Lymphadenopathy in a series of Egyptian pediatric patients and the role of pathology in the diagnostic workup.

Assessment of lymphadenopathy in children represents a diagnostic challenge because of the extensive differential diagnoses, including reactive and malignant conditions. Knowledge of the etiologic pattern of lymphadenopathy in a given geographical region is essential for making a confident diagnosis or for suspecting a disease. Hence, the present study was carried out to identify different etiologies of lymphadenopathy in children in our region and to assess parameters commonly associated with malignancy, with an emphasis on the role of pathology.
