Report of an Unusual Case: Testicular Involvement of Chronic Myeloid Leukemia 10 Years after the Complete Response

Abstract

Testicular extra-medullary myeloid cell tumours are rare tumours presenting in most cases with painless testicular swelling. We present here a case of 21-year-old man with painless scrotal swelling. From his medical history, he was treated by allogenic bone-marrow transplantation and chemotherapy 10 years ago because of chronic myeloid leukemia. The pathology of orchiectomy specimen revealed malign cells with blastic cell infiltration means a late relapse of chronic myeloid leukemia. The patient has been in hematological remission and no evidence of any myeloid disorders by 10 years’ follow up. Although testicular involvement is a rare and an unusual event in blast crisis of chronic myeloid leukemia, extramedullary myeloid cell tumour should be considered in the diagnosis of intratesticular tumours.
