Abstract
The authors describe multiple telangiectatic or inflammatory adenomas in a 53-year-old woman with steatohepatitis who presented with acute right upper quadrant abdominal pain. Magnetic resonance imaging revealed 6 lesions consistent with multiple hepatic adenomas, 2 of which showed hemorrhage. She underwent right lobectomy and nonanatomical segment 2 liver resections and seven nodules ranging in size from 1.0 to 5.0 cm were identified. All nodules contained portal-like structures and ductular reaction, features seen in focal nodular hyperplasia, as well as significant inflammation, telangiectatic sinusoids and immunoreactivity for serum amyloid A, placing them according to a recently described classification systems as telangiectatic or inflammatory adenomas. The diffuse positivity of the serum amyloid A staining results in this case suggests an important diagnostic role of this stain in smaller tissue samples, such as in core biopsy specimens.
