The iPhone is as much an admirer of fibrin thrombi on a silver stain as I am. #PathSky

I found a “cool S” in some urine cyto #PathSky

I post a couple of FISH photos and now I’m getting targeted ads for fluorescence microscopes 🤷🏼‍♀️ #PathSky

Jerad Gardner a major draw card for IAP-AUS but wouldn’t it be great if he joined Bsky! #PathSky

MDM2 FISH, so amplified the cells look like opals. #PathSky

As a general rule, subcut administration of tablets is not an effective treatment for anything. #PathSky

This is obviously not fit for actual publication but I am (still, & hopefully eternally) amazed I can look down a microscope and see how many copies of a gene there are. #PathSky

High power view, classic spaghetti and meatballs appearance (apologies I think I absorbed that description from Jerad Gardner). ➡️ Elastofibroma

Scapula lesion #PathSky Somewhat ill defined, dense collagenous stroma with abnormal elastin fibres.

And this is the SMARCA4, showing loss in the tumour with retained expression in adjacent tissue.

Dr Tatiana Hitchen @txhitchen.bsky.social · 22/04/2026

So far, so metastatic. Sheets of cells, doesn’t have the discohesion I’d expect for melanoma or lymphoma but high grade and poorly differentiated so anything possible.

Dr Tatiana Hitchen @txhitchen.bsky.social · 22/04/2026

A conundrum of a case from last year. Large brain lesion. No known hx of malignancy. No definite lesions on imaging elsewhere. Minimal hx provided in general. Frozen and paraffin sections: malignancy sharply demarcated from normal glial tissue. Does not look like a primary brain lesion. #PathSky

BerEP4 ➡️ Clear cell variant of BCC.

Dr Tatiana Hitchen @txhitchen.bsky.social · 22/04/2026

Positive for p40. Doesn’t look squamoid and no overlying dysplasia… negative for SOX10, MelanA, AR, CEA, EMA, PAX-8.

Dr Tatiana Hitchen @txhitchen.bsky.social · 22/04/2026

High power view. Some mucin in the nests. Small, hyperchromatic nuclei, clear cytoplasm.

Dr Tatiana Hitchen @txhitchen.bsky.social · 22/04/2026

One of many skin lesions removed. Standard level of Australian solar elastosis. Invasive nests, vague peripheral palisading. #PathSky

Dr Tatiana Hitchen @txhitchen.bsky.social · 16/04/2026

Mostly cartilage, with a central fatty core, some invaginated respiratory epithelium.

Dr Tatiana Hitchen @txhitchen.bsky.social · 16/04/2026

Endobronchial lesion, reasonably chunky, somehow an “incidental” finding. #PathSky

Metastasis in motion. Tumour tracking towards the already pretty chockers lymph node.

Why on earth would I want to know about uterine cervicitis or cervicitis with that search phrase? Is this the new dumbing down of PubMed?

The only cute thing about this case on my desk. #PathSky

Ok, ok. Here’s the twist - here’s the patient #pathsky #PathSky #dermpath

Micro - a bit unexpected? Subcut as anticipated however appears to be an adnexal cyst lined containing numerous hair follicles. Mitotically active!!

Dr Tatiana Hitchen @txhitchen.bsky.social · 11/09/2025

Cut surface showed a cystic lesion filled with grey caseous material. Expected to be epidermal inclusion cyst

#PathSky #dermpath Subcutaneous neck lump, present for 3+ years, slow growth. Macro: 40mm. Appears encapsulated. Unusually well excised!

#PathSky Biopsy with gastritis on scope. Epithelial stripping, dense inflammatory infiltrate in the lamina propria, and thick subepithelial collagen band highlighted on trichrome -> collagenous gastritis. No significant neutrophil population and H. Pylori negative.

#PathSky Ulcerated skin lesion. Sheets of immature cells, mitoses +++, eosinophilic myelocytes (eosinophilic granular cytoplasm); MPO and CD43+ Haem team is very good and never fails to give the key history of AML.

Gratuitously posting this because I think kidney tumours are rewarding. Chromophobe RCC, plant-like cell walls and wrinkled nuclei. Very pretty staining for Hale’s colloidal iron. (Tumour was 133 mm!) #PathSky

PET-avid 🫁 lesion, hx of SCC elsewhere, biopsied. #PathSky

#PathSky Not only can you not ever trust invasive lobular breast cancer, you also DEFINITELY can’t trust micropapillary breast ca. Lymph node I initially thought was clear - with benefit of hindsight and AE1/AE3*, I revised this to ITCs. *ordered b/c I personally don’t trust micropap anything
