Tonsillar Diffuse Large B-Cell Lymphoma of Non-Germinal Center Type With Cluster of Differentiation 5 Positive in a Pediatric Girl.

Lymphoma is a common malignancy in children. It is the second most common malignancy in children older than 1 year of age. Most extranodal non-Hodgkin lymphoma (NHL) in the head and neck is usually caused by diffuse large B-cell lymphoma (DLBCL), but pediatric DLBCL with cluster of differentiation (CD)5 expression is rarely discussed in the literature.
