Neck masses: diagnostic analysis of 630 cases in Turkish population.

Neck masses can be classified into three main categories: congenital, inflammatory and neoplastic. Our aim was to determine the distribution of diagnosis in patients who were followed-up for a neck mass and had undergone surgery for diagnostic indications. Six hundred and thirty cases referred to the Otorhinolaryngology and Head Neck Surgery Department of Haseki Research and Training Hospital between January 2005 and February 2012 with a neck mass who underwent excisional or incisional biopsy to establish a histopathologic diagnosis were retrospectively evaluated. Patients with a diagnosis of upper aerodigestive tract malignancy were excluded from the study. As well as the patients with thyroid masses were excluded. Only unknown primary neck masses were included in the study. The neck masses were categorized as inflammatory (33.49 %), congenital (18.9 %) or neoplastic (47.6 %). Neoplastic masses were either benign (51 %) or malignant (49 %) tumors. The most common causes were tuberculous lymphadenitis (40.28 %) among inflammatory masses, thyroglossal duct cysts (32.77 %) among congenital masses, pleomorphic adenoma (22.33 %) among benign neoplastic masses, and lymphoma (20 %) among malignant neoplastic masses. The most common types of mass were congenital in the 0-20 year age group, benign neoplastic in 21-40-year-old and malignant neoplastic in the >40-year group. Any neck mass, especially in an elderly patient, should be managed with caution as a considerable proportion may be malignant. In children and adolescents, a neck mass requiring surgery is most likely to be congenital. Tuberculosis should be considered as a cause of a neck mass due to a long-term inflammatory process in a developing country.
