Abstract

Fine needle aspiration cytology is currently of great interest in the diagnosis of tumors and also in monitoring the course of organ transplants (1-4). Specimens may be procured with little associated trauma to the tissue or discomfort to the patient (5,6). In the case of kidney transplantation, daily biopsies may be carried out to determine the possible onset of rejection episodes (4). Cytological assessment of the types and extent of any mononuclear cell infiltrate are critical in determining the possible immunosuppressive protocols that are used in kidney grafting (6). T.E.M. studies of fine needle aspirates from kidney specimens are very limited and little attention has been paid in such cases to glomeruli present in the samples. Glomerular changes although not critical in renal transplant rejection are of great interest in diagnosis of many renal diseases.
