Chronic Generalized Lymphadenopathy in a Child-Progressive Transformation of Germinal Centers (PTGC).

BACKGROUND: Enlarged lymph nodes are a common complaint in a Pediatrician's office. Diagnosis of reactive lymphadenopathy secondary to infectious, inflammatory, immune dysregulation calls for clinical investigation, including a thorough history, physical exam, imaging, and less often, a biopsy of the lymph node. Here we discuss a rare presentation of extensive generalized, chronic, waxing, and waning lymphadenopathy diagnosed as Progressive Transformation of Germinal Centers (PTGC) and the course of illness over eight years follow up period.

DISCUSSION: Progressive Transformation of Germinal Centers (PTGC) is considered a benign condition, but extensive recurrent generalized lymphadenopathy in a very young child has not been reported before. This case demonstrates the importance of long-term follow-up and tailoring the diagnostic work-up and management based on new signs and symptoms. Here we focus on the clinical considerations and management of complex presentation of a common clinical finding.
