Sweet's syndrome with panuveitis resembling Behçet's disease

Neutrophilic dermatosis and hidradenitis suppurativa in patients with Behçet's disease: A neutrophilic disease in the spectrum of autoinflammatory syndromes

BACKGROUND

Association of neutrophilic dermatosis (ND), hidradenitis suppurativa (HS) and Behçet's disease (BD) and shared efficacy of TNFα axis blockade suggests common physiopathology.

OBJECTIVES

To investigate the clinical features and therapeutic response of ND and HS associated with BD.

METHODS

We identified 20 patients with ND or HS associated with BD among 1462 patients with BD.

RESULTS

We analysed 20 (1.4%) patients diagnosed with ND or HS associated with BD: 13 HS, 6 pyoderma gangrenosum (PG), and 1 SAPHO. Our 6 PG cases over 1462 BD patients accounts for 400/100 000 prevalence. Thirteen had bipolar aphthosis, 6 vascular, 5 neurologic, and 4 ocular involvements. All PG occurred on limbs and had typical histology with constant dermal neutrophilic infiltrate. All HS had the classical axillary-mammary phenotype. Sixty-nine percent (69%) of HS were Hurley 1 stage. Treatment consisted mainly in colchicine (n = 20), glucocorticoids (n = 12), and anti-TNFα (n = 9). Interesting results with complete or partial responses were obtained with anti-TNFα (9 cases), ustekinumab (3 cases) and tocilizumab (1 case) to treat refractory ND or HS associated with BD.

CONCLUSION

PG seems overrepresented in patients with BD. Biotherapies such as anti-TNFα, ustekinumab and tocilizumab appear to be promising to treat refractory ND or HS associated with BD.

Panuveitis in Sweet syndrome

Ocular manifestations of Sweet syndrome, or acute febrile neutrophilic dermatosis, are usually limited to the anterior segment. We report the case of a patient with bilateral panuveitis and retinal vasculitis associated with Sweet syndrome. A 45-year-old Asian female with an undiagnosed febrile illness with rash presented with bilateral panuveitis with haemorrhagic occlusive retinal vasculitis. Skin biopsy confirmed Sweet Syndrome. Intraocular inflammation resolved with a combination of topical and systemic corticosteroids as well as intravenous cyclophosphamide, with resulting permanent severe right visual impairment. Although an uncommon condition, Sweet syndrome should be considered in any febrile patient with skin lesions and uveitis.

Relentlessly Progressive Sweet Syndrome of the Eye with Scleritis and Choroidal Infiltration

PURPOSE

To describe a case of Sweet syndrome, a dermatologic inflammatory disease, with progressive, unrelenting ocular findings.

METHODS

Case report.

RESULTS

A 73-year-old male was evaluated with a six-month history of Sweet syndrome, manifesting as cutaneous erythematous edematous papules on the dorsal arms and shins and confirmed with biopsy demonstrating neutrophil infiltration with nuclei fragmentation and lack of vasculitis. He initially noted a unilateral red eye with ocular pain and was found to have scleritis and choroidal infiltration. The patient's ocular disease progressed despite treatment with systemic corticosteroids, intraocular Ozurdex ®, systemic dapsone, and subtenons triamcinolone. Systemic evaluation was negative for malignancy or other inflammatory syndromes. Following 7 months of non-manageable ocular pain enucleation was offered to the patient, but he declined.

CONCLUSION

Sweet syndrome, a dermatologic condition, can be associated with unilateral scleritis and choroidal infiltration that are relentlessly progressive despite maximal systemic and ocular corticosteroid therapy.

A Case Report of Sweet's Syndrome with Panuveitis and Rhegmatogenous Retinal Detachment

Purpose: To report a case of a patient who suffered from Sweet's syndrome with panuveitis in both eyes.Materials & Methods: Retrospective interventional case report.Results: A 54-year-old Chinese male patient complained of fever, painful skin lesions and blurry vision in both eyes lasting for 4 days. His visual acuity was hand motion in both eyes. Slit-lamp examination showed the hypopyon and severe vitreous opacification in both eyes. A skin pathology from head skin lesion demonstrated diffuse neutrophilic infiltration in the dermis with karyorrhexis. Based on the inspection above, the patient was diagnosed with Sweet's syndrome and given systemic corticosteroids therapy. However, he developed secondary rhegmatogenous retinal detachment in the right eye during his treatment.Conclusion: The association of bilateral uveitis with Sweet's syndrome has been described in this report.

[Vasculitis mimics]

Vasculitis mimics need to be differentiated from primary and secondary vasculitides as described in the Chapel Hill nomenclature. The clinical symptomatology resembles that of vasculitis of small and medium, rarely also large vessels and hence imitates the classical vasculitic disorders. Pathogenetically, the causes are partly genetic mutations, embolization syndromes, infections and substance abuse. Also, B‑cell lymphomas can mimic vasculitis. The present manuscript summarizes the vasculitis mimics.

Neuro-Ophthalmic Presentation of Neuro-Sweet Disease

Acute febrile neutrophilic dermatosis (Sweet syndrome) is a systemic inflammatory condition usually associated with autoimmune or neoplastic processes and characterised by inflammatory dermatologic lesions such as erythematous plaques and papules associated with fever and leukocytosis. Neurological and ophthalmological involvement is rare. The authors describe an unusual case of Sweet syndrome associated with microscopic polyangiitis presenting with papilloedema, anterior uveitis, and skin rash. Years later, he developed acute posterior multifocal placoid pigment epitheliopathy. Treatment with immunosuppressive medications led to a relapsing remitting course with maximum benefit from use of steroids. The authors describe the difficulties in diagnosis and treatment of this rare case.

A Review and Proposed Approach to the Neutrophilic Dermatoses of Childhood

Neutrophilic dermatoses (NDs) are inflammatory skin conditions that are not associated with infection. The classification and clinical approach to these conditions in children is poorly described. This review classifies these conditions into five nosological subtypes: Sweet's syndrome, pyoderma gangrenosum, aseptic pustules, neutrophilic urticarial dermatoses, and Marshall's syndrome. In addition, we review the various secondary diseases that need to be excluded in the clinical management of the NDs of childhood, with a focus on the autoinflammatory conditions that the reader may not be familiar with. We propose a practical clinical approach to these disorders.
