These are extremely common lesions, particularly in the elderly. They result from very minor trauma which the patient may not even remember. The one depicted here is very dark. Lesions are ecchymoses (essentially bruises), and can be any shade from blue to black, depending upon the age of the lesion. Often, many are present on each arm, the characteristic location. They heal with a whitish, irregularly shaped scar, called a stellate pseudoscar.
