Atrophia maculosa varioliformis cutis.

We describe a case of atrophia maculosa varioliformis cutis (AMVC), a rare form of idiopathic facial macular atrophy. A biopsy revealed only a depression in the epidermis, probably caused by loss of dermal collagen. Because AMVC may be confused with scarring, and factitial disease may be suggested, it is important that this condition be recognized by the physician.
