Self‐limiting sternal tumors of childhood (SELSTOC) are rare, self-limiting, dumbbell-shaped chest wall tumor found in young children.
Epidemiology
Median age is 16 months (range 7-50 months).
Pathology
The pathology is not clearly defined, but often shows aspecific inflammation.
Radiographic features
Ultrasound
Dumbbell-shaped hypo-echoic and inhomogeneous lesion which is formed between the sternum. Often without apparent vascularization. There is no destruction of bony structures or invasion of muscles. The lesion is sharply demarcated.
Treatment and prognosis
Most disappear spontaneously between 1-6 months. Follow up is advised. If the lesion does not decline between 6-8 weeks, an alternative diagnosis should be considered.
