A case report of systemic lupus erythematosus combined with Castleman's disease and literature review

Delayed diagnosis of TAFRO syndrome: A case report

RATIONALE

TAFRO syndrome is a systemic inflammatory disorder, manifesting as thrombocytopenia (t), anasarca (a), fever (f), reticulin myelofibrosis/renal insufficiency (r), and organomegaly (o), and considered as a unique clinical subtype of idiopathic multicentric Castleman disease (iMCD). Such syndrome gave rise to a clinical picture similar to that of either a connective tissue disease or an autoimmune disease.

PATIENT CONCERNS

A Chinese young female initially presenting with arthralgia, Raynaud phenomenon, generalized edema, and a positive anti-small nuclear ribonucleoprotein particle antibody was diagnosed as mixed connective tissue disease. The kidney biopsy showed thrombotic microangiopathy. Bone marrow smear showed bone marrow hyperplasia and biopsy revealed suspected light chain restricted expression, megakaryocyte proliferation, and moderate to severe bone marrow fibrosis. A lymph node biopsy was conducted and the histopathological findings were consistent with the subtype of mixed Castleman disease. The clinical symptoms were relieved after regular chemotherapy.

DIAGNOSES

After above examination results and clinical manifestations, the final diagnoses was TAFRO syndrome.

INTERVENTION

The she was started on chemotherapy with bortezomib, cyclophosphamide, and dexamethasone.

OUTCOME

After chemotherapy, symptoms such as thrombocytopenia, hematuria and proteinuria disappeared, lymphadenopathy and VEGF level decreased, and bone marrow fibrosis relieved.

LESSONS

Our case illustrated the first cases of shared characteristics of mixed connective tissue disease and iMCD-TAFRO syndrome. Cytokines may play a role in the shared pathogenicity of the iMCD-TAFRO syndrome and systemic autoimmune diseases. Therapy directly against inflammatory factors such as corticosteroids or chemotherapy have an important therapeutic implication.

Systemic lupus erythematosus combined with Castleman disease and secondary paraneoplastic pemphigus: a case report

BACKGROUND

The literature describes a case of systemic lupus erythematosus (SLE) complicated with Castleman's disease (CD) and secondary paraneoplastic pemphigus (PNP).

CASE PRESENTATION

A 12-year-old female presented with a neck mass, rash, arthralgia, and skin and mouth ulceration for 5 years were admitted. All blood cells were low. Multiple autoantibodies associated with SLE were positive. The pathology of the neck mass revealed the classical manifestations of CD. She was treated with prednisone, hydroxychloroquine, leflunomide, thalidomide, and dressings. Pathological examination of the skin revealed PNP. The neck mass was removed and continued to take antirheumatic drugs. At subsequent follow-up, the patient's disease status was stable and the skin mucosal lesion did not recur.

CONCLUSION

The case of simultaneous SLE, CD, and PNP in children was rarely reported, and the correct diagnosis of the disease will help to take timely treatment.

Castleman disease presenting as lymphadenopathy in a female with systemic lupus erythematosus: A rare case report

Castleman disease is an infrequent disease that affects the lymph nodes and related tissues. The condition may manifest with lymphadenopathy, characterized by the enlargement of the lymph nodes, alongside additional symptoms such as high fever, nocturnal sweating, exhaustion, and loss of body mass. The diagnosis of Castleman disease typically entails a multifaceted approach that includes a physical examination, imaging modalities, and a biopsy of the lymph nodes that are affected. The selection of treatment modalities is contingent upon the classification and extent of the disease. Systemic lupus erythematosus (SLE) has been identified as a potential risk factor for the development of lymphoma, a condition that may manifest with lymphadenopathy resembling Castleman disease. Hence, it is crucial for individuals diagnosed with SLE and exhibiting lymphadenopathy to undergo a comprehensive assessment to exclude the possibility of any other associated disease. Although lymphadenopathy is a common symptom shared by both Castleman illness and SLE, these diseases have distinct etiologies and are treated in different ways. Seeking advice from a healthcare practitioner is crucial in order to obtain an accurate diagnosis and effective treatment. A 39-year-old female patient with a history of SLE since 18 years ago and lupus nephritis since 6 years ago which treated with Mycophenolic Acid 2 g daily, Hydroxychloroquine 400 mg daily, and low doses of Prednisolone. Also, Mycophenolic Acid has discontinued for her 5 months ago due to the reduction of proteinuria and the control of the disease. Although the association of Castleman Disease with SLE is infrequent, establishing a connection between them could prove advantageous in the treatment and etiology of diseases.

