Fungal hyphae, PAS stain, lung biopsy Prior A. fumigatus on cultures Common things are common! #pathsky How to report? See: journals.sagepub.com/doi/abs/10.1...

Miliary lung disease occurs when a massive number of pathogens break out of an initial infection site, travel through the bloodstream, and blanket the lungs with thousands of tiny, millet-seed-sized spots #pathsky #yalerosenslidecollection

To open 2026, here is one of the rarest findings in a lung biopsy: fruiting body of Rhizopus (confirmed by PCR) #pathology #pulmpath #pathbugs #pathsky To read how these fruiting bodies differ from those of Aspergillus, click here: journals.sagepub.com/doi/10.1177/...

This fungal yeast was called Histoplasma on biopsy. This diagnosis was later confirmed by cultures. How often does this approach go wrong? #pathsky #idpath Read more here in @IJSPjournal : journals.sagepub.com/doi/10.1177/...

Sanjay Mukhopadhyay @smlungpathguy.bsky.social · 04/12/2025

This fungus looked exactly like Aspergillus but turned out to be Pseudallescheria (by microbiologic cultures). How should such cases be worded? Read more here in Int J Surg Pathol: journals.sagepub.com/doi/10.1177/... #pathsky #fungal #idsky #pathology #pulmpath

Fungal hyphae are more tricky to diagnose by pathology alone than yeasts See detailed discussion here: journals.sagepub.com/doi/10.1177/... #pathsky #fungal #pathology

Lymphangioleiomyomatosis: 1. Yet another misnomer in #pulmpath 2. PEComatous proliferations in walls of lung cysts 3. ALWAYS consider in women with bilateral lung cysts, recurrent pneumothoraces, tuberous sclerosis or renal angiomyolipoma 4. VERY IMPORTANT for boards #pathsky

Learn to differentiate fibroblast foci (this image) from fibroblast plugs (Masson bodies), or you will never learn to diagnose UIP and forever be "correlating" with CT findings. Don't misdiagnose UIP as organizing pneumonia! #pathology #pulmpath #uip #pathsky

PGY1s, you will learn about special stains that help to pick out microorganisms (AFB, GMS, PAS). But remember that many bugs are also visible on routine stains such as H&E and pap (used in cytology, shown here). Arrow: Histoplasma yeasts (dots) within a large histiocyte #pathsky

PGY1s: the "cribriform" growth pattern occurs in many cancers including adenoid cystic carcinoma and prostate cancer. It results when many small glands are packed together back to back into a sieve-like collection of lumens. From Latin (cribrum = sieve) #pathology #pulmpath #pathsky

How pathologists tell benign from malignant has always fascinated me. Is the lesion in these images (lets's assume it's a biopsy of a lung mass) benign or malignant? Please explain your thought process so others can learn.
