Neck mass can be frequently encountered in pediatric patients. Most neck mass in pediatric patients are either inflammatory lesions or benign tumors but their differential diagnoses are not always easy. We must not forget the study results that a considerable portion of pediatric neck mass constitutes malignant tumors. Generally neck mass can be divided into inflammatory, developmental (congenital), and tumorous lesions. Developmental neck mass are generally thyroglossal duct cyst, branchial cleft cyst, dermoid cyst, vascular malformation, or hemangioma. Manifestations of inflammatory neck mass are reactive cervical lymphadenopathy, infectious lymphadenitis (viral or bacterial), mycobacterial cervical lymphadenopathy, or Kawasaki disease. The more uncommonly found pediatric malignant neck mass are lymphoma, rhabdomyosarcoma, or thyroid carcinoma. For the diagnosis of pediatric neck mass complete blood count, purified protein derivative test for tuberculosis, and measurement of titers for Epstein-Barr virus are required and in special cases, infectious diagnostic panels for cat-scratch disease, cytomegalovirus, human immunodeficiency virus, or toxoplasmosis may be needed. Ultrasonography is the most convenient and feasible diagnostic method in differentiating various neck mass. Computed tomography is performed when identifying the anatomical aspects of the neck mass or where deep neck infection or retropharyngeal abscess is suspected. Surgical management for congenital neck mass is recommended to prevent secondary infection or various complications following size increase. Most pediatric neck mass originate from bacterial lymphadenitis and antibacterial therapy is considered first line of conservative treatment. However if the neck mass is either over 2 cm in size without any evidence of inflammation, firm or fixed to surrounding tissue, accompanied by B symptoms, unresponsive to initial antibacterial therapy or over 4 weeks of conservative management, or considered keep growing for over 2 weeks, one must suspect the possibility of malignancy and must consult a head and neck specialist for further detailed evaluation.
