Partial splenectomy for littoral cell angioma.

Littoral cell angioma is a rare primary splenic tumor that is difficult to differentiate preoperatively from other benign and malignant splenic lesions and may have immunogenic origins. Preoperative ultrasound and computed tomographic scan showed that our patient's lesion was solitary and localized. Total splenectomy is usually required because littoral cell angioma is generally large and/or diffuse. However, a partial splenectomy was able to be performed, making this the first reported partial splenectomy for littoral cell angioma.
