Posttransplant lymphoproliferative disorder (PTLD) is a serious and potentially fatal complication after solid organ and haemopoietic stem cell transplantation. The frequency of PTLD varies with the type of organ transplant but overall it affects 2-10% of all solid organ transplant recipients. Most cases develop within 1 year after the transplant, although occasional cases present 5-10 years later. Posttransplant lymphoproliferative disorder is clinically and pathologically heterogeneous - the majority are of the non-Hodgkin's lymphoma type, whereas Hodgkin's lymphoma arising after transplantation is rare. We have retrospectively reviewed patients with a histological diagnosis of PTLD after a solid organ transplant. We present the imaging features and a clinical review of this condition. Early diagnosis of PTLD may alter the management and outcome of the disease. The radiologist can play a vital role in establishing the diagnosis by imaging features supplemented with percutaneous biopsy and also in monitoring the disease response to treatment.
The authors present a case of a healthy 61-year-old woman who presented with a 4-year history of progressive right upper eyelid ptosis. Excisional biopsy revealed malignant oncocytoma, an exceedingly rare tumor of the lacrimal gland.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
