Lupus erythematosus with antiphospholipid syndrome and erythema multiforme-like lesions

Rowell's syndrome in an Indian male and review of the literature

Lupus erythematosus (LE) with erythema multiforme-like lesions with its characteristic serological picture had been described in 1963. We report a 33-year-old married male who presented with skin lesions of various morphology on different body parts since four months. The skin lesions ranged from lupus-specific tumid LE to Rowell's syndrome and discoid LE. Histopathology of skin biopsy from all representative sites showed different forms of lupus erythematosus. Antinuclear and anti-double-stranded DNA was positive; however, serology for anti-SSA and anti-SSB was negative. There were no symptoms specific for organ involvement. It is unusual to document various morphological types in a single patient of lupus erythematosus. We document this case as all forms of cutaneous LE including Rowell's syndrome were evident in a single male patient.

The last word on the so-called 'Rowell's syndrome'?

To date, 71 patients having the so-called 'Rowell's syndrome' (RS) have been reported in the literature. However, most of them did not show all the clinical and serological features first described by Rowell and co-workers in 1963. Moreover, since then, subacute cutaneous lupus erythematosus (SCLE) has been identified and the diagnostic criteria as well as the clinical features of erythema multiforme (EM) defined. Accordingly several authors have questioned the existence of RS over the past years. In the present paper, the main clinical, histopathological and immunopathological features of both SCLE and EM are described and all of the cases of RS reported in the literature are also reviewed in depth. A real association between discoid LE and EM was present only in a minority of cases and could be considered a mere coincidence. As for other associations, e.g. those between CLE and lichen planus or psoriasis, the coexistence of CLE and EM does not justify the framing of a separate syndrome as suggested by Rowell et al.

Drug-induced subacute cutaneous lupus erythematosus: evidence for differences from its idiopathic counterpart

BACKGROUND

Drug-induced subacute cutaneous lupus erythematosus (DI-SCLE) is a lupus variant with predominant skin involvement temporally related to drug exposure and resolving after drug discontinuation. It usually presents with annular polycyclic or papulosquamous eruptions on sun-exposed skin and shows serum anti-Ro/SSA antibodies.

OBJECTIVES

To address the question whether DI-SCLE differs significantly from idiopathic SCLE by virtue of clinical features.

METHODS

Ninety patients with SCLE seen in our departments from 2001 to 2010 were reviewed. Eleven of them diagnosed as having DI-SCLE were evaluated for type of skin lesions, systemic involvement, clinical course, and histopathological, direct immunofluorescence and laboratory findings. The cutaneous features were compared with those of the 79 patients with idiopathic SCLE.

RESULTS

The cutaneous picture was widespread in 82% of patients with DI-SCLE and in 6% of those with idiopathic SCLE [odds ratio (OR) 66·6, 95% confidence interval (CI) 11·2-394·9; P = 0·0001]. Bullous and erythema multiforme (EM)-like lesions were present in 45% of patients with DI-SCLE and in 1% of those with idiopathic SCLE (OR 65·0, 95% CI 6·5-649·6; P = 0·0001). Vasculitic lesions were observed in 45% of patients with DI-SCLE and in 3% of those with idiopathic SCLE (OR 32·1, 95% CI 5·1-201·7; P = 0·0001). Malar rash occurred in 45% of patients with DI-SCLE and in 6% of those with idiopathic SCLE (OR 12·3, 95% CI 2·8-54·9; P = 0·001). Visceral manifestations were excluded in all patients with DI-SCLE. Anti-Ro/SSA antibodies were found in all but one patient with DI-SCLE and disappeared after resolution in 73% of cases.

CONCLUSIONS

DI-SCLE differs from idiopathic SCLE by virtue of distinctive cutaneous features, particularly the widespread presentation and the frequent occurrence of malar rash and bullous, EM-like and vasculitic manifestations.

