Abstract

We herein report a rare case of solitary splenic metastasis of a pulmonary carcinoid, for which hand‑assisted laparoscopic splenectomy was performed. A 73‑year‑old man was admitted to the Inoue Hospital (Fukuyama, Japan) in March 2015 with an abnormal shadow of the spleen. The patient had a history of right upper lobectomy with lymph node dissection for a pulmonary typical carcinoid (pT1N0M0 stage IA) 7 years earlier. Plain abdominal computed tomography (CT) revealed a low‑density area in the spleen. Enhanced abdominal CT revealed a mass in the spleen measuring 3x3 cm. Blood tests and tumor marker analysis revealed no abnormalities. Abdominal magnetic resonance imaging revealed a mass that was low‑intensity on T1‑ and high‑intensity on T2‑weighted images, and positron emission tomography revealed abnormal fluorodeoxyglucose accumulation in the mass. Hand‑assisted laparoscopic splenectomy was performed for diagnosis and treatment. The resected specimen included a reddish‑brown mass. On immunohistochemistry, the mass was positive for chromogranin A, synaptophysin and CD56, which was similar to the resected pulmonary carcinoid tumor; thus, splenic metastasis of pulmonary carcinoid was diagnosed. The postoperative course was uneventful and the patient is currently under observation and remains recurrence‑free, with no adjuvant chemotherapy.
