Rooky Tuesday! 🔬 Warty dyskeratoma 😎🫡💪 🥣 Cup-shaped, keratin-filled follicular invagination ✂️ Suprabasal acantholysis with villi 🎯 Dyskeratosis: corps ronds & grains 🔍 Differentials • Acantholytic dyskeratotic acanthoma: lacks follicular cup • Darier/Grover disease: clinical distribution • Acantholytic SCC: atypia & invasion #pathology #pathologists #pathTwitter #dermpath #dermatology #dermtwitter

🔥 Hot off the press! We’re pleased to share two cases of iododerma, both first diagnosed at #MDACCPath #dermpath. This peculiar entity may be underdiagnosed due to a lack of recognition. The article is open access, so check it out! 😆🔬 onlinelibrary.wiley.com/doi/…

🔬 Granular cell tumor — high-yield pearls 📍 Clinical • Solitary, slow-growing, firm nodule • Head/neck common, especially tongue 👅 • Usually benign; malignant tumors are rare 🧫 Histology • Poorly circumscribed, infiltrative dermal/subcutaneous neoplasm • Large polygonal cells with abundant coarse eosinophilic granular cytoplasm • 🔥 Granules = numerous intracytoplasmic lysosomes/autophagolysosomes • PASD+, diastase-resistant granules (do you know anybody who does it?) • Cells dissect between collagen bundles and may involve nerves or skeletal muscle • Overlying pseudoepitheliomatous hyperplasia may mimic SCC ⚠️ 🧬 IHC • Conventional granular cell tumor = Schwannian, S100+/SOX10+ • Non-neural granular cell tumor = non-Schwannian, S100−/SOX10− #pathology #pathologists #pathTwitter #dermpath #dermatology #dermtwitter

🟡 Verruciform xanthoma 👀 Often looks like a wart clinically: solitary, slow-growing, verrucous/papillomatous plaque or nodule, classically oral or anogenital. 🔬 Histo: verrucous/psoriasiform hyperplasia + hyperparakeratosis ± neutrophils. 🫧 Don’t miss the clue: foamy macrophages packed superficially in the papillary dermis between rete ridges. 💡 Wart-like lesion + superficial foam cells → think verruciform xanthoma. #pathology #pathologists #pathTwitter #dermpath #dermatology #dermtwitter

Going into derm? This one’s for you! 👇 Skip it if you’re just derm-curious or a total beginner 🙂 🔬 Histo: Psoriasiform dermatitis (see below). 👀 Clinical: they really want eczema! 🧠 Beyond morphology: Can we really see everything on H&E? How many stains/ancillary are enough? There is always some sponge around the corner! 🧬 Cytokine ISH : NOS2 and IL17 were positive, supporting psoriasis and consistent with the histopathology. IL13 and IFNG were negative (attached table for expression patterns). 🔬 Histo is king—but not the whole kingdom anymore! #pathology #pathologists #pathTwitter #dermpath #dermatology #dermtwitter
