Peliosis of spleen is usually associated with peliosis of liver. Oval to round markedly dilated blood filled cystic spaces predominantly in parafollicular area is the characteristic feature of peliosis to differentiate it from congested sinuses. Exposure to viruses chemicals, contraceptive steroids or chronic debilitating disorders including malignancies are the various possible etiological factors. Though peliosis may remain asymptomatic, fatal intraperitoneal haemorrhage may occur due to its rupture. We report a case of peliosis of spleen presenting as splenic rupture with haemoperitoneum.
