Solitary giant splenic metastasis in a patient with metachronous gastric cancers.

Splenic metastases from solid tumors are uncommon. They may be observed in a context of multivisceral dissemination or as a solitary lesion. We report the case of an 80-year-old woman with a history of two metachronous gastric cancers treated with distal gastrectomy and resection of the gastric remnant within a period of 15 years, who presented with a huge splenic tumor mass three years after the second operation. Splenectomy was performed. The resection specimens showed a well-circumscribed solid lesion measuring 15 cm in the largest diameter. Histology revealed metastatic gastric cancer. The differential diagnosis and clinical significance of this rare condition is discussed.
