The authors report the occurrence of lichenoid and/or subacute lupus erythematosus-like eruptions in a group of patients receiving agents with antihistaminic properties. In 1 of the patients the eruption clinically resembled lichen planus, while in 5 patients the eruption resembled subacute cutaneous lupus erythematosus (SCLE). At a light microscopic level all cases showed a lichenoid dermatitis and in 4 cases the lesions were interpreted as representing subacute lupus-like eruptions by virtue of the presence of alternating cell poor and lichenoid interface dermatitis, suprabasilar lymphocytosis around degenerating keratinocytes, and dermal mucinosis. Despite the resemblance at a clinical and light microscopic level to SCLE, anti-Ro seropositivity could not be established in any of the cases. One case, however, did demonstrate antihistone antibodies in concert with a high antinuclear antibody titer. A causal association was implicated by virtue of lesional resolution following drug withdrawal. The association of cutaneous eruptions resembling SCLE with antihistamine intake is seemingly a novel one. The possible pathogenetic basis of the eruptions is discussed.

Various oral medications including nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with pseudoporphyria, although the pathogenetic basis has not been elucidated. A novel NSAID nabumetone (Relafen) has become popular because of its minimal gastrointestinal side effects. Its association with pseudoporphyria is not reported save for its listing in the Physician's Desk Reference (PDR) as a possible side effect. Biopsies of lesional skin from 4 patients manifesting blisters and erosions on the hands and face within 4 months of starting nabumetone were submitted for light microscopic and immunofluorescent (IF) studies. Histories and serology were obtained. Two patients had rheumatoid arthritis (RA), 1 had mixed connective tissue disease (MCTD), and 1 received diltiazem. All 4 had antinuclear antibodies. Characteristic clinical, light microscopic and IF features in the absence of elevated urine porphyrin levels confirmed a diagnosis of pseudoporphyria in all 4 patients. Biopsies in three patients showed features attributed to underlying connective tissue disease (CTD), including ectasia of the superficial vascular plexus, mild leukocytoclastic vasculitis, superficial and deep perivascular lymphocytic infiltrates with dermal mucinosis, granular deposition of IgM along the dermoepidermal junction indicative of a positive lupus band test, and of IgG and C5b-9 within keratinocytes. Nabumetone (Relafen) can provoke pseudoporphyria; an underlying CTD diathesis may be a predisposing factor.

Periorbital edema associated with lupus erythematosus is not frequently reported. To our knowledge, periorbital edema from increased dermal mucin has not been reported with any form of lupus. We present a patient with discoid lupus exhibiting periorbital edema from massive mucinosis.

We report the case of a woman with clinical and histopathological features of reticular erythematous mucinosis syndrome (REM) who six years later developed diagnostic criteria for systemic lupus erythematosus (SLE). Two biopsies performed at the same area initially showed mucin dermal deposits and further development of characteristic dermo-epidermal changes of lupus erythematosus. Our findings suggest that SLE may present with an REM-like condition.

The prototypical cutaneous manifestations of human parvovirus B19 (B19) infection include a petechial eruption in a glove and stocking distribution, reticular truncal erythema, and the "slapped cheek" sign. An association with connective tissue disease (CTD) stigmata has recently been made. The clinical and dermatopathologic findings in 14 patients whose skin lesions were accompanied by serological evidence of B19 infection or documentation of B19 genome in lesional skin are presented. The authors encountered skin biopsy specimens from 14 patients who presented with skin eruptions accompanied by clinical signs or serology suggestive of antecedent B19 infection. Clinical findings were correlated to the light microscopic appearance of the lesions and the presence of B19 genome in lesional skin. The study group comprised 9 women, 3 men, and 2 boys. Eruptions characteristic of fifth disease, including the slapped cheek sign, reticulated truncal erythema, and acral petechiae, were present in 3 patients, 1 of whom later developed granuloma annulare. The other patients had atypical clinical presentations comprising an asymptomatic papular eruption (2), an eruption clinically resembling Sweet's syndrome (3), myopathic dermatomyositis (DM) (2), lupus erythematosus (LE)-like syndromes (2), and lower-extremity palpable purpura (2). Skin biopsy specimens in 12 cases showed interstitial histiocytic infiltrates with piecemeal fragmentation of collagen and a mononuclear cell-predominant vascular injury pattern. Other features included an interface dermatitis, eczematous alterations, and papillary dermal edema. Lesions with features of DM or LE also showed mesenchymal mucinosis, whereas a biopsied lesion of palpable purpura showed leukocytoclastic vasculitis (LCV). Immunofluorescent testing showed a positive lupus band test (LBT) with epidermal IgG and C5b-9 decoration in 1 patient with a systemic LE-like illness, whereas the DM patients had negative LBTs and vascular C5b-9 deposition typical for DM. Skin biopsy specimens from 11 patients, including those whose presentations resembled LE and DM, were positive for B19 genome. The dermatopathology of B19 infection suggests tissue injury mediated by delayed-type hypersensitivity, by antibody-dependent cellular immunity directed at microbial antigenic targets in the epidermis and endothelium, and by circulating immune complexes in the setting of LCV. These mechanisms appear to generate a clinical and histopathological picture that recapitulates that of CTD.

Papular and nodular mucinosis is a distinct form of cutaneous mucinosis associated with systemic lupus erythematosis. We report a case in which papular and nodular mucinosis predated early findings of progressive systemic sclerosis.

Tumid lupus erythematosus (TLE) is a variant of cutaneous lupus erythematosus. Most patients who present with these skin lesions are young women. The condition clinically resembles polymorphous light eruption, systemic lupus erythematosus (SLE), reticulated erythematous mucinosis, or gyrate erythema. Histopathologically, the lesions resemble classic lupus erythematosus because of their superficial and deep lymphohistiocytic inflammatory infiltrates and dermal mucin. However, unlike classic lupus erythematosus, there is little or no epidermal or dermo-epidermal involvement. Antinuclear antibody test results are usually negative. We describe 4 cases of TLE and discuss the differential diagnosis.

The patient was a 44-year-old female. She was diagnosed as having systemic lupus erythematosus at the age of 21 years and had been receiving systemic steroid treatment (5 mg prednisolone/day). Nodules began to appear on her neck, chest and back from June in 2000, and she was referred to our clinic for examination and treatment. Examination of a biopsy sample of an eruption on the neck revealed mucin deposition in the dermis. Based on the clinical and histopathological findings, she was diagnosed as having typical nodular cutaneous lupus mucinosis. The dose of steroid was increased, and the eruptions gradually disappeared.

Lupus mucinosis (LM) is a rare disorder found only in patients with systemic lupus erythematosus (SLE) or discoid lupus erythematosus (DLE). We describe a patient with lupus mucinotic nodules as the initial presenting sign of SLE. We further discuss other forms of cutaneous lupus and contrast them with our findings.

A 41-year-old man with systemic and serological manifestations of systemic lupus erythematosus presented with a diffuse eruption comprising annular plaques. Histopathology revealed diffuse deposition of mucin throughout the dermis, consistent with papulonodular mucinosis. This uncommon entity of unclear pathogenesis has been described in systemic lupus erythematosus, discoid lupus erythematosus, and subacute cutaneous lupus erythematosus.
