Describing soft tissue lesions
On a piece of scrap paper write a description for each of the 4 lesions you see below. After you have written down your description, check your answer by clicking on the arrow on the answer box under each image. The answers are very complete, so don't worry that you missed some of the details. The important part is when you read the answers, be certain you can see everything described in the answer. Look for yourself improving as you go from 1 to 4.
