Hi all! So we all know about constrictive bronchiolitis, but can it happen in large airways? Below is post-SBRT obliterative bronchitis of LLL with secondary necrotizing granulomatous consolidation - awaiting stains but betting on NTM. A sort of (non) middle lobe syndrome!

Do you recognize these seed-derived storage cells (images courtesy of @oreoimc)? See the latest publication on these cells and the lesions they produce co-authored by me, @Histopatolomon. and @navale_pooja at rdcu.be/cz4ZC. A Twitter inspired collaboration.

Bag of worms. Hydrophilic polymer embolisation with secondary thrombosis. This is a thrombectomy specimen from the right femoral artery in a patient undergoing peripheral vascular surgery. The guidewires are coated in this material that can occasionally embolize. Yikes!

Thanks to all who engaged! Although uncommon, chronic LCH can lead to severe secondary pulmonary HTN which is what we see here. A spectrum of arterial lesions, including plexiform, dilatation, and medial hypertrophy. Wishing the patient a new lease on life with new lungs!

@yro854 Indeed classic LCH, advanced. Must say that image in isolation could indeed be a recanalized thrombus but overall it just looks like a constellation of arterial lesions within the spectrum of non-thombotic HTN, secondary to underlying lung disease. I'll share more images.

@thoracicpath Langerhans cell histiocytosis and a recanalized artery, probably a late stage of pulmonary thromboembolism. Awaiting revelation of the relationship, if any, between both lesions.
