Neoplastic and emergency dermatology focus on timely identification of skin cancers and acute, potentially life-threatening skin conditions, while occupational and aesthetic dermatology address workplace exposures and cosmetic interventions. This volume integrates tumor recognition and management with pragmatic guidance for work-related dermatitis and elective aesthetic procedures. Chapters provide clinic-ready algorithms for biopsy, staging, and referral, along with prevention strategies for occupational skin disease. Emergency sections cover toxic epidermal necrolysis, anaphylaxis with cutaneous signs, and acute vasculitis, emphasizing stabilization and escalation. Procedural appendices summarize when to intervene and when to refer for specialty care. The book suits residents, ER physicians, and clinicians performing outpatient dermatologic procedures.
