Morphological characteristics of the renal lesion in TAFRO syndrome and POEMS syndrome: a retrospective and multicenter study.

Clear kidney biopsy patterns now help doctors recognize and diagnose two ultra-rare plasma cell disorders earlier and more reliably.

This retrospective multicenter Japanese study characterizes renal histopathology in TAFRO and POEMS syndromes, two ultra-rare plasma cell disorders with poorly understood systemic manifestations. The findings establish morphological diagnostic criteria that can guide renal biopsy interpretation and improve early diagnosis of these challenging conditions.
