Excerpt

A 13-year-old boy presented to the authors’ institution with a 6-month history of a mass in his left calf. The mass had not decreased in size despite the patient’s use of cold compresses and compression bandages. The patient denied experiencing pain when walking or with knee flexion, although the mass was painful if accidentally bumped. The patient did not complain of fevers, chills, nausea, or vomiting. He otherwise was healthy and his medical and family history were unremarkable.
On physical examination, the patient was a healthy appearing, well-developed 13-year-old boy in no apparent distress. The patient had good motor strength and function in all extremities. A soft tissue mass, approximately 8 × 6 cm in diameter, was palpated along the proximal and lateral aspect of his left calf. There was no localized warmth, erythema, or tenderness. Peripheral pulses were intact bilaterally and neurologic examination was unremarkable. Left inguinal lymphadenopathy was present.
A radiograph of his left knee, taken at another hospital, revealed a soft tissue mass with osteolytic reaction of the proximal tibia (Fig 1). Magnetic resonance imaging scans of the lower extremities (Fig 2), a CT scan of the chest (not shown), a bone scan (Fig 3), and laboratory tests were ordered. Complete blood count, basic metabolic panel, calcium level, and CT scan of the chest were normal.
