Enlarged spleen syndrome

O G Ajao

    Journal of the National Medical Association

    Summary
    This summary is machine-generated.

    Enlarged spleens, often misdiagnosed as tropical splenomegaly, may actually be splenic abscesses or lymphosarcoma. Splenectomy is recommended for undiagnosed enlarged spleens to ensure accurate diagnosis and prevent complications.

    Area of Science:

    • Pathology
    • Hematology
    • Tropical Medicine

    Background:

    • Enlarged spleens of unclear origin are often termed "tropical splenomegaly" or "cryptogenetic splenomegaly," frequently attributed to malarial infestations.
    • Sickle cell disease can lead to splenic infarction, abscess, or a non-functional spleen.

    Purpose of the Study:

    • To investigate the histopathological findings of enlarged spleens previously diagnosed as tropical splenomegaly.
    • To evaluate the potential benefits of splenectomy in managing enlarged spleens of uncertain etiology and in sickle cell disease.

    Main Methods:

    • Histopathological examination of spleens removed surgically from patients with enlarged spleens.
    • Review of clinical presentations and outcomes in cases of sickle cell disease with splenic involvement.

    Main Results:

    • Histopathology revealed that most cases initially diagnosed as tropical splenomegaly were actually splenic abscesses or lymphosarcoma.
    • Some cases did meet the criteria for tropical splenomegaly, but this was less common than other pathologies.

    Conclusions:

    • Splenectomy is crucial for accurate diagnosis of enlarged spleens unresponsive to antimalarial therapy, preventing rupture, and guiding management.
    • Elective splenectomy may be a beneficial intervention in sickle cell disease to prevent splenic complications like abscess or fibrosis.
