Dermabrasion = procedure to remove skin scars with abrasive material (like sandpaper). Diaphoresis = profuse sweating. Edema= swelling due to accumulation of fluid. Emollient = agent to soften or smooth skin. Complementary Terms #4 Induration = abnormal hard spot. Jaundice= yellow looking skin. Keloid= overgrowth of scar tissue. Macule = flat, colored spot on the skin. Nevus= pigmented area on skin, birthmark. Papule= small solid skin elevation, pimple. Pruritus = severe itching. Pustule= elevation, containing pus. 8