[Castleman-like presentation of systemic lupus: About a case report]

INTRODUCTION

Castleman disease is a rare lymphoproliferation, which may mimic systemic lupus. Conversely, systemic lupus sometimes presents like an hematological malignancy. In these cases, a "Castleman-like" histology has been exceptionally described.

OBSERVATION

A 55-year-old female treated by methotrexate for systemic lupus with skin and joint involvement presented weight loss, polyadenopathy and clinical signs of lupus flare. Biology showed pancytopenia, complement activation, and positive anti-DNA antibodies. PET/CT showed hypermetabolic polyadenopathy. The lymph node biopsy showed "Castleman-like" features. Treatment with corticosteroids and azathioprine resulted in complete remission.

CONCLUSION

Systemic lupus and Castleman disease may share common clinical, biological, and histological features. The presence of specific elements of systemic lupus flare and the remission obtained by low-dose corticosteroids results in considering the diagnosis of Castleman-like systemic lupus and avoiding treatment intensification.

Mimic or coincidentally? TAFRO syndrome and systemic lupus erythematosus: A case-based review

Castleman's disease (CD) is a rare, systemic disease with histopathological features of angiofollicular lymph node hyperplasia. In the literature, there are case-level reports that mimic or coexist with systemic lupus erythematosus (SLE) clinically and in the laboratory. Is this condition two separate diseases or is it an imitation of each other? A 73-year-old female patient was admitted to our clinic with arthritis, lymphadenopathy, fever, weight loss, and malar rash. He had a history of idiopathic thrombocytopenic purpura and thrombosis in the right leg tibialis posterior and dorsalis pedis arteries. Excisional lymphadenopathy biopsy indicated a diagnosis of hyaline-vascular-type CD. She had anti-nuclear antibody >1/80 homogeneous pattern, anti-double stranded DNA (anti-dsDNA), Anti-Smith (Sm) antibody positivity, hypocomplementemia (C3 and C4), pleural effusion, and pericardial effusion. For this reason, the classification criteria of the European League Against Rheumatism/American College of Rheumatology were studied. Clinical findings, idiopathic thrombocytopenic purpura history, antibody positivity, malar rash, and arthritis led us to the diagnosis of SLE. She was treated with 1 mg/kg/day prednisolone and hydroxychloroquine 200 mg 2 × 1. Azathioprine 2.5 mg/kg daily was added to the patient whose complaints did not improve. In the follow-ups, she completely recovered clinically and laboratory. SLE and CD are systemic diseases that overlap in many ways. The literature review shows that these two diseases may mimic each other or may coexist. This situation may be a reflection of a pathophysiological process that has not yet been clarified. This confusing process also affects the treatment decision. This confusing process also affects the treatment decision.

Diagnostics différentiels de la maladie de Castleman

Clinicians are sometimes confronted with the diagnostic difficulties of the idiopathic form of Castleman's Disease (iMCD). As this review reports with demonstrative clinical cases, iMCD can mimic various serious systemic pathologies such as certain autoimmune diseases, Still's disease, POEMS syndrome, and malignant lymphoproliferations, sharing a very similar histology and identical symptoms. To make a diagnosis of iMCD, the clinician must eliminate all the pathologies mentioned above, but he must first think of it and evoke this diagnosis of rare disease before the first symptoms but also know how to evoke this diagnosis again even after several years of evolution of a disease like those mentioned above whose evolution is not favorable. © 2022 Published by Elsevier Masson SAS on behalf of Société nationale française de médecine interne (SNFMI).

