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! 😆🔬

🧩 Biphasic: dendritic blue nevus + cellular ovoid/spindle component

@awoke1971 I would say it’s useful, works even for crtical diagnostically challenging cases with good sensitivity unless it’s borderline expression or it’s discordant clinicopathologic presentation. But if it doesn’t work for you, then you absolutely shouldn’t be using the stain :)

I just gave a lecture about this.
This is bullous pemphigoid: IgG antibodies against 180, 230 or p200 kDa antigens within the DEJ (hemidesmosome) and it looks like this: subepidermal inflammatory eosinophilic bulla.

🔬 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−

🟡 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.
