Hemorrhagic bullae were present within pre-existing atrophic lesions involving her abdomen, left flank, bilateral medial arms and antecubital fossae [Figure 1].
Punch biopsy of the left flank showing thinning of the epidermis with compact hyperkeratosis, degeneration of the basal layer, edema with the early stages of a subepidermal blister, and a band of homogenized collagen in the dermis (H and E, x100)
