RAAD-SARABIA, María et al. Cervical lymphadenopathy as an initial manifestation of systemic lupus erythematosus: about a clinical case. Rev. parag. reumatol. [online]. 2023, vol.9, n.2, pp.76-80.  Epub 30-Dic-2023. ISSN 2413-4341.  https://doi.org/10.18004/rpr/2023.09.02.76.

The presence of generalized lymphadenopathy has usually been associated with systemic lupus erythematosus (SLE), however, it is not usual to find this finding as an initial manifestation of the disease. There are multiple differential diagnoses that include Kikuchi histiocytic necrotizing lymphadenitis, Castleman disease, infections and lymphoma when this finding is presented as an initial symptom of SLE. We present the case of a 56-year-old man who presented with 2 months of generalized lymphadenopathy without examination findings or history suggesting a diagnosis of SLE; Lymphoma or infectious disease was initially suspected and an exhaustive study was performed, including cervical lymph node biopsy. Laboratory investigation finally revealed leukopenia, significant proteinuria, positive ANA, positive anti-dsDNA, and hypocomplementemia, confirming the diagnosis of SLE-type autoimmune disease. This case illustrates the importance of recognizing this unusual presentation, given that it is a potentially fatal disease.

Palabras clave : adenopathy; systemic lupus erythematosus; lymphoma.
