⚕️ FREE MSRA PODCAST – Guttate Psoriasis🎧 A clear, high-yield breakdown of this immune-mediated skin condition triggered by strep – perfect for exam prep and real-life diagnosis.🧠 Key Learning Points📌 DefinitionGuttate psoriasis is an acute form of psoriasis characterised by small, drop-shaped red scaly lesions, often appearing after a streptococcal throat infection.📌 Causes & Risk Factors• Recent streptococcal throat infection (typically 2–4 weeks prior)• Younger age group – commonly children, teens, young adults• Genetic predisposition – family history of psoriasis• Triggers: stress, skin injury (Koebner phenomenon), medications• Drugs: antimalarials, lithium, NSAIDs, beta blockers🧠 Mnemonic: “STREP DROP” – Strep infection, Teens, Rashes, Erupt Post-infection📌 Pathophysiology• Immune overactivation → rapid skin cell proliferation• Skin cells build up too fast → red, scaly papules• Triggered by streptococcal antigens activating T cells in genetically susceptible individuals📌 Symptoms• Sudden eruption of 1–10 mm red, scaly papules• Often mildly itchy• Distribution: trunk, proximal limbs, scalp• Palms/soles rarely involved• Nail changes usually absent – key distinction from plaque psoriasis📌 Differential Diagnosis• Plaque psoriasis• Pityriasis rosea (look for herald patch)• Tinea corporis• Nummular eczema• Drug eruption• Viral exanthems• Secondary syphilis• Lichen planus• Cutaneous T-cell lymphoma• Pityriasis lichenoides📌 Diagnosis• Clinical – based on history (esp. recent sore throat) + lesion appearance• Consider ASO titre or throat swab to support strep link• Dermoscopy if needed to differentiate• Skin biopsy only in atypical/unclear cases📌 Management• Reassure: most cases resolve in 2–3 months• Topicals: corticosteroids, emollients, vitamin D analogues• Phototherapy (UVB) for widespread/resistant cases• Antibiotics only if active streptococcal infection is present• Tonsillectomy may be considered for recurrent strep-linked flares❗ Critical Exam Point: Antibiotics DO NOT treat the skin lesions📌 Complications• Progression to chronic plaque psoriasis• Recurrent episodes – especially after infections• Post-inflammatory pigmentation (hypo/hyper)• Rare: pustular or erythrodermic psoriasis (emergencies)• Iatrogenic issues from steroids/phototherapy (skin thinning, telangiectasia, etc.)📌 Prognosis• Excellent in many cases – complete resolution is common• Younger patients and high ASO titres = better prognosis• Monitor for chronic progression in some individuals📎 More MSRA Resources for Guttate Psoriasis📝 Revision Notes:https://www.passthemsra.com/topic/guttate-psoriasis-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/guttate-psoriasis-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/guttate-psoriasis-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/guttate-psoriasis-rapid-quiz/🧪 Topic Quiz:https://www.passthemsra.com/quizzes/guttate-psoriasis/🎓 Full Dermatology Course:https://www.passthemsra.com/courses/dermatology-for-the-msra/📣 All these resources are part of the Dermatology for the MSRA course at👉 https://www.passthemsra.comHashtags#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #GuttatePsoriasis #Dermatology #PassTheMSRA
