Topic Outline. Monomorphic PTLD Monomorphic PTLD are monoclonal lymphoid proliferations that meet the criteria for one of the B cell or TNK cell lymphomas recognized in immunocompetent patients. These conditions lie along a continuum of disease and are categorized by the 2008 World Health Organization classification system as PTLD [ 1. Pitfalls and differential diagnosis. Cases showing partial involvement of a lymph node may be mistaken for reactive paracortical hyperplasia.

It is one of the most common posttransplant malignancies. Jul 01, 2001 The diagnosis of PTLD historically has been associated with a mortality rate of 5080 in patients who have a monoclonal form of the disorder [1, 3. Recently described aggressive approaches to diagnosis and treatment of PTLD have the potential to improve outcome, however, as discussed below. The diagnosis of PTLD can be devastating and it is imperative to complete a thorough diagnostic workup prior to causing undue emotional distress. Conclusions: Constitutional symptoms, extranodal masses, and transplant dysfunction may be suggestive of PostTransplant Lymphoproliferative Disorder. A diagnosis of a posttransplant lymphoproliferative disease is based upon identification of characteristic symptoms, a detailed patient history, a thorough clinical evaluation and a variety of specialized tests, including a complete blood count (CBC), chemical panel, specialized imaging (xray) techniques, an evaluation for the EpsteinBarr virus, and a tissue biopsy.
