We report a very rare case of splenic hamartoma. A 35-year-old woman with a 38°C fever, myalgia, and arthralgia since September 2007 was seen in October 2007, at which time she underwent computed tomography (CT) to clarify slight liver-function abnormalities. She was found to have a 3 cm splenic tumor, but detailed systemic postadmission examinations indicated no malignancy of other organs. We conducted laparoscopic splenectomy in November for a suspected primary splenic tumor. The operation took 80 minutes and blood loss was 20 mL. To minimize the spleen removal incision, we placed the spleen in an Endo CatchIITM, where it was divided into three segments prior to extraction. The excised specimen showed relatively well-demarcated, uncovered 3×2.5 cm nodular lesions that were found in histopathological examination to be proliferated splenic cord capillaries in the red pulp. Immunostaining was positive for CD34 and negative for CD8 and factor VIII. Morphology and immunophenotypic studies yielded a diagnosis of splenic cord capillary hemangioma classified as splenic hamartoma.
