Which inclusion is commonly seen in patients after splenectomy?

The key idea is that the spleen normally filters out abnormal nuclear remnants from red blood cells. When the spleen is removed, these remnants stay in circulation, so certain inclusions become visible on a peripheral smear. Howell-Jolly bodies are small, round basophilic nuclear remnants inside red blood cells. Their presence signals lack of splenic filtration, as these fragments would normally be cleared by a functioning spleen. After splenectomy, Howell-Jolly bodies commonly appear because the spleen’s filtering function is gone, allowing these nuclear remnants to persist in circulating erythrocytes. For context, Heinz bodies are precipitated hemoglobin seen with oxidative stress (such as G6PD deficiency) and are not specifically tied to splenectomy. Target cells are red cells with a membrane abnormality pattern seen in liver disease or certain anemias. Pappenheimer bodies are iron-containing inclusions that can appear in sideroblastic anemia and other conditions; they are not the classic finding linked to splenectomy.
