In this episode of Dermatology Discussions, we take a clear, pathology-focused look at the histopathology and pathogenesis of hyperkeratosis, using a simple “skin factory” analogy to explain normal epidermal differentiation. We break down the key differences between orthokeratosis and parakeratosis, including: 🔬 Normal epidermal differentiation and the stratum corneum 🧱 The “skin factory” model of keratinocyte maturation 🧬 Orthokeratosis vs. parakeratosis 🔍 Granular layer changes and nuclear retention 🩺 Clinicopathologic correlation 📚 Classic histologic findings in psoriasis ⚡ Munro microabscesses and regular acanthosis 💊 How these histologic mechanisms relate to psoriasis treatment 🎯 Board Exam Focus A high-yield review for dermatology residents, medical students, pathology learners, and healthcare professionals preparing for examinations or strengthening their dermatopathology fundamentals. Key takeaway: Orthokeratosis = anucleate corneocytes. Parakeratosis = retained nuclei in the stratum corneum.
