I highly recommend trying Open Evidence AI. It deals solely with medical questions and is available only to physicians. It is affiliated with the New England Journal of Medicine and Elsevier Publishing. I have been impressed with its performance. In July 2023, OpenEvidence's AI achieved a groundbreaking milestone by scoring over 90% on the United States Medical Licensing Examination (USMLE), marking the first time an AI system surpassed this threshold.

These two collages display a variety of seeds that pathologists may encounter when examining tissues microscopically. Some of the seeds have a very distinctive appearance permitting their recognition whereas others resemble other seeds, and their origin may be difficult to recognize. They are all in the Atlas of Medical Foreign Bodies (flickr.com/phoytos/foreig…)

The biopsy shows non-necrotizing granulomas. Non-necrotizing granulomas suggest a non-infectious etiology such as sarcoidosis, but mycobacterial infection can also sometimes present with non-necrotizing granulomas. Was AFB stain and/or culture done? The likely diagnosis in cases such as this one requires correlation of clinical, radiologic, and laboratory findings (serum ACE, culture) with the biopsy findings and should be made by the clinician rather than the pathologist.
