Tubuloreticular inclusions in systemic lupus pneumonitis. Report of a case and review of the literature

Tubuloreticular inclusions have been described with sufficient frequently in certain tissues of patients with systemic lupus erythematosus (SLE) to make the finding of such inclusions helpful in making a diagnosis of this disorder. The finding of such inclusions in lung biopsy specimens, however, has been distinctly rare. We report herein the ultrastructural findings in the case of a young woman with active systemic LE showing tubuloreticular inclusions within lung and kidney biopsy specimens.
