Sarcoidosis presenting as isolated massive splenomegaly: A case report

Sarcoidosis is a systemic disease of unknown cause, marked by the presence of noncaseating granulomas in affected organs. It most frequently impacts the pulmonary interstitium, though it can also affect nearly any other organ system. This involvement can occur with or without lung involvement, but isolated extrapulmonary cases are observed in only about 10% of instances. Furthermore, isolated splenomegaly is an exceptionally rare event and an uncommon presentation of sarcoidosis, posing a significant clinical challenge due to the wide differential diagnosis. Potential differential diagnoses include hematologic cancers, primary or metastatic splenic tumors, infiltrative diseases, inflammatory conditions, and infections. We present a noteworthy case of a 28-year-old with isolated splenic sarcoidosis.
