Pityriasiform drug eruption associated with venetoclax for acute myeloid leukaemia.

Abstract

Venetoclax is a targeted antileukaemic therapy that has emerged as the primary treatment of acute myeloid leukaemia in patients of advanced age or who would otherwise be ineligible for standard chemotherapy. Despite the documented evidence of cutaneous side effects of venetoclax, few reports have clarified presenting cutaneous features beyond the descriptors 'rash' and 'pruritus'. In this report, we describe the development of a pityriasiform drug eruption following venetoclax-based induction therapy for acute myeloid leukaemia. This study provides further evidence to characterise the range of cutaneous adverse events that are associated with venetoclax-based therapy. Further studies are needed to elucidate the epidemiology and pathophysiology of venetoclax-induced cutaneous toxicities.
