[Kikuchi-Fujimoto disease prior to childhood-systemic lupus erythematosus diagnosis].

Kikuchi-Fujimoto disease (KFD) is a self-limiting histiocytic necrotizing lymphadenitis of unknown origin. Of note, KFD was infrequently reported in adult systemic lupus erythematosus (SLE), with rare occurrence in childhood-SLE (C-SLE) patients. To our knowledge, the prevalence of KFD in the paediatric lupus population was not studied.

Fatal cryptococcal meningitis in a juvenile lupus erythematosus patient.

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans, generally associated with immunodeficiency and immunosuppressive agents, and it is rarely reported in systemic lupus erythematosus (SLE), particularly in juvenile SLE (JSLE). From January 1983 to June 2011, 5,604 patients were followed at our University Hospital and 283 (5%) of them met the American College of Rheumatology (ACR) classification criteria for SLE. Only one (0.

Mesenteric vasculitis in a juvenile systemic lupus erythematosus patient.

Lupus mesenteric vasculitis (LMV) is a rare cause of acute abdominal pain. Few cases of LMV have been reported in adults, children and adolescents. However, to our knowledge, the prevalence of that severe vasculitis in a pediatric population with lupus is yet to be studied.

Severe intestinal involvement as initial manifestation of systemic childhood polyarteritis nodosa: report of two cases.

Systemic childhood polyarteritis nodosa (C-PAN) is a rare primary vasculitis involving medium or small sized arteries. Abdominal angina is an important and serious complication of PAN, occurring usually 15 to 30 min after food intake, and particularly in adult patients. However, to our knowledge, this involvement as the first manifestation of C-PAN was not described.

Disseminated histoplasmosis in a juvenile lupus erythematosus patient.

Introduction: Histoplasmosis is an infection caused by dimorphic fungus, Histoplasma capsulatum, and it has not been reported in juvenile systemic lupus erythematosus (JSLE) patients, particularly progressive disseminated histoplasmosis (PDH) subtype.

Case Report: We reported herein a 14-year old girl who was diagnosed with JSLE. Six months later, she had abdominal distension and received prednisone, hydroxychloroquine and azathioprine.
