RT Journal Article SR Electronic T1 B cell acute lymphoblastic leukaemia presenting with isolated soft tissue tumours: the non-myeloid sarcoma JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e230982 DO 10.1136/bcr-2019-230982 VO 12 IS 10 A1 Mohammad Tousifullah A1 Aditya Kumar Gupta A1 Jagdish Prasad Meena A1 Rachna Seth YR 2019 UL http://casereports.bmj.com/content/12/10/e230982.abstract AB Soft tissue leukaemic masses are a well-described clinical feature of myeloid haematological neoplasms. In paediatric acute lymphoblastic leukaemia (ALL), such soft tissue leukaemic sarcomas have not been reported as a presenting feature. Here we report a 3-year-old boy with ALL who presented to us with isolated soft tissue swellings for a duration of 9 months. The significance of these ‘non-myeloid’ sarcomas in paediatric ALL is uncertain.
