Derm: Keloid scar: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Keloid Scars🎧 Dive into this high-yield episode where we break down everything you need to know about keloid scars – a niche but frequently tested dermatology topic for the MSRA.🧠 Key Learning Points📌 Definition• Keloid scars are raised, thickened areas of fibrous tissue that extend beyond the original wound margins.• They are benign but may cause significant cosmetic and symptomatic concerns.📌 Causes & Pathophysiology• Result from overproduction of collagen during wound healing.• Linked to genetic predisposition and dysregulation in pathways like TGF-β signalling.• Excessive fibroblast activity and lack of ‘stop signals’ lead to ongoing scar tissue formation.• Often triggered by skin trauma, surgery, burns, piercings, acne, or inflammation.📌 Risk Factors• Family history of keloids• Darker skin tones (more common in African, Hispanic, and Asian descent)• Ages 10–30, with peak incidence in young adults• Common anatomical sites: earlobes, shoulders, sternum, upper back, cheeks📌 Symptoms• Firm, raised, rubbery scar tissue• Often itchy, sometimes tender or painful• May be red, pink, or hyperpigmented compared to surrounding skin• Frequently extends beyond the initial injury• Can restrict movement if over joints📌 Differential Diagnosis• Hypertrophic scar (raised but stays within the wound boundary)• Dermatofibroma• Dermatofibrosarcoma protuberans (rare)• Keloidal acne or granulomas📌 Diagnosis• Primarily clinical – based on history and characteristic appearance• Biopsy only if diagnosis is uncertain or malignancy suspected📌 Management🎯 Goal: Improve appearance and relieve symptoms• Silicone gel sheeting – reduces scar height and improves texture• Intralesional corticosteroids (e.g. triamcinolone) – first-line for active or symptomatic keloids• Cryotherapy – especially helpful for small keloids, often combined with steroids• Laser therapy – can reduce pigmentation and flatten lesions• Pressure garments – useful after excision or in earlobe keloids• Surgical excision – only in combination with preventative therapy, as recurrence is high• Post-op radiotherapy or 5-FU injections – for resistant or recurrent cases📌 Prevention• Avoid unnecessary trauma (e.g. piercings or tattoos in high-risk individuals)• Early treatment of acne and inflammatory skin issues• Preventative strategies post-surgery: - Careful closure along skin tension lines - Immediate steroid injections - Pressure therapy or silicone use📌 Prognosis• Chronic condition with high recurrence rate• Symptoms can impact quality of life• No systemic complications, but significant cosmetic and psychological effects• Specialist referral often needed📎 More MSRA Resources for Keloid Scars📝 Revision Notes:https://www.passthemsra.com/topic/keloid-scar-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/keloid-scar-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/keloid-scar-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/keloid-scar-rapid-quiz/🧪 Topic Quiz:https://www.passthemsra.com/quizzes/keloid-scar/🎓 Full Course:https://www.passthemsra.com/courses/dermatology-for-the-msra/📣 All resources are part of the Dermatology for the MSRA course at PassTheMSRA.com.Find full revision packs, MCQs, flashcards and more at:👉 https://www.passthemsra.com#MSRA #MSRARevision #KeloidScar #DermatologyMSRA #MSRAFlashcards #MSRAQandA #MSRAQuiz #MSRALearning #KeloidsMSRA #PassTheMSRA #FreeMSRARevision #HighYieldDermatology
