Splenic hemangioma is a vascular malformation which is one of the most common benign neoplasms of the spleen. They may represent small, incidental lesions that can produce significant splenomegaly and predispose to splenic rupture. These tumors are rare and resemble their counterparts in other organs. The vascular spaces are usually irregular and cavernous, containing abundant red blood cells.
Differential diagnoses include benign or malignant neoplasms, metastases, lymphoma, splenic abscess or cystic lesions. The incidence of autopsy examination of their diagnosis ranges from 0.03 to 14% , and most often is encountered in adults between the ages of 30 and 50 . Most are small lesions, usually clinically silent, diagnosed accidentally. Sometimes, however, they may be symptomatic, manifested by splenomegaly, abdominal pain, bowel disorders, anemia and thrombocytopenia, Kasabach-Merritt syndrome (anemia, thrombocytopenia and coagulopathy) and in rare cases by spontaneous rupture of the spleen .
