D73.1

Clinical Causes: Chronic liver diseases such as cirrhosis or hepatocellular carcinoma Hematological disorders including leukemia, lymphoma, or myeloproliferative diseases Infections like malaria and mononucleosis Autoimmune conditions such as systemic lupus erythematosus Spleen enlargement due to trauma or congestion Other underlying conditions leading to spleen overactivity

Key Symptoms: Splenomegaly (enlarged spleen detectable on physical exam or imaging) Anemia, resulting in fatigue, weakness, and pallor Thrombocytopenia, which can cause easy bruising, bleeding, or petechiae Leukopenia, increasing susceptibility to infections Fullness or discomfort in the upper left abdomen Unintentional weight loss in some cases Fever associated with underlying infections or systemic conditions

Diagnosis Path: Physical examination revealing enlarged spleen Blood tests to evaluate blood cell counts and identify cytopenias Imaging studies like ultrasound, CT scan, or MRI to confirm spleen size and structure Bone marrow examination if hematologic origin is suspected Additional tests to determine underlying causes, such as infectious disease screening or autoimmune panels

Treatment Protocols: Observation and regular monitoring if blood cell counts are only mildly affected and no significant symptoms are present Treating underlying conditions, such as infections or autoimmune disorders, to reduce spleen activity Medications to manage symptoms or underlying causes, including immunosuppressants or anti-inflammatory drugs Splenectomy (surgical removal of the spleen) in severe cases unresponsive to other treatments or when complications arise Supportive care, such as blood transfusions or growth factors, to correct severe anemia or cytopenias
