Pyogenic granuloma (lobular capillary hemangioma) of the colon -- does it exist? If it does, here's an example. bit.ly/2YYhfFM #pathology #gipath

This is a nice example of a gastric pyloric gland adenoma with high grade dysplasia. The patient had autoimmune gastritis.

Isn't that cute - a odd colonic mucosal leiomyoma confined to the mucosa. Unlike most colorectal leiomyomas that straddle the muscularis mucosa! #GIpath

Following up on the case from 2 days ago, here's another liver showing amiodarone toxicity. This particular drug-induced injury can lead to cirrhosis, as seen here (regenerative nodules, extensive background fibrosis). #pathology #liverpath

ALWAYS fun and educational to do "Cyto-Histo Correlation" in Musculo-Skeletal/Soft Tissue lesions. "Pigmented Villonodular Synovitis (PVNS)/Tenosynovial Giant Cell Tumor, Ankle mass.

Thumb mass in an adult. What is your diagnosis? 📸: Tracy Halvorson #IowaPath #BSTPath #PathTwitter

Nothing exotic - an nice inflammatory fibroid polyp involving the colon.

A nice cytomegalovirus (CMV) gastritis. It's interesting that it often infects gastric epithelium rather than endothelium.

This is a pretty colonic granular cell tumor. They tend to have nuclear enlargement but a good outcome.

The lowly PAS stain is much more useful than the Ki-67 in confirming that the severe changes in this gastric antral biopsy are reactive - the mucin surface is nicely intact! Reference: PMID: 32841414; PMCID: PMC9281539.

Just crazy. I had an emergency Telemedicine consultation request from a new patient yesterday. I do not do emergency consultations on Telemedicine as I do not see new patients on Telemedicine. But this young man's father was my patient. He had advanced liver disease and liver

Antibiotics are the top causes of idiosyncratic drug-induced liver injury 🏆 = Amoxicillin-clavulanate doi.org/10.1056/nejmra…

This leiomyosarcoma has spread to bone from a retroperitoneal primary. #UMiamiPath

Poorly differentiated lung carcinoma with pleomorphic tumor giant cells. See keratin and TTF1 below. SOX10, CD45, CD43 negative. Thank goodness for IHC. #ThoracicPath
