Liver Subcapsular Hematoma: A Rare Cause of Sudden Unexpected Death.

The spontaneous subcapsular hematoma of the liver is very rare. There are only a few reported cases in the literature.Most reported cases of liver hematoma often occur during pregnancy as part of the hemolysis, elevated liver enzymes, and low platelet count syndrome. The other causes may be due to amylosis, rupture of hepatocellular carcinoma, adenoma, focal nodular hyperplasia, hemorrhagic cyst, or hemopathy. Idiopathic spontaneous subscapular hematoma is a rare and often fatal condition.We report a case of a 43-year-old woman having Steinert disease who died because of a fatal spontaneous liver hemorrhage occurring without any traumatism. We did not find any apparent cause that could explain this hemorrhage even after a histological study of the liver.

Sudden Death and Primary Leptomeningeal Melanocytosis: A Case Report With an Autopsy Diagnosis.

Meningeal melanocytoma is a rare benign pigmented tumor. It develops from melanocytes normally present in the meninges of the posterior fossa and medulla. It is an extra-axial tumor that manifests because of compression of adjacent structures. Although classified as a benign tumor, it can cause sudden death by several mechanisms. We report a rare case of meningeal melanocytoma and discuss the mechanism of death. A 21-year-old man with a previous history of recurrent lipothymia was admitted to the emergency department because of generalized seizures. Death occurred despite resuscitation. A medico-legal autopsy was performed. External examination of the body showed nonspecific asphyxia signs without any violence evidence. Necropsy noticed a brain edema with a dark color of the meninges especially in the frontal part. Histological examination concluded to diffuse meningeal melanocytoma with cerebral edema.
