Hemoperitoneum from Spontaneous Rupture of a Liver Cell Adenoma in a Male with Hyperthyroidism

Spontaneous liver rupture is uncommon, is difficult to diagnose, and carries a high mortality. Liver cell adenoma is a rare benign liver tumor with increasing incidence in women on oral contraceptive pills, and they have been reported to rupture spontaneously. In men such a phenomenon is an extreme rarity. In animal experiments thyroid hormone is proven to play a role in the growth of liver cell-derived neoplasms as they do in normal hepatocyte proliferation. An association of liver cell adenoma and hyperthyroidism in humans has not been previously reported. We present the successful management of an unusual case of spontaneous hemoperitoneum from rupture of a liver cell adenoma in a young man with hyperthyroidism.