Castleman disease and SLE in a G6PD-deficient Marfan patient: a case report and literature review

Introduction

Marfan syndrome, G6PD deficiency, systemic lupus erythematosus (SLE), and Castleman disease are four distinctive, thoroughly investigated entities whose coincidence was never reported. However, occurrence in pairs was sporadically mentioned in literature.

Case presentation

We report a 15-year-old Caucasian G6PD deficient Marfan male patient, who presented with tonic–clonic seizures, fever, a hemolytic episode, and general symptoms. After the discovery of hepatosplenomegaly, malar rash, and painless lymphadenopathy, further testing diagnosed a multifocal Castleman disease of the hyaline vascular subtype and systemic lupus erythematosus with lupus nephritis that got 35 points on the 2019 EULAR/ACR criteria. G6PD deficiency, SLE & Castleman disease, and seizures were handled medically with eventual improvement in the patient’s condition.

Discussion and conclusion

It is extremely rare to discover the gathering of these four diseases in the same patient. Marfan syndrome and G6PD deficiency were proven by respective clinical and laboratory examinations. Castleman disease that tends to occur in older age groups was confirmed via pathological study of a lymph node biopsy, which was compatible with the HHV-8 negative type reported in Asian countries. SLE is part of the differential diagnosis for Castleman disease, yet the newest evidence strongly supports its presence as a distinct entity. However, no concrete proof is available to suggest a causative relationship between the four of them, rather than a coincidental occurrence.

Systemic lupus erythematosus complicated with Castleman disease: a case-based review

Systemic lupus erythematosus (SLE) is a complex, chronic, multi-systemic autoimmune disease, characterized by miscellaneous clinical findings. Castleman disease (CD) is a rare lymphoproliferative disorder that may present with systemic symptoms. Herein, a SLE case complicated with CD is reported by comparing her clinical findings with previously reported patients. We reviewed the literature regarding cases of "Castleman disease" and "Systemic lupus erythematosus" by searching medical journal databases in MEDLINE, EMBASE, Scopus, and Web of Science. A case of a 16-year-old girl with SLE who had intraabdominal lymphadenopathy detected both by ultrasonography and abdominal magnetic resonance imaging is presented. The excision of the lymph node was performed by pediatric surgeons. Histopathological examination was compatible with CD. Hydroxychloroquine and steroid treatments were started after the operation. She achieved remission in 3 months. In the literature research, we found 10 articles describing 17 patients. To our best of knowledge, the presented case was the third pediatric case in the literature with SLE and coexistent CD. This case report and literature review suggests that CD should be considered while evaluating and following patients with autoimmune diseases.

Characterization of patients with systemic lupus erythematosus who meet the diagnostic criteria for TAFRO syndrome

Purpose

TAFRO syndrome is a novel disorder manifesting as fever, anasarca, thrombocytopenia, renal insufficiency and organomegaly, and its etiology has not been clarified. The aim of this study was to elucidate similarities and differences between systemic lupus erythematosus (SLE) and TAFRO syndrome.

Methods

We examined 46 consecutive patients diagnosed with SLE and determined whether they meet the proposed diagnostic criteria for TAFRO syndrome (2015 version).

Results

Of the 46 patients with SLE, four (8.7%) also met the TAFRO syndrome criteria (TAFRO-like group). All patients in the TAFRO-like group were males, and their mean age was significantly higher than that of the non-TAFRO group (67.5 ± 8.7 vs. 39.3 ± 18.1 years, p = 0.004). C-reactive protein and γ-glutamyl transpeptidase levels were significantly higher, and frequencies of anti-dsDNA and anti-Sm antibodies were significantly lower in the TAFRO-like than non-TAFRO group. Elder cases (onset age ≥ 50 years) met significantly more categories of the diagnostic criteria for TAFRO syndrome than did those with younger cases.

Conclusions

Several patients with SLE, especially elder cases, showed features similar to those of TAFRO syndrome. Although exclusion of SLE is needed in the diagnostic criteria for TAFRO syndrome, TAFRO syndrome-like SLE should be considered.
