Incidental finding. Resection for met CA + CHF hx. Anything striking in alveolar septae imgs? Consider thoracic path training @MoffittNews "to contribute to the prevention and cure of cancer, focusing on groundbreaking research, expert patient care, and comprehensive education"

Diagnosing granulomatosis with polyangiitis on small biopsies (especially if not considering it) is very challenging. ANCA serologies, negative cultures, and pathologic suspicion were crucial in this case. Not everything is cancer at a cancer center. #lungpath #pathology #moffitt

Eosinophilic intranuclear inclusions (helioid bodies) are helpful features favoring UDH 2 possibilities exist about the helioid bodies: 1) They derive from modification of secretory granules sequestrated in an intranuclear inclusion 2) They develop by condensation of the contents

I also serve as Medical Director of Autopsy at @MoffittNews. Today, our outstanding residents @USFpathology @SaraNickii were finalizing cases when we encountered a very severe case of leukostasis in AML, involving essentially all vessels and causing ischemia in multiple organs

Non-neoplastic lung pathology is a major part of my work at @MoffittNews. Consider training in thoracic pathology with us! We are still accepting fellows for 2026-2027. Today’s case: metastatic pulmonary calcification in a patient after massive transfusion #lung #pathology #MedEd

At frozen section, what do you do with tumorlets at a parenchymal margin in a resection for carcinoid tumor? The best approach is to discuss with the surgeon. #lungpath #frozensection #pathology #thoracicpath

Smoking-related interstitial fibrosis, but if the patient has clinically and radiologically evident interstitial lung disease, clinicians would call this respiratory bronchiolitis with fibrosis interstitial lung disease... so confusing :-0

Interstitial lung diseases are challenging to diagnose. Recently, some terminologies were updated. Read more here: https://t.co/2jHs00zuVz Notably, DIP (now alveolar macrophage pneumonia) and AIP (now idiopathic DAD) are no longer used. #lungpath #lung #moffitt #lungILD

To Dr. Mukhopadhay last point, always look at the background lung in resections for tumors.

I agree @smlungpathguy. I used to make a fuss about these. Best to be descriptive, suggest exclusion of an infectious etiology, and provide a differential diagnosis to the clinicians. This case turned out to be incidental hypersensitivity pneumonitis, but that's the exception.

What to do with ill-formed interstitial granulomas on lung resections for malignancy? When are interstitial mononuclear inflammatory cells too numerous? (Same case, away from tumor) #moffitt #moffittpath #lungpath #moffittpathology

Academic life means you’re either working on your paper, thinking about your paper, avoiding your paper, feeling guilty for not working on your paper, or dreaming about working on your paper. #gupath #pathology @GU_Path_Society @IntSocUropath
