Malignant Mixed Müllerian Tumors (MMMT) also referred to as carcinosarcomas are very rare and extremely aggressive tumors of the uterine corpus accounting for less than 1% of all gynecologic malignancies, 2-5% of all uterine malignancies and more than 15% of all uterine cancer associated deaths [1]. They occur almost exclusively in post-menopausal women, but have been reported in premenopausal women as well, including young girls [2]. Carcinosarcomas have poor prognostic outcome, regardless of stage at diagnosis. The five-year survival rate ranges between 5% and 40% for patients with tumors of all stages [2-5] and does not improve significantly even with the introduction of increasingly aggressive adjuvant therapies.

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% [1], and most often is encountered in adults between the ages of 30 and 50 [2]. 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 [3].
