Abstract
The landscape of available therapeutic options for treatment of genitourinary (GU) cancers is expanding dramatically. Many of these treatments have distinct, sometimes severe, skin toxicities including morbilliform, bullous, pustular, lichenoid, eczematous, psoriasiform, and palmoplantar eruptions. Pruritus and skin pigmentation changes have also been noted. This review aims to synthesize dermatologic events observed with antibody drug conjugates, poly (ADP-ribose) polymerase (PARP) inhibitors, androgen receptor pathway inhibitors, tyrosine kinase inhibitors, immune checkpoint inhibitors, and the combination of these agents used for the treatment of GU cancers. It provides a guide on diagnosis and initial management of these rashes for medical oncologists.
