Subacute cutaneous lupus erythematosus presenting with generalized poikiloderma

The Spectrum of Cutaneous Manifestations in Lupus Erythematosus: A Comprehensive Review

Lupus erythematosus (LE) is an autoimmune inflammatory disease with complex etiology. LE may present as a systemic disorder affecting multiple organs or be limited solely to the skin. Cutaneous LE (CLE) manifests with a wide range of skin lesions divided into acute, subacute and chronic subtypes. Despite classic forms of CLE, such as malar rash or discoid LE, little-known variants may occur, for instance hypertrophic LE, chilblain LE and lupus panniculitis. There are also numerous non-specific manifestations including vascular abnormalities, alopecia, pigmentation and nail abnormalities or rheumatoid nodules. Particular cutaneous manifestations correlate with disease activity and thus have great diagnostic value. However, diversity of the clinical picture and resemblance to certain entities delay making an accurate diagnosis The aim of this review is to discuss the variety of cutaneous manifestations and indicate the clinical features of particular CLE types which facilitate differential diagnosis with other dermatoses. Although in diagnostically difficult cases histopathological examination plays a key role in the differential diagnosis of LE, quick and accurate diagnosis ensures adequate therapy implementation and high quality of life for patients. Cooperation between physicians of various specialties is therefore crucial in the management of patients with uncommon and photosensitive skin lesions.

Case Report: Rowell Syndrome-Like Flare of Cutaneous Lupus Erythematosus Following COVID-19 Infection

The current COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had an important impact on dermatology practice, posing diagnostic and therapeutic challenges especially in patients with inflammatory and autoimmune skin disorders. Disease-specific and nonspecific cutaneous manifestations have been increasingly reported in the spectrum of COVID-19 but the influence of the infection on pre-existing dermatologic diseases has not been clearly defined. There has been a debate in the literature as to whether patients suffering from autoimmune dermatoses, including cutaneous lupus erythematosus (CLE), are at increased risk of SARS-CoV-2 infection, as well as if they experience worsening of their lupus erythematosus (LE)-related clinical symptoms. This article reports on a case of Rowell syndrome occurring after COVID-19 in a 67-year old woman with pre-existing chronic CLE manifesting with few discoid lesions on the face, scalp, and upper chest, successfully controlled with topical corticosteroids and photoprotection. Erythema multiforme (EM)-like eruption developed approximately two weeks after the SARS-CoV-2 infection, the latter being confirmed by positive nasopharyngeal swab and successfully treated with systemic antibiotics and antiaggregants. Diffuse hair loss and patches of cicatricial alopecia were also present upon scalp examination. Laboratory workup, including routine tests, histologic, immunofluorescent, and serologic investigations, was supportive to the diagnosis. Administration of topical and systemic corticosteroids along with peroral hydroxychloroquine resulted in the progressive improvement of the cutaneous lesions. Rowell syndrome is a rare entity in the spectrum of LE, characterized by EM-like lesions, photosensitivity, and positive antinuclear and anti-Ro antibodies, that is currently considered to be a variant of subacute CLE (SCLE). Several cases of SCLE have been described in association with medications, including anti-SARS-CoV-2 vaccines but only a few reports incriminate the infection itself as a potential exacerbating factor. Based on the clinical course of the disease, we suggest that the observed Rowell syndrome-like flare of CLE was related to the COVID-19 infection in this 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.

Subacute cutaneous lupus erythematosus presenting as erythroderma

Erythrodema secondary to subacute cutaneous lupus erythematosus (SCLE) is rare. We report a 61-year-old man presenting with erythroderma secondary to SCLE. During erythrodermic phase our patient still had few annular and polycyclic lesions characteristic of SCLE. He was successfully treated with topical and oral corticosteriods.

Cutaneous lupus erythematosus: diagnosis and management

Cutaneous lupus erythematosus (CLE) includes a variety of lupus erythematosus (LE)-specific skin lesions that are subdivided into three categories - chronic CLE (CCLE), subacute CLE (SCLE) and acute CLE (ACLE) - based on clinical morphology, average duration of skin lesions and routine histopathologic examination. This paper describes our personal experience in the management of CLE over the last 30 years, with details on preferential therapeutic options related to clinical, histologic and immunopathologic aspects of each clinical subset of the disease. Effective sunscreening and sun protection are considered the first rule in the management of CLE because of the high degree of photosensitivity of the disease. Antimalarial agents are crucial in the treatment of CLE and are the first-line systemic agents, particularly in discoid LE (DLE) and SCLE. Dapsone is the drug of choice for bullous systemic LE (BSLE) as well as for LE in small dermal vessels (e.g. leukocytoclastic vasculitis). Retinoids, known as second-line drugs for systemic therapy, are sometimes used to treat chronic forms of CLE and are particularly successful in treating hypertrophic LE. Systemic immunosuppressive agents are required to manage the underlying systemic LE disease activity in patients with ACLE. These drugs, especially azathioprine, methotrexate, cyclophosphamide and cyclosporine, together with corticosteroids, constitute third-line systemic therapy of CLE. In our experience, oral prednisone or parenteral 'pulsed' methylprednisolone are useful in exacerbations of disease activity. Thalidomide provides one of the most useful therapeutic alternatives for chronic refractory DLE, although its distribution is limited to a few countries because of the risk of teratogenicity and polyneuropathy. However, medical treatment with local corticosteroids remains the mainstay of CLE treatment, especially for DLE. Patient education regarding the disease is also important in the management of CLE, because it helps relieve undue anxiety and to recruit the patient as an active participant in the treatment regimen.

