Extract

Although liver function tests could be abnormal in humans taking cocaine the histopathological basis for this disorder has not been well established. Light microscopic studies have shown the existence of peripheral, centrilobular or diffuse necrosis. The only electron microscopic investigation we could find reports hepatocyte alterations including dilated rough endoplasmic reticulum, hypertrophy of smooth endoplasmic reticulum, and existence of phagolysosomes. In this work we report the liver ultrastructural pathology in chronic cocaine users.

Liver biopsies were obtained in five male patients, 25-44 years old. These patients had consumed cocaine and other drugs (marihuana, alcohol, amphetamines, etc..) for 7-30 years. All of them had altered liver function tests. Tissue samples were processed with routine techniques for transmission electron microscopy and observed in a Hitachi H-500 electron microscope.

Abnormalities observed included those previously reported as swollen rough and smooth endoplasmic reticulum, presence of autophagic vacuoles and lipid deposition.
