Cervical angiofollicular lymph node hyperplasia.

A three-and-a-half-year-old male with cervical angiofollicular lymph node hyperplasia is presented. Only 185 cases of this lesion have ever been described. The greater majority of these (80%) were located in the mediastinum. This case represents the youngest patient ever described as having such a lesion, especially located in the neck. The history, etiological theories, and pathology of this problem are discussed.
