Sarcoidosis and giant splenomegaly.
Splenomegaly is often a manifestation of sarcoidosis, but giant splenomegaly is rare. Only 25 cases of sarcoidosis presenting as massive splenomegaly have been reported. Splenectomy was performed before the diagnosis of sarcoidosis was made in more than half of these patients. Serious complications of giant splenomegaly including rupture, severe thrombocytopenia and hemolytic anemia were not consistently present preoperatively. A case of disseminated sarcoidosis presenting with giant splenomegaly and normal chest roentgenograms is described. Prednisone therapy improved the patient's pulmonary function testing while constitutional symptoms, splenomegaly and elevated angiotensin-converting enzyme levels completely resolved. Sarcoidosis should be considered in the differential diagnosis of massive splenomegaly. A trial of steroids is warranted as initial treatment, and in selected cases may prevent unnecessary splenectomy, thereby precluding a compromise in host defenses against encapsulated bacteria.
