Kikuchi's disease (KD) can occur in association with systemic lupus erythematosus (SLE). The treatment of concomitant diseases, however, is unclear. We describe a case of a 45-y-old man who presented with generalized histiocytic necrotizing lymphadenitis, fever, malaise and weight loss. Ten months later he also developed arthritis, serositis, anemia, leukopenia and lymphopenia. ANA, anti-Smith, anti-snRNP and anti-Ro antibodies were positive. He responded rapidly and favorably to mid-dose prednisone. Hydroxychloroquine, added 5 months later, allowed tapering down and discontinuation of prednisone treatment. He has remained in complete remission for 5 years.

Systemic lupus erythematosus (SLE) is an immune complex disease with many different clinical presentations. Here we report a 13-year-old female patient presenting with generalized lymphadenopathy, who meanwhile developed butterflly rash and pericarditis. The diagnosis of SLE was based on the clinical features, positive antinuclear antibody, and positive antibodies to dsDNA. The patient had an active disease and developed renal involvement, despite steroid therapy. The patient's clinical presentation, course and response to therapy are detailed, and the literature on lupus lymphadenitis is reviewed.

The lymph node lesions of lupus lymphadenitis are characterized by necrosis sometimes accompanied by hematoxylin bodies, but only a few immunohistological analyses of this unique lesion have been reported. In this study we investigated the immunopathogenesis of these lesions. Lymph node specimens from four patients were analyzed immunohistochemically by applying recently developed monoclonal antibodies to immunocompetent cells. Necrosis occupied almost the entire lymph node in two cases (extensive type), whereas small foci of necrosis were found in the paracortex in the remaining two (localized type). No hematoxylin body formation was detected in any of the samples. Necrosis of the small muscular arteries, arterioles and venules was seen in the necrotic areas in all four cases. In one case of the localized type, necrotizing angitis was seen in a few arterioles and venules in the non-necrotic area. By immunohistology, amorphous depositions of immunoglobulins and C3 were demonstrated in the walls of the arterioles and venules in two cases. Our findings indicate that vasculitis due to local deposition of immune complexes in the blood vessels may play an important role in the pathogenesis of necrosis in lupus lymphadenitis.

In a young woman with clinical evidence of acute cutaneous, musculoskeletal, and neurologic manifestations of systemic lupus erythematosus, computed tomography (CT) showed enlarged, centrally hypoattenuating mesenteric and retroperitoneal lymph nodes. After treatment with steroids, the CT appearance of the lymph nodes returned to normal. The differential diagnosis of lymph nodes with central hypoattenuation includes Mycobacterium tuberculosis infection, metastatic disease (especially squamous cell carcinoma and germ cell tumor), Whipple's disease, and celiac disease in addition to lupus lymphadenitis.

Forty-five examples of Kikuchi's lymphadenitis (KL), 5 Kikuchi-like lupus erythematosus lymphadenopathies, 25 nonnecrotizing lymphadenitidies (5 toxoplasmic, 5 sarcoid-like, 6 dermatopathic, 4 suppurative, 3 tubercular, 2 with sinus histiocytosis), 4 examples of hyaline-vascular Castleman disease (CD), 2 plasmacytoid monocyte tumors (PM-Ts), and 61 accessory cell neoplasms were studied by a panel of antibodies, including the PG-M1 (against a macrophage-restricted CD68 epitope) and a polyclonal anti-myeloperoxidase (MPO). In KL and Kikuchi-like lupus erythematosus lymphadenopathies, 25 to 75% of CD68(+) histiocytes co-expressed MPO. This did not occur in nonnecrotizing lymphadenitidies and accessory cell neoplasms. MPO(+)/CD68(+) elements corresponded to nonphagocytosing mononuclear cells and some crescentic macrophages and phagocytosing histiocytes. Typical PMs were MPO(-)/CD68(+) in all cases, including CD and PM-T. Our observations suggest that in KL and KL-like lymphadenopathies: 1) MPO(+)/CD68(+) blood monocytes might be attracted into tissues because of the lack or paucity of granulocytes and the need of MPO for oxidative processes; 2) PMs are more likely to be involved in the cytotoxic immune reaction than in phagocytic phenomena; 3) the peculiar phenotype of the histiocytic component can be usefully used for the differentiation from malignant lymphoma and PM-T.

