Derm: Basal Cell Carcinoma: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Basal Cell Carcinoma (BCC)🎧 A high-yield breakdown of this common, slow-growing skin cancer – perfect for MSRA revision and clinical insight.🧠 Key Learning Points📌 DefinitionBasal Cell Carcinoma (BCC) is a slow-growing, locally invasive skin cancer arising from basal cells in the epidermis.🧠 Key traits: Common, rarely metastasises, but can cause extensive local tissue damage if untreated.📌 Causes & Risk Factors• Chronic UV radiation exposure (sun or tanning beds)• Fair skin, history of severe sunburns (especially in childhood)• Older age, male sex• Genetic syndromes: Basal Cell Naevus Syndrome (Gorlin), Xeroderma Pigmentosum• Immunosuppression (e.g. post-transplant, HIV)• Prior radiotherapy or arsenic exposure🧠 Mnemonic: “SUN-GENES” – Sunlight, UV, Nevus syndrome, Genetics, Elderly, Neoplasm history, Skin type I📌 Pathophysiology• UV → DNA damage in basal cells → loss of cell cycle control → uncontrolled cell division• Tumour grows locally into skin and deeper structures• Rarely spreads systemically📌 Symptoms• Classic: Pearly/translucent nodule with rolled edge and telangiectasia• May ulcerate, crust, bleed or mimic a non-healing sore• Types: • Nodular (most common) • Superficial (red, scaly patch on trunk) • Morpheic (scar-like, poorly defined, more aggressive) • Pigmented (can mimic melanoma) • Basosquamous (mixed features)🧠 Buzzword: Rodent ulcer = indurated ulcer with a destructive edge📌 Differential Diagnosis• Melanoma• Squamous Cell Carcinoma (SCC)• Seborrhoeic keratosis• Psoriasis or eczema (superficial BCC)• Lupus vulgaris, lichen planus📌 Diagnosis• Clinical suspicion based on lesion features• Dermatoscopy can aid diagnosis• Skin biopsy = gold standard (shave or punch)🧠 Histology tip: Look for basaloid cells, hyperchromatic nuclei, clefting between tumour islands and stroma📌 Management• Surgical excision (mainstay) – 4mm margin• Mohs surgery – for facial, recurrent, or morpheic BCC• Cryotherapy – for superficial BCC• Topical therapy (for superficial): • Imiquimod • 5-FU (fluorouracil)• Photodynamic therapy (PDT)• Radiotherapy – for elderly or unfit patients🧠 Recurrent BCCs = harder to cure → treat right first time🧠 Refer under 2-week rule if high-risk site or suspicious growth📌 Complications• Local destruction of nearby tissue• Cosmetic disfigurement• Increased risk of: • New BCCs • SCC • Melanoma • Rarely: non-skin cancers (e.g. lung, breast, thyroid)📌 Prognosis• Excellent if diagnosed early and treated• Very low metastasis rate• Risk of recurrence or developing new skin cancers remains high🧠 Key message: A BCC diagnosis is a lifelong red flag for skin cancer vigilance📎 More MSRA Resources for Basal Cell Carcinoma📝 Revision Notes:https://www.passthemsra.com/topic/basal-cell-carcinoma-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/basal-cell-carcinoma-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/basal-cell-carcinoma-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/basal-cell-carcinoma-rapid-quiz/🧪 Topic Quiz:https://www.passthemsra.com/quizzes/basal-cell-carcinoma/🎓 Full Dermatology Course:https://www.passthemsra.com/courses/dermatology-for-the-msra/📣 Explore full revision guides, quizzes, flashcards, and more athttps://www.passthemsra.comHashtags#MSRA #MSRARevision #MSRATextbook #MSRAFlashcards #MSRAQuiz #MSRAQandANotes #MSRAAccordions #BasalCellCarcinoma #Dermatology #RodentUlcer #SkinCancer #MultiSpecialtyRecruitmentAssessment #PassTheMSRA
