Neck masses are common problems in infants and children. Some neck masses are congenital (present at birth) and result from abnormal formation during embryonic development. Many neck masses appear with an upper respiratory infection such as a cold or sinus infection. Some are not found until they become enlarged and painful from infection. Although a neck mass can involve other structures in the head and neck area, most are benign (non-cancerous). Cancerous neck masses are rare in young infants and children, but occasionally a mass is diagnosed as Hodgkin's or non-Hodgkin's disease - both cancers of the lymphatic system.
Further tests may be needed to completely diagnose the type of neck mass and whether other tissues and structures in the neck are involved. Treating neck masses depends on the type of mass and whether there is infection. Often, surgical removal of the mass is needed.