Kikuchi-Fujimoto's disease (KFD), Histiocytic Necrotizing lymphadenitis, is a rare self-limiting condition characterized by lymphadenopathy, fever and neutropenia. The aetiology of KFD is controversial, and its diagnosis is confirmed histologically. Although KFD has rarely been reported associated to Systemic lupus erythemotosus (SLE) should be ruled out given its different prognosis and management. We present the clinical, histological and evolution the two cases of patients with Kikuchi's disease; one case had evolution classic and the other case were associated with SLE.

Cyclosporin has been increasingly used for the treatment of skin diseases in small animals. Reported uses include the treatment of atopy, cutaneous lupus erythematosus, feline acquired alopecia resembling pseudopelade of humans, pemphigus erythematosus, pemphigus foliaceus, perianal fistulae and sebaceous adenitis. In addition, cyclosporin has been used anecdotally for several other skin diseases. Few side effects have been noted at doses therapeutic for dermatologic diseases. Current suggestions for monitoring, and the value of trough cyclosporin serum concentrations for prediction of toxicity and efficacy are discussed.

Kikuchi-Fujimoto disease (KFD) is a histiocytic necrotizing lymphadenitis found mainly in young women. Patients typically present with cervical lymphadenopathy and fever and follow almost always a benign course with excellent outcomes. The etiology of KFD remains unknown and controversial although several viruses have been associated with this disease. One theory proposes that KFD may be a self-limiting form of systemic lupus erythematosus (SLE). This theory is strongly supported by the fact that microscopic features of KFD can be very similar to those found in lupus lymphadenitis. Despite its usually benign course, several cases with fatal outcomes have been reported. We report here a case of clinically aggressive KFD, which featured several autoimmune-related events and resulted in a fatal outcome. Autopsy studies showed characteristic findings of SLE, which suggests a remarkable link between SLE and KFD. Early and intensive immunosuppressive treatment may be the only option for patients who develop very aggressive forms of KFD in order to avoid a fatal outcome.

Kikuchi's disease (KD) or Kikuchi's lymphadenitis (KL) is a self-limiting disease mostly affecting the cervical lymph nodes of young individuals. Whether the reported cases of KL associated with systemic lupus erythematosus (SLE) were genuine KL or lupus lymphadenitis (LL) simulating KL in SLE patients is not clear. We analyzed six cases of KD-like lymphadenitis occurring in SLE patients and 12 reported cases to clarify the relationship between KL and SLE. We found that not all cases occurred simultaneously with SLE. Eight cases occurred either before or after SLE. These cases might have true KL independent of SLE with the exception of two cases that occurred after SLE, but the patients still had lupus activity. The 10 cases that coexisted with SLE most likely had LL rather than KL. This was supported by the immunohistochemical finding of sparse cytotoxic T cells in those lymph nodes in contrast to abundant cytotoxic T cells usually seen in a typical KL. We conclude that KL is not related to SLE, and KD-like lymphadenitis coexisting with SLE should be regarded as LL. Pathologists should be aware of the possibility that LL can mimic KL in patients with SLE, especially necrotizing-type KL.

Necrotizing histiocytic lymphadenitis (NHL) or Kikuchi-Fujimoto disease is an infrequent seen clinicopathologic entity that affects most frequently young women and individuals of eastern races, and that is characterized by fever and adenopathies (basically cervical) and systemic disease even though occasional patients present extranodal disease. We present two young women with NHL and cutaneous affectation, and with lymphocytic meningitis in one of the patients. We discuss the etiology of NHL, the relation of NHL with collagen-vascular diseases (basically systemic erythematous lupus) the problem of the pathologic diagnosis, and the therapeutic possibilities in these patients.
