Secondary leukemias are usually forms of leukemias which are developed due to therapy administered for a previous malignancy. Radiotherapy or chemotherapy induced leukemia is a complication which follows treatment of a different primary malignancy. A case of acute monoblastic leukemia following treatment of the invasive carcinoma cervix (treated by radiotherapy and chemotherapy) is reported. This secondary leukemia developed one year after treatment. This case is being presented due to its rarity.
