Peliosis is a condition characterized by presence of multiple blood filled cysts within the parenchyma of a solid organ. Peliosis affecting spleen is usually seen in association with peliosis of liver. Isolated splenic peliosis “peliosis lienis” is a unique phenomenon. At Government Medical College, Thiruvananthapuram, Kerala, India we had one such case. Dead body of a 27 year old male was brought for medico legal autopsy with history of being found dead in the morning. He had a history of mild abdominal pain on the previous day. Autopsy revealed splenic peliosis with rupture of spleen and haemoperitoneum.
