Testicular relapse in adult acute myelogenous leukemia.

Abstract

Testicular relapse (TR) in adult acute myelogenous leukemia (AML) is uncommon, occurring in only 1-2% of patients with bone marrow relapse. TR in the absence of systemic relapse has been reported previously in 2 adults and 12 children, of which 67% were monocytic variants of AML. This article presents the case of a 29-year-old man with AML that relapsed in his testicle without evidence of bone marrow relapse. This patient and the two previously mentioned adults experienced bone marrow relapse within 2 months and died within 7 months of their TR. TR in adult myelogenous leukemia should be considered a harbinger of systemic relapse and suggests a need for aggressive local and systemic therapy.
