Аннотация
BACKGROUND: Progressive transformation of germinal centers (PTGC) is a rare diagnosis characterized by asymptomatic lymph node enlargement. It has previously been associated with lymphoma, autoimmune conditions, and lymphoproliferative diseases in small pediatric case series.
PROCEDURES: We conducted a single-center retrospective review of pediatric cases of PTGC diagnosed at our institution by hematopathologists from 2000 to 2020.
RESULTS: We identified 57 primary cases and three recurrent cases of PTGC. Laboratory and imaging evaluations were obtained inconsistently. Nine patients (16%) saw a pediatric hematology/oncology (PHO) specialist prior to diagnosis, and 21 (37%) had follow-up with PHO after diagnosis.
CONCLUSIONS: Patients with PTGC had similar age and involved lymph node sites to those from previous case series. Fewer patients underwent recurrent lymph node biopsy than previously described. PTGC has been linked to certain types of lymphoma, although never definitively associated with lymphoma. Follow-up with a PHO provider is indicated to ensure that close surveillance is performed.
