It's just a cute hibernoma (lipoma of brown fat); a colleague was worried about it because of the rich vascularity. Brown fat is similarly chock full of little capillaries.

Check out this succinate dehydrogenase deficient gastrointestinal stromal tumor! This one had the classic plexiform pattern. The usual risk assessment schemes do not apply to these! PMID: 27340750.

Gulp. Thank goodness for years as a (bad) cytopathologist; the sample, labeled "mass adjacent to the trachea", was concerning for chondrosarcoma. Mercifully, tyrosine crystals suggested parotid pleomorphic adenoma. The immunohistochemical results were reassuring; S100 also +.

A lovely example of colonic granular cell tumor. These are more common in the right colon than elsewhere in the colon.

Abrupt transitions between non-dysplastic and dysplastic epithelial cells are a diagnostic clue for distinguishing dysplasia from reactive epithelium. This image is from the gallbladder.

Pyloric gland adenoma in uninflamed gastric body. There is an association with autoimmune gastritis (pyloric metaplasia progressing to pyloric adenoma) but this patient does not have it. Note the appearance of the surface of the adenoma versus the adjoining foveolar epithelium.

Needle biopsy of a gastric glomus tumor; in this location, a neuroendocrine (carcinoid) tumor would be considered. These lesions sport various molecular alterations, but immunohistochemistry can confirm the diagnosis. Iwamura R, et al. PDGFRB and NOTCH3 Mutations are Detectable in a Wider Range of Pericytic Tumors, Including Myopericytomas, Angioleiomyomas, Glomus Tumors, and Their Combined Tumors. Mod Pathol. 2023 Mar;36(3):100070. PMID: 36788105.
