In hematology, the incidence of AZA\u2010induced cutaneous adverse events (AE) has been known to be relatively high, which has not been well recognized by dermatologists. Discontinuation of AZA can result in the deterioration of MDS disease activity. Therefore, on dermatological consultation, precise evaluation of AE severity and careful consideration is required for post\u2010AE medication management. To enhance our understanding of AZA\u2010induced cutaneous AE, we report four cases with two representative cutaneous AE subtypes and summarize the clinicopathological phenotypes and courses of the cases in the published work. Case 1, a 71\u2010year\u2010old man, developed neutrophilic dermatosis involving the dermis and subcutaneous tissue. The other three cases, a 75\u2010year\u2010old man, a 78\u2010year\u2010old woman and a 68\u2010year\u2010old man, presented injection\u2010site erythema associated with flare\u2010up reaction. Discontinuation of AZA was necessary for case 1 alone. The published work review delineated three major subtypes of AZA\u2010induced cutaneous AE: systemic cutaneous reaction, neutrophilic dermatosis type and erythematous type injection\u2010site reaction. Histologically, the first two subtypes are mostly characterized by neutrophil infiltration, while the third subtype presents lymphocytic cell infiltration. Neither AZA discontinuation nor intensive interventions were required for the erythematous type injection\u2010site reaction, while AZA termination or systemic treatments, represented by corticosteroid administration, were preferentially conducted for the systemic cutaneous reaction or the neutrophilic dermatosis type injection\u2010site reaction subgroup. These observations support the necessity of subtype\u2010dependent treatment strategies for the management of AZA\u2010induced cutaneous AE.<\/jats:p>","DOI":"10.1111\/1346-8138.15264","type":"journal-article","created":{"date-parts":[[2020,2,14]],"date-time":"2020-02-14T06:50:50Z","timestamp":1581663050000},"page":"363-368","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Cutaneous