Severe subacute cutaneous lupus erythematosus presenting with generalized erythroderma and bullae

A 31-year-old woman presented with progressive generalized erythroderma and bullae. Histologic evaluation revealed dyskeratosis and interface dermatitis with a paucity of infiltrate. Serologic evaluation revealed markedly elevated titer of Ro/SS-A and La/SS-B antibodies. Further workup revealed leukopenia. The generalized eruption cleared with prednisone. The patient later had the classic discrete lesions of subacute cutaneous lupus erythematosus develop. The erythrodermic and bullous presentation of subacute cutaneous lupus erythematosus is rare and requires a high index of suspicion.

Cutaneous lupus erythematosus: a review

This article will review and update information about the pathogenesis, clinical presentation, diagnosis, and treatment of cutaneous lupus erythematosus. Lupus erythematosus (LE) can present as a skin eruption, with or without systemic disease. Cutaneous LE is subdivided into chronic cutaneous LE, subacute cutaneous LE and acute LE. The prevalence of systemic lupus erythematosus (SLE) is 17-48/100,000 population worldwide. Skin disease is one of the most frequent clinical complaints of patients suffering from SLE. It has been found to occur in up to 70% of patients during the course of the disease. The most frequent mucocutaneous manifestations of SLE are malar rash (40%), alopecia (24%), and oral ulcers (19%). It has been suggested that risk factors that are more likely to signal transition of cutaneous into systemic LE are high ANA titers (> 1:320) and the presence of arthralgias. CLE patients who exhibit these symptoms should be monitored closely, since they may be at increased risk to develop SLE.

Treatment of poikiloderma of Civatte on the neck with an intense pulsed light source

Effective treatment of poikiloderma of Civatte is difficult. The ideal treatment combines elimination of both the vascular and pigmented components simultaneously. Treatment with a broad-spectrum noncoherent intense pulsed light source delivers multiple wavelengths with software-controlled pulse durations and sequencing that permit treatment of both vascular and pigmented lesions simultaneously. The objective of this study was to determine the response and side effects of treating this condition with intense pulsed light. In the study, 66 patients with typical changes of poikiloderma of Civatte on the neck were treated with intense pulsed light at various settings every 4 weeks until the desired improvement occurred. A 50 to 75 percent improvement in the extent of telangiectasias and hyperpigmentation was observed after an average of 2.8 treatments. The incidence of hypopigmentation was 5 percent. It was concluded that intense pulsed light is an effective mode of therapy for poikiloderma of Civatte. It seems to offer a reduction in both pigmentation and telangiectasia-associated erythema, with minimal side effects.

The cutaneous pathology of lupus erythematosus: a review

The presentation of lupus erythematosus (LE) ranges from a skin rash unaccompanied by extracutaneous stigmata to a rapidly progressive lethal multiorgan disease. The diagnosis and subclassification is traditionally based on the correlation of serological and clinical findings. The latter include a photoinduced skin rash, arthralgia, arthritis, fever, Raynaud's phenomenon, anemia, leukopenia, serositis, nephritis and central nervous sysdtem disease. The conventional classification scheme includes systemic, subacute cutaneous and discoid LE. Recent advances in our understanding of the cutaneous histopathology which correlates with the traditional forms of LE, along with certain novel LE subtypes, are the focus of this review. In addition to the main subtypes of LE, we will discuss associated vasculopathic lesions and the contribution of immunofluorescence microscopy to the diagnosis of LE and related connective tissue disease syndromes. Consideration will be given to unusual variants of LE such as anti-Ro/SSA-positive systemic lupus erythematosus (SLE), bullous SLE, lymphomatoid LE, lupus erythematosus profundus, drug induced LE, linear cutaneous LE, chiblains LE and parvovirus B19-associated LE.

Treatment of poikiloderma of Civatte with an intense pulsed light source

BACKGROUND

Effective treatment of poikiloderma of Civatte combines elimination of both the vascular and pigmented components simultaneously. A broad spectrum, noncoherent, intense pulsed light (IPL) source delivers multiple wavelengths with software controlled pulse durations and sequencing, which permits treatment of both vascular and pigmented lesions simultaneously.

OBJECTIVE

To determine response and side effects of poikiloderma of Civatte of the neck and chest when treated by IPL.

METHODS

One hundred and thirty-five patients randomly selected with typical changes of poikiloderma of Civatte on the neck and/or upper chest were treated with one to five treatments using IPL.

RESULTS

Clearance of more than 75% of telangiectasias and hyperpigmentation comprising poikiloderma was observed. The incidence of side effects was 5%, including pigment changes. In many cases, improved skin texture was noted both by physician and patient.

CONCLUSION

IPL is an effective mode of therapy for poikiloderma of Civatte. It offers a reduction of pigment and telangiectasias with a low risk profile. Additional benefits include subjective changes of improvement in skin texture.
