🩺 Diagnostic Challenge! A 68-year-old man presents with a pigmented scalp nodule, and the clinical impression is melanoma. 🖤 But is it really? 🤔

WHO 2026 Clarification on Immature Teratomas

Any amount of immature neuroepithelial tissue in a teratoma → diagnose as immature teratoma

Before calling it immature, rule out mimics:
- Cerebellar tissue (pic 1)
- Retinal tissue (pics 2 & 3; pic 3 was previously misdiagnosed as immature teratoma)
- Ependymal tissue (pic 4)

This is fat atrophy / pseudoneoplastic fat atrophy / serous fat atrophy / starvation-induced fat atrophy
Goes by many names. Important pitfall 🕳️to be aware of, as it may mimic malignancy, especially:
-> signet ring cell carcinoma (SRC)
-> liposarcoma
🔬clues to the diagnosis:
➡️well circumscribed & non-infiltrative (retains lobular configuration of mature adipose tissue)
➡️PanCK negative, S100+
✅In the image below, the continuity with non-atrophic fat gives away the benign nature of the process

The clinical context may be misleading (history of actual SRC), or helpful (no prior malignancy, history of chronic consumptive illness, anorexia nervosa, malnutrition, etc.)

Great short video by @JMGardnerMD on this -> https://t.co/p9AzBM1QQk
Recently put together series by @MdSuster et al. where they propose the name "pseudoneoplastic fat atrophy" to better highlight its potential to mimic malignancy.

Excellent diagnostic pitfall! 👏 Pseudoneoplastic fat atrophy can closely mimic signet-ring cell carcinoma, especially in patients with a history of colorectal cancer. #GIPath #Pathpitfalls

A 65-year-old patient undergoes a screening colonoscopy. A flat, 8mm polyp covered by a mucus cap is found in the ascending colon.
What's the diagnosis for this right-sided polyp?
A) Sessile Serrated Lesion (SSL)
B) Hyperplastic Polyp
C) Traditional Serrated Adenoma (TSA)
D) Tubular Adenoma

10 Years of iLovePathology!

What started in November 2016 as a small collection of learning resources for my students, as part of a flipped classroom approach, has now completed 10 years!

Over the years, I continued creating and sharing educational content on my YouTube channel and website, using few simple handwritten illustrations to explain pathology concepts.

Today, the channel has 297 educational videos covering various aspects of pathology for medical students!

The idea was simple when I started, and it remains the same even today — to make pathology easier to understand, particularly for the undergraduate medical student.

I'm glad that these resources have been useful not just to MBBS students, but also to paramedical students and some postgraduate students, both in India and elsewhere.

Ten years later, I still enjoy creating educational content whenever time permits. There is always something more to learn, teach and share!

If you have learnt something from iLovePathology over these years, I would love to hear your feedback and suggestions. They will help me improve the content further.

Thank you @JMGardnerMD @smlungpathguy @kriyer68 @pembeoltulu @ariella8 @adi_agnihotri @DrGeeONE @HermelinMD @KMirza @edusqo @_SaranyaS_
@archibhat3 and to everyone in this twitter/ X world who has been very supportive and part of this journey!

🌎🔬 The Network That Never Sleeps! 💙

Across continents and time zones, the global pathology community is united by an extraordinary spirit of generosity, curiosity, mentorship, and shared learning.

At any given moment, somewhere in the world, a pathologist is sharing a fascinating case, teaching a colleague, exchanging insights, or unraveling a diagnostic challenge.

Knowledge travels across time zones, keeping our community connected, inspired, and learning around the clock.

Together, we form a living network of knowledge, where every case shared, every question asked, and every lesson learned enriches us all.

🏆 Welcome to the October 2026 #PathTweetAward Compilation!

Join me in celebrating the wonderful educational contributions of pathologists from around the world. Each contribution strengthens this remarkable community and reminds us that the greatest value of knowledge lies in sharing it!

💙 A special thank-you to our dedicated screening judges:
