Evaluation of palpable neck masses may be a diagnostic problem in pediatric patients, with differential diagnosis including congenital, inflammatory, tumoral and traumatic lesions. Ultrasonography is usually a satisfactory method to make a correct pre-operative evaluation of neck masses, although diagnosis is often challenging for the surgeon and the radiologist and sometimes only possible after a histopathological examination of the resected lesion.
We report an 8-month-old patient with a cervical, anterior midline mass. Ultrasonographic images showed features suggesting a partly cystic lesion, with a preoperative suspect of thyroglossal duct cyst. Histological examination, performed after surgical removal of the mass, led to a diagnosis of lymph node angiomyomatous hamartoma (AH).
AH, a rarely occurring benign lymph node lesion, has been reported in the neck lateral region only twice. This case, presenting as a palpable neck midline mass, is the first reported case occurring in infancy. Although rare, AH should be included in the differential diagnosis of head and neck masses.
