All of the lesions pictured, namely, macules, papules, erosions, and crusts, resulted from external trauma, to wit, excoriation, the condition being factitious entirely.

The blotchy patches and plaques shown here are secondary to rubbing vigorously.

Ill-defined zone of lichenification, evidenced by thickening of skin whose markings are accentuated, resulted from persistent, firm rubbing; the hemorrhagic crusts derived from animated scratching.

All of the changes depicted, i.e., hemorrhagic crusts atop papules and scale-crusts that cover ill-defined plaques punctuated by fissures, result from scratching and rubbing.
