title: Primary liver leiomyoma: a review of this unusual tumour.
abstract: Primary liver leiomyoma (PLL) should be considered in the differential diagnosis of liver lesions. A literature review has been completed and two cases are reported. The first is a 45-year-old white woman complaining of vague abdominal pain. She was initially evaluated with abdominal ultrasonography (US) that revealed a heterogeneous liver mass measuring 18 cm in greatest diameter. The tumour demonstrated hypointensity on T1-weighted and hyperintensity on T2-weighted magnetic resonance imaging. The second case is a 45-year-old Asian male who had undergone kidney transplantation 16 years ago for IgA glomerulonephritis and who developed mild, self-limiting epigastric pain. US showed a 4.3-cm-diameter lesion that was predominantly hypoechoic and was either compressing or arising from segment 2 of the liver. Computed tomography showed a well-circumscribed 4-cm-diameter mass that appeared to be arising from segments 2/3 of the liver and was adjacent to the anterior gastric wall. He underwent an uneventful laparoscopic left lateral sectionectomy and discharged on post-operative day 3. Pathological examination of the resection specimen confirmed the lesion as a PLL in each case. Herein, we report two cases of PLL and review the literature regarding this uncommon disorder.
