Kimura Disease in Colombia. Case Report

Abstract

Introduction: Kimura disease is a benign, chronic, and rare entity. Its etiology and pathogenesis are unclear, posing challenges for diagnosis and management. The aim is to report the case of a Colombian patient with Kimura disease. Case Report: A 68-year-old male patient with no relevant medical history presented with a 6-month history of asthenia, night sweats, and bilateral cervical lymphadenopathy. An excisional lymph node biopsy was performed, revealing atypical paracortical hyperplasia with a Ki67 proliferation index of 60% in the paracortical region and 100% in residual germinal centers, suggesting a reactive process consistent with Kimura disease. Discussion: This case highlights the importance of considering Kimura disease as a differential diagnosis in patients with symptoms consistent with this condition.
