Today is the last day of my last CORE AP rotation. No more noise... 🥰🥰🥰 Next year, it will be wherever you want it to be!

I’m excited to share that The Pathologist has included our Warty ART in its artwork series 🧩✨ Please feel free to circulate the link below 🔗👇😊 I’m very grateful to be included. thepathologist.com/issues/2026/ar… #dermpath #dermatology #dermatologia #dermtwitter #pathology #pathologists #pathTwitter @pathologistmag

Let’s start the morning with pressure lesions! This one is rare but worth knowing—it's much more common on the ear. 🛌Chondrodermatitis Nodularis Nasi (CNN): 👃 Painful, tender small nodule on the nasal tip/ala ⚠️ Central ulcer with wedge-shaped dermal ischemic degeneration 🧩 Underlying degenerative cartilage-chondrocyte dropout/fissuring 🔄 Pressure-induced ischemic repair pattern with granulation tissue — histologically identical to Chondrodermatitis nodularis helicis #dermpath #dermatology #dermatologia #dermtwitter #pathology #pathologists #PathTwitter

🔬 Perivascular Myoid Tumors: SMA+, desmin-, caldesmon- 👉 fake smooth muscle tumors! 1.Biphasic pattern + hemangiopericytoma-like vessels➡️Myofibroma (image attached 👇) 2.Concentric perivascular wrapping without zonation Uniform onion-skin architecture ➡️ Myopericytoma 🔬🔬True smooth muscle differentiation: SMA+, desmin+, caldesmon+ Think "Thick"-walled muscular vessels ➡️Angioleiomyoma #dermpath #dermatology #dermatologia #dermtwitter #pathology #pathologists #pathTwitter

🔬 Myopericytoma 🫡Typically presents as a well-circumscribed dermal/subcutaneous nodule 🩸Characteristic perivascular concentric (“onion-skin”) growth around thin-walled vessels 🤥Not a true smooth muscle tumor (unlike angioleiomyoma) 🪴Bland cytology in benign lesions 🧠 Dxx ➡️ Angioleiomyoma — Fascicular smooth muscle bundles, thicker vessel walls, diffusely desmin-positive ➡️ Glomus tumor — Uniform round cells, no concentric spindle growth ➡️ Myofibroma — Biphasic pattern with zonation #dermpath #dermatology #dermatologia #dermtwitter #pathology #pathologists #pathTwitter

🧵Collagenous Dermatofibroma 🌳 Epidermal induction with overlying acanthosis and basal hyperpigmentation 🌀 Poorly cellular interlacing spindle and histiocytic proliferation in the dermis 🧵 Prominent dense, hyalinized (sclerotic) collagen replacing much of the storiform architecture 🎯 Peripheral collagen trapping with entrapment of thickened dermal collagen bundles 🧫 Occasional peripheral reactive lymphoid aggregates #dermpath #dermatology #dermatologia #dermtwitter #pathology #pathologists #pathTwitter WSI: aisight.pathai.com/unaffiliated/s…

Where is the AI everyone keeps promising? 🤖 ~1/2 of a 2 × 2 mm area was exhausting 😵‍💫 Too many mitoses! 🔥🤬🫡😡#pathologists #pathology #pathTwitter #dermpath #dermatology #dermatologia #dermtwitter

@redsnapperpath @redsnapperpath we hope you can come sooner than later to study some derm 🥰🥳😆

@CakePath i have to be honest, i am not sure i would get past USA border security

Happy Saturday 😊 - Macular amyloidosis! 🩺 Rippled hyperpigmented macules (often pruritic) on upper back/extensor arms; associated with chronic friction. 🔬 Scant papillary dermal amyloid with basal hyperpigmentation ± pigment incontinence; minimal inflammation. 🧪 Ancillary: Congo red+ (often weak), PAS+, ± Thioflavin T; keratinocyte-derived amyloid, not AL/AA → no systemic amyloidosis. #dermresident #pathresident #pathTwitter #dermpath #dermatology #dermatologia #dermtwitter

@redsnapperpath Nice to see you, Dr. Osmond! Hope you are rocking the Dermpath!!! Come to USCAP!!!

@CakePath nice summary 👍

@JMGardnerMD you may also have LS starting out in that papillar/superficial dermis of yours 😇☺️🙃

Cute ❤️ in the skin due to tangential/oblique sectioning. What layer of the skin is the ❤️ in? Answer ✅ youtu.be/jQHPlTxpgVI?t=… #pathology #pathologists #pathTwitter #dermpath #dermatology #dermatologia #dermtwitter

@JCandidoXavier Cool 😎

Not every cystic invagination of the epidermis represents an epidermoid cyst. 😬 Tiny pilar sheath acanthoma: note the crater filled with keratin and the solid lobules of eosinophilic cells radiating from it. #path #pathology #dermpath #dermatology

@JLHornick Show off !

My daughter made pozole 🌶️

@JessicaATexere @pathologistmag I am always interested in working with THE pathologist 🥰😇😃😊

@CakePath Love this @CakePath 👏 I'd be thrilled to include this in @pathologistmag 2026 image feature if you're interested? Let me know - happy to provide more info 😁

@MeredithKHerman Dermpath - the path to rule them all..😇

@CakePath Sketchy but pathology???