Drug-induced lupus: an update on its dermatologic aspects

Drug-induced lupus erythematosus (DILE) is defined as an entity characterized by clinical manifestations and immunopathological serum findings similar to those of idiopathic lupus but which is temporally related to continuous drug exposure and resolves after discontinuation of the offending drug. Similar to idiopathic lupus, DILE can be divided into systemic lupus erythematosus (SLE), subacute cutaneous lupus erythematosus (SCLE) and chronic cutaneous lupus erythematosus (CCLE). Based on the literature review and retrospective analysis of our case series, we focused on the dermatological aspects of DILE. The cutaneous features of drug-induced SLE are protean, including particularly purpura, erythema nodosum and photosensitivity as well as the skin lesions characterizing both urticarial and necrotizing vasculitis. The typical laboratory profile of systemic DILE consists of positive antinuclear antibodies (ANA) and antihistone antibodies, the latter being regarded as the serum marker of this subset. The drugs most frequently implicated in the development of systemic DILE are hydralazine, procainamide, isoniazid and minocycline. Drug-induced SCLE usually presents with annular polycyclic or papulosquamous cutaneous manifestations as in the idiopathic form, but blisters or targetoid lesions mimicking erythema multiforme cannot rarely be associated. The clinical presentation is often generalized, with involvement of the lower legs that are usually spared in idiopathic SCLE. ANA and anti-Ro/SSA antibodies are usually present, whereas antihistone antibodies are uncommonly found. Drugs associated with SCLE include particularly calcium channel blockers, angiotensin-converting enzyme inhibitors, thiazide diuretics, terbinafine and the recently reported tumour necrosis factor (TNF)-α antagonists. Drug-induced CCLE is very rarely described in the literature and usually refers to fluorouracile agents or TNF-α antagonists. The picture is characterized by the occurrence of classic discoid lesions, but aspects of lupus tumidus can occasionally develop. ANA are demonstrated in around two-thirds of the cases. Management of DILE is based on the withdrawal of the offending drug. Topical and/or systemic corticosteroids and other immunosuppressive agents should be reserved for resistant cases.

Leflunomide-induced subacute cutaneous lupus erythematosus with erythema multiforme-like lesions

Leflunomide is an immunosuppressive agent that acts by inhibiting pyrimidine synthesis in lymphocytes and other rapidly proliferating cells, as well as by suppressing tumor necrosis factor-α–induced cellular responses. A number of leflunomide-related adverse events have been reported. Among cutaneous side effects, a few cases of subacute cutaneous lupus erythematosus have been described. We report a previously undocumented reaction to leflunomide, manifesting as subacute cutaneous lupus erythematosus and erythema multiforme-like lesions, in a young woman treated with this drug for ankylosing spondylitis. Withdrawal of leflunomide combined with a short cycle of systemic corticosteroid led to the resolution of the patient’s rash, indicating this drug as being responsible for the development of the disease. We conclude that leflunomide might have triggered the occurrence of both subacute cutaneous lupus erythematosus and erythema multiforme in a patient with pre-existing autoimmune diathesis. The suppressive effect of this drug on tumor necrosis factor-α–related mechanisms might have played a role in the induction of such a unique reaction to leflunomide.

[Rowell's syndrome or systemic lupus erythematosus and erythema multiforme. Association or coincidence?]

Rowell's syndrome is characterized by the association of systemic lupus erythematosus (SLE) and erythema multiforme-like lesions with the presence of immunological markers such as antinuclear antibodies with speckled pattern, anti-La antibodies and rheumatoid factor. We present the case of a 22-year-old woman with a diagnosis of SLE and erythema multiforme and discuss the possibility of distinguishing these entities from Rowell's syndrome.

Lupus erythematosus associated with erythema multiforme: report of two cases and review of the literature

Rowell's syndrome (RS) is a rare presentation of lupus erythematosus (LE) with erythema multiforme-like lesions associated with antinuclear, anti-La (SS-B)/anti-Ro (SS-A) antibodies and rheumatoid factor (RF) positivity. This syndrome is suggested to be a different variant of cutaneous lupus erythematosus by some authors in literature. Here we present a 64-year-old woman with LE and a 51-year-old woman with LE and Sjögren syndrome (SS) who had erythema multiforme-like eruptions and discuss the coexistence of lupus erythematosus and erythema multiforme.

Rowell's syndrome and associated antiphospholipid syndrome

We report a 27-year-old primigravida with systemic lupus erythematosus, erythema multiforme-like lesions and a peculiar immunological pattern consisting of antinuclear antibody (speckled pattern) and rheumatoid factor, an association known as Rowell's syndrome. She also had a probable antiphospholipid syndrome as evidenced by the presence of a prolonged activated partial thromboplastin time, kaolin clotting time and thrombocytopenia.

Differential diagnosis of severe cutaneous drug eruptions

Adverse cutaneous reactions to drugs are frequent, mostly secondary to antibacterials, however, serious adverse cutaneous reactions are infrequent. Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are a spectrum of the same disease. They are the more severe drug eruptions, with a mortality around 30% for TEN. The confusion between erythema multiforme major and SJS means that erythema multiforme major is the main differential diagnosis. Skin disorders involving desquamation, in particular after pustulosis, are also common differential diagnoses. Mechanical or autoimmune blistering are also potential misdiagnoses of TEN/SJS. Hypersensitivity Syndrome (HSS) or Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) is a severe cutaneous drug reaction with often a long duration of eruption and serious other organ involvement. Exfoliative dermatitis, whether caused by psoriasis, dermatitis or lymphoma, can be thought of as a differential diagnosis of DRESS/HSS. Angio-immunoblastic lymphadenopathy, viral eruption and vasculitis are other differential diagnoses of DRESS/HSS. Prompt recognition of a severe drug reaction and withdrawal of the culprit drug is often the most important therapeutic action. Alternatively, a delay in starting a specific treatment for a disease misdiagnosed as a drug eruption could be deleterious.
