Sarcoidosis is a systemic granulomatous disease of unknown etiology characterized by presence of noncaseating granulomas in the involved organs. The pulmonary interstitium is most commonly affected but extrapulmonary involvement can occur in almost any other organ system. Such an involvement can occur with or without the presence of pulmonary involvement, but isolated extrapulmonary involvement has been noted only in around 10% of cases. Isolated splenomegaly is very rare and an uncommon presentation of sarcoidosis. It is clinically challenging because of the extensive differential diagnosis. Among the many considerations are hematologic malignancies, primary splenic or metastatic tumors, infiltrative disorders, inflammatory disorders, and infections. We hereby discuss an interesting case of a 40-year-old female with isolated splenic sarcoidosis.
