Key clinical message: Hematopoietic neoplasms can cause adrenal infarction. In cases of thrombosis occurring at uncommon sites, it is necessary to consider evaluating for the JAK2V617F mutation, even in the absence of notable abnormalities in blood counts.
Abstract: Adrenal infarction, a rare ailment, has been sporadically linked to hematopoietic neoplasms. A 46-year-old male encountered left adrenal infarction, which coincided with a progressive rise in platelet counts. Subsequent diagnosis revealed myelodysplastic/myeloproliferative neoplasm-unclassifiable, featuring a JAK2V617F mutation. Simultaneously, the patient manifested multiple arteriovenous thromboses, necessitating treatment with edoxaban, aspirin, and hydroxyurea. Following thrombosis resolution, he was transferred to a transplantation center. This report delves into the thrombogenicity linked to the JAK2V617F mutation, while also examining documented instances of adrenal infarction in myeloid neoplasms. We should consider evaluating for JAK2V617F mutation even in cases of thrombosis at unusual sites, including adrenal infarction, even if there are no considerable abnormalities in blood counts.
