Abstract
A 10-year-old girl with a history of blastic plasmacytoid dendritic cell neoplasm, a rare malignancy in children, presented with recurrent skin eruptions beginning while on maintenance chemotherapy, including mildly pruritic skin-colored plaques, tender indurated nodules, and violaceous bound-down plaques. This case highlights an unusual presentation of relapsed blastic plasmacytoid dendritic cell neoplasm on chemotherapy, with skin lesions providing important clues to the progression of systemic disease.

Abstract
Large difficult to heal ulcers of various etiologies carry a high morbidity and mortality rate. Becaplermin is a recombinant platelet-derived growth factor approved for treatment of diabetic ulcers. In this two-case series, we report the use of becaplermin in the treatment of ulcers due to (i) calciphylaxis, an often fatal condition resulting from systemic calcification and thrombosis of vessels and (ii) pyoderma gangrenosum (PG), a neutrophilic dermatosis. We also report that topical collagenase worsened PG ulcers, consistent with pathergy. Becaplermin can be used to help treat ulcers resulting from calciphylaxis and PG. These encouraging results lend support for the utilization of becaplermin in the treatment of nondiabetic chronic ulcers of various etiologies.
