• Splenomegaly

  Significant symptomatic splenomegaly requiring splenectomy is very unusual for this disorder; therefore there is a lack of descriptions of the morphologic features of the spleen in the literature. [ncbi.nlm.nih.gov]

• Massive Splenomegaly

  We present here one of the first detailed descriptions of the morphologic and immunohistochemical features of the spleen from a young female with PPBL who developed massive splenomegaly during 6-year follow up. [ncbi.nlm.nih.gov]

  Massive splenomegaly is rare among these patients. Our PPBL patient reported here manifested slowly progressive splenomegaly during six years of follow-up. [diagnosticpathology.biomedcentral.com]
