Summary
Hepatocellular adenoma (HCA), a rare liver neoplasm, can present unusually. This case details an extracapsular HCA originating from the stomach wall, highlighting a rare diagnosis and presentation.
Area of Science:
- Hepatobiliary pathology
- Gastrointestinal oncology
- Surgical case reports
Background:
- Hepatocellular adenoma (HCA) is a benign liver neoplasm.
- Oral contraceptive pills (OCP) are the primary risk factor for HCA.
- HCAs typically present as intracapsular liver masses.
Observation:
- A middle-aged female presented with left shoulder pain and epigastric tenderness.
- Abdominal imaging revealed a hemorrhagic mass on the stomach's anterior wall.
- Exploratory laparotomy confirmed a free hemorrhagic mass originating from the stomach.
Findings:
- Histopathology confirmed the mass as an infarcted inflammatory hepatocellular adenoma.
- This represents an extremely rare extracapsular presentation of HCA.
- The patient underwent successful surgical resection without complications.
Implications:
- This case highlights the importance of considering rare diagnoses in atypical presentations.
- It expands the known clinical spectrum of hepatocellular adenoma.
- Further research into extracapsular HCA presentations may be warranted.
