Huge Littoral Cell Angioma of the Spleen: A Case Report.

Littoral cell angioma (LCA), a rare vascular neoplasm that occurs in the spleen, is difficult to definitively diagnose preoperatively because histological examination is the only accurate means of diagnosing this condition. Thus, the preoperative diagnosis is often incorrect. Splenectomy is the appropriate treatment and can be performed laparoscopically or by open surgery depending on the size of the tumor. Here we present a case of a 38-year-old man who presented with a history of slight non-specific abdominal distension for 2 months. An abdominal CT scan showed a huge spleen measuring 35×18 cm and containing multiple lesions, the largest being 11.3×9.2 cm. The patient underwent open splenectomy and recovered well. Histological examination showed LCA of the spleen. To our knowledge, this is the largest reported LCA thus far and may advance our understanding of this condition.
