My mother died of this in November of 1991. The diagnosis was given in August of 1991. It was very difficult to diagnose. I am trying to learn about it, however it is hard to find much information. Thank you for the content.

As a french pathologist with interest in lung and thoracic pathology, i couldn’t expect better!
Is thymus pathology is included?
Many thanks

Thanks for the teaching! I'm an intern (prelim for radiology), and late one night I admitted a patient with bizarre diffuse opacities on CXR (CT the next day ended up showing innumerable pulmonary nodules). This was during the height of COVID-19, so I passed the patient off to the day-team assuming COVID PCR would be positive. Later had a bronch when she became sicker - path showed EBV+ LYG. Interestingly, when I looked back at a previous path report for a cutaneous nodule, it also was suspicious for LYG! The patient had a history of rheumatoid arthritis with chronic use of methotrexate.

Thanks! Nice case. So, when are we going to stop calling it Lymphomatoid *Granulomatosis* ? Perhaps with this case ? :-)
