Spleen is an uncommon site of tumor metastases, usually as a part of multivisceral metastatic disease. Breast, lung, ovarian, colorectal, and gastric carcinomas and skin melanoma are the most common primary sources. Isolated metastasis to the spleen is extremely rare especially from lung with only 8 cases reported to date in literature. Splenic metastasis is often asymptomatic and radiologically mistaken for primary splenic lesions. Hence clinical suspicion and pathological confirmation is essential with careful and extended follow up for prompt therapeutic intervention. Here we report a rare case that presented with abdominal symptoms and massive splenomegaly and revealed isolated splenic metastasis from moderately differentiated adenocarcinoma in left lung.
