CHAPTER 120 ■ MINOR LESIONS SARAH C CAVALLARO, TODD W LYONS GOALS OF EMERGENCY CARE A variety of minor lesions in children may prompt an emergency department (ED) visit Most visits are the result of acute injury, infection, or a combination of the two mechanisms (e.g., hair tourniquet, felon, paronychia) Some formerly quiescent abnormalities (e.g., thyroglossal duct cyst, pyogenic granuloma) become clinically apparent after rapid enlargement secondary to infection or trauma Alternatively, asymptomatic minor lesions (e.g., lipoma, pilomatrixoma) may be noted during the evaluation of an unrelated complaint Regardless of the presentation, a systematic approach is necessary for proper diagnosis and subsequent management of these lesions Although most “lumps and bumps” in children have a benign cause, the clinician should recognize lesions requiring emergent management, and understand the possibilities of associated systemic illness and future complications RELATED CHAPTERS Signs and Symptoms Lymphadenopathy: Chapter 47 Neck Mass: Chapter 48 Medical, Surgical, and Trauma Emergencies Dermatologic Urgencies and Emergencies: Chapter 88 Endocrine Emergencies: Chapter 89 Gynecology Emergencies: Chapter 92 Infectious Disease Emergencies: Chapter 94 Hand Trauma: Chapter 109 ENT Emergencies: Chapter 118 Procedures: Chapter 130 The Children’s Hospital of Philadelphia Clinical Pathway
