Final answer:
A focal wavelike motion on palpation indicating pus collection characterizes an abscess, while skin thickening from edema and inflammation might be described as induration. Furuncles and carbuncles are different types of pus-producing skin lesions, and edema is the swelling in tissues due to water accumulation.
Step-by-step explanation:
The sensation of a focal wavelike motion on palpation that indicates pus collection is a characteristic finding of an abscess. An abscess is a pus-filled lesion that forms due to an infection. The skin thickening from edema and inflammation does not have a technical term provided in the context given, but in general, it could be referred to clinically as induration which often accompanies infections or inflammation.
Information about types of skin lesions describes various presentations of skin infections and inflammations. Furuncles and carbuncles are examples. A furuncle, or boil, is a pus-producing infection that stems from an infected hair follicle, while a carbuncle is a deeper, more extensive lesion formed from multiple furuncles. Edema, another important term from the information, refers to the accumulation of excess water in the tissues causing swelling. It can be detected through the presence of a persistent indentation after pressing on the swollen area, which is termed pitting.
