Granulomatous Panniculitis as an Initial Manifestation of Sjögren Syndrome.

ABSTRACT

ABSTRACT A 65-year-old woman presented with unexplained weight loss, recurrent fever, and a dermatosis with painful nodules on the extremities. Biopsies showed focal lobular panniculitis with neutrophilic microgranulomas. Comprehensive investigations ruled out infection and hematologic and solid organ neoplasms. Laboratory results showed anti-Ro/SSA and anti-La/SSB antibody positivity, and elevated inflammatory markers. Dry mouth and eye were confirmed. The diagnosis of Sjögren syndrome with cutaneous panniculitis was established. Prednisone treatment with 30 mg/d resulted in remission of fever and pain improvement. This case emphasizes Sjögren syndrome as an autoimmune disease with multiple cutaneous manifestations and highlights its association with granulomatous panniculitis.
