Abstract
Ribosome-lamella complexes (RLCs) are mainly observed in a variety of hematological disorders and occasionally in solid neoplasms and in nonneoplastic diseases. These intracytoplasmic organelles are held to arise from rough endoplasmic reticulum, but, in agreement with more recent literature data, their function is still unclear. Ultrastructural analysis of glomeruli from a patient with focal segmental glomerulosclerosis secondary to metabolic syndrome disclosed significant foot process loss and abundant cytoskeletal proteins in major podocyte processes; two of the latter also displayed RLCs. This is the second report of RLCs in human renal glomerulus. Their close association with cytoskeletal proteins and lysosomes suggests a relationship with abnormal protein biosynthesis.
