Pyoderma gangrenosum (PG) is an uncommon neutrophilic dermatosis characterized by rapidly progressive painful ulcerations and difficult diagnosis.1,2 Histopathologic findings are frequently nonspecific, making clinicopathologic correlation essential.3,4
Drug-associated PG has become increasingly recognized with the expanding use of biologic therapies.5 Secukinumab, an interleukin-17A inhibitor widely used for psoriasis, has rarely been associated with paradoxical PG.6, 7, 8, 9, 10 We report a probable case of paradoxical PG associated with secukinumab in a patient with severe plaque psoriasis and exuberant scalp involvement.
