Differential Diagnosis

• Melanoma • Seborrheic keratosis • Dermatofibroma • Blue nevus • Spitz nevus • Basal cell carcinoma

Key Learnings

• Common mole — benign neoplasm of melanocytes (nevus cells) • Types by location: junctional (flat), compound (raised, pigmented), intradermal (dome-shaped, less pigmented) • Maturation sequence: junctional → compound → intradermal (Unna-Abt maturation) • Normal adults have 10-40 moles • >50 nevi or >5 atypical nevi = increased melanoma risk • ABCDE criteria for monitoring
