:

• Histological confirmation post-mortem validated the clinical diagnosis of generalized PHC.
• The patient received palliative therapy with somatostatin analogues.

Implications:

• This case underscores the importance of considering PHC in the differential diagnosis of hepatic lesions, especially with atypical presentations.
• Advanced imaging and thorough exclusion of metastatic disease are crucial for accurate PHC diagnosis.
