To open 2026, here is one of the rarest findings in a lung biopsy: fruiting body of Rhizopus (confirmed by PCR)

To read how these fruiting bodies differ from those of Aspergillus, click here:

This fungus looked exactly like Aspergillus but turned out to be Pseudallescheria (by microbiologic cultures). How should such cases be worded?

3 thoracic pathologists discuss pathology of mesothelioma

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

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!

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

❌Adenocarcinoma
Cohesive flat sheets or dense, glandular, acinar, or papillary architecture with cells orientated to edges.
Nuclei: central, round/oval, large nucleoli & fine chromatin
Cytoplasm: eccentric, well-defined, and one to multiple vacuoles

✅Schwannoma
slow-growing solitary tumor in posterior mediastinum (paravertebral)
spindle cells with ovoid / buckled nuclei with tapered ends
bizarre shapes, ancient change, and pseudoinclusions may be seen
paranuclear vacuoles not seen, seen in leiomyoma

❌Meningioma
Most lesions are peripheral and localized to the lung
Well circumscribed, solid proliferation
Bland tumor cells growing in whorls and lobular nests

Schwannoma?
Meningioma?
Or just some histiocytes?
