RESUMO
Splenic metastasis from solid cancer is a rare clinical event. Especially splenic metastasis from the lung is very rare. Most spleen metastases are found at autopsy and are part of a widely spread disease. Solitary splenic metastasis in the abscence of other metastases is extremely rare. The authors report the case of a 54-year-old man in whom the only discover distant metastasis from lung cancer was a splenic mass. The splenic lesion was detected after the resection of the primary lung lesion. The time from diagnosis to the development of splenic metastasis was 25 months. The rarity of a solitary spleen metastasis from lung cancer and the treatment modalities are discussed. When solitary spleen metastasis is suspected in a clinical setting, aggressive treatment is indicated, a splenectomy followed by combined modality treatment to prevent the spread and aggravation of the disease.
