摘　　要：Primary pulmonary leiomyosarcoma （LMS） is a very unusual tumor.Although LMS has well-known metastatic potential,cutaneous metastasis is a remarkably uncommon.Exposure to cytotoxic agents could lead to ＂therapy-related myeloid neoplasm＂ （t-MN）.Starting from 2008,the World Health Organization （WHO） has adopted the term to cover the spectrum of malignant diseases previously known as therapy-related acute myeloid leukemia （t-AML）,therapy-related myelodysplastic syndrome （t-MDS） and therapy-related myelodysplastic/myelo-proliferative neoplasm （t-MDS/MPN）.We described the onset of t-MDS and progression to t-AML in one case diagnosed as primary pulmonary LMS with cutaneous metastasis.This patient achieved complete remission （CR） after three courses of IA regimen chemotherapy （idarubicin 5 mg/d,d 1-3;cytarabine 100 mg/d,d 1-5） and 1 course of HA chemotherapy regimen （homoharringtonine 3 mg/d,d 1-3;cytarabine 100 mg/d,d 1-7）.This case presents the natural course of therapy-related neoplasm and provides therapeutic experience for t-AML.Primary pulmonary leiomyosarcoma （LMS） is a very unusual tumor.Although LMS has well-known metastatic potential,cutaneous metastasis is a remarkably uncommon.Exposure to cytotoxic agents could lead to ＂therapy-related myeloid neoplasm＂ （t-MN）.Starting from 2008,the World Health Organization （WHO） has adopted the term to cover the spectrum of malignant diseases previously known as therapy-related acute myeloid leukemia （t-AML）,therapy-related myelodysplastic syndrome （t-MDS） and therapy-related myelodysplastic/myelo-proliferative neoplasm （t-MDS/MPN）.We described the onset of t-MDS and progression to t-AML in one case diagnosed as primary pulmonary LMS with cutaneous metastasis.This patient achieved complete remission （CR） after three courses of IA regimen chemotherapy （idarubicin 5 mg/d,d 1-3;cytarabine 100 mg/d,d 1-5） and 1 course of HA chemotherapy regimen （homoharringtonine 3 mg/d,d 1-3;cytarabine 100 mg/d,d 1-7）.This case presents the natural course of therapy-related neoplasm and provides therapeutic experience for t-AML.
