We report 2 cases of splenic vascular
tumors that were successfully treated by hand-assisted laparoscopic
splenectomy. Two patients, a 41-year-old woman and a 33-year-old man, were admitted to our department for investigation of a splenic
tumor. After ultrasonography, computed tomography, and magnetic resonance imaging, we suspected that the masses were
hemangioma or
inflammatory pseudotumor in the spleen. However, we preoperatively could not rule out the possibility of a
malignant neoplasm because they each had previously undergone surgical treatment, one for
cervical cancer of the uterus and the other for testicular
seminoma. Hand-assisted laparoscopic
splenectomy was safely performed for the diagnosis and treatment of the splenic
tumors. A histologic diagnosis was venous
hemangioma and
littoral cell angioma, respectively. Hand-assisted laparoscopic
splenectomy may be a good indication for splenic vascular
tumors that are difficult to diagnose preoperatively whether they are malignant or benign.
