Acute Lymphoblastic Leukemia Presenting as Soft Tissue Mass
February 04, 2010
For 3 months, a 9-year-old boy had swelling of the left upper arm. An MRI scan obtained at another facility 1 week after onset showed extensive edema of the soft tissue at the midhumeral level. Laboratory results, including complete blood cell (CBC) count and Lyme titer, were normal.
