We isolated hybridoma cells, which secreted monoclonal antibody (MAb) 121 SLE, an IgM showing the following reactivities: (1) by immunodiffusion, MAb 121 SLE and MAb NS 19-9 (a monoclonal antibody directed against a sialylated Lewis(a) antigen called CA 19-9) showed an identical precipitin line with mucin preparation containing this CA 19-9; (2) by immunoradiometric assay, MAb 121 SLE totally inhibited fixation of radiolabelled MAb NS 19-9; (3) by immunoperoxidase, MAb 121 SLE stained the normal gastrointestinal mucosa of Le-positive individuals exclusively, and this staining disappeared after neuraminidase treatment, as observed using MAb NS 19-9. However, the pattern of the staining obtained with MAb 121 SLE differed slightly from that given by MAb 19-9 on the different positive areas of the gastrointestinal mucosae. These differences principally concerned the number of positive epithelial cells and the intensity of their staining; (4) moreover, antibodies against idiotype determinant of NS 19-9 antibody did not react with the antibody 121 SLE. We concluded that MAb 121 SLE is different from the MAb NS 19-9. However, both these antibodies were associated with the same molecular sialylated Lewis(a) structure.

A 42-year-old man presented with systemic lupus erythematosus, universal alopecia and non-pruritic hyperpigmented papular mucinosis. The latter was most evident on acral areas. In hyperpigmented areas of the face the immunofluorescence showed deposits as in LE and with alcian blue and colloidal iron an abundance of mucin was demonstrated in the dermis. A lesion on the back showed only papular mucinosis. Fifteen cases of LE and papular mucinosis reported in the literature are reviewed. Our patient differs with respect to the marked pigmentation of his lesions, their localization and the association with universal alopecia.

A patient is described in whom a papulo-nodular eruption occurred in association with systemic lupus erythematosus. Histopathology disclosed a diffuse deposition of mucin, mainly hyaluronic acid, in the dermis. This, and the 10 similar cases which have been reported in the literature, belong to a distinct clinico-pathological entity for which we propose the eponym of papular and nodular mucinosis of Gold, after the first observer to report it.

Nodular mucin-containing skin lesions in a Mexican woman were present in conjunction with probable systemic lupus erythematosus (SLE). Histologically, the lesions contained features of both lupus erythematosus (LE) and of the mucin deposition diseases. The clinical subsets of LE and the mucinoses are briefly reviewed and the unique clinical nature of the skin lesions in this case are emphasized.

The case of a 48-year-old patient with systemic lupus erythematosus is discussed. Under immunosuppressive therapy, symptomless papules occurred on the shoulders, back, chest and face. Histologically, there were deposits of mucinous matter which produced an intensive blue colour in the HALE-PAS and alcian blue colour test. The epidermal and dermal inflammatory changes which typically occur with lupus erythematosus were absent. Whereas mucin is commonly diagnosed in lupus erythematosus, the clinical manifestation of papulous mucinosis is a rare but diagnostically significant phenomenon, since it can occur without further findings which are typical of lupus erythematosus.

A 38-year-old woman with systemic lupus erythematosus presented to the dermatology department with diffuse nodules and plaques on her face, trunk and extremities. A lesional biopsy revealed large dermal mucin deposits. Papulonodular dermal mucinosis is characterized histologically by diffuse dermal mucin without the classic epidermal or inflammatory changes seen in lupus erythematosus (LE). This rare variant of LE should be distinguished from other cutaneous mucinoses.

A case presentation of a patient with SLE associated with papulonodular mucinosis, generalized lymphadenopathy and splenomegaly is reported, along with a review of the literature. This 24 year old woman had biopsy-proven, skin lesions consistent with dermal mucinosis and a non-homogeneous immunofluorescence pattern. Serum anti-nuclear and anti-DNA antibodies were present and a mesangioproliferative glomerulonephritis was documented. The patient responded dramatically to standard therapy with prednisolone. The nature of the mucin deposits and the pattern of immunofluorescence deposition in the skin are discussed based on the findings reported in the literature.

One of the side effects reported in patients taking thiazide diuretics is photosensitivity. We report two patients who developed lupus-like skin lesions while taking thiazide diuretics. One patient developed erythematous scaling papules, patches and plaques on the upper extremities and trunk resembling subacute cutaneous lupus erythematosus. Histopathology of a skin biopsy from the trunk showed basal cell layer liquefaction and lichenoid interface changes suggestive of lupus erythematosus. The skin lesions resolved completely within two months of discontinuing thiazide therapy. The second patient developed multiple flesh colored urticarial plaques on the trunk one year after beginning thiazide therapy. Slight lichenoid interface changes were noted on a skin biopsy, along with dense mucin deposition in the papillary and deep dermis, suggestive of tumid lupus erythematosus. The skin lesions persisted despite discontinuing thiazide therapy, necessitating systemic corticosteroid treatment. Both patients had circulating anti-SSA/Ro autoantibodies and antinuclear antibodies. These two patients illustrate that thiazide diuretics may induce a cutaneous lupus erythematosus-like adverse reaction and production of anti-SSA/Ro autoantibodies as demonstrated by immunodiffusion, immunoblot and immunoprecipitation testing.

Although microvascular injury has been postulated as the pathogenetic basis of skeletal muscle injury in dermatomyositis (DM), its role in the genesis of the skin lesions, which are said to be difficult to distinguish light microscopically from systemic lupus erythematosus (SLE) and subacute lupus erythematosus (SCLE), has not been analyzed. The authors' intention was to assess the role of microvascular injury in the pathogenesis of skin lesions in DM, SLE, and SCLE. Light microscopic features of biopsies of lesional skin from 20 patients with myopathic DM and 11 with amyopathic DM were compared to eight lesional skin biopsies from eight patients with SLE and 12 lesional skin biopsies from 12 patients with SCLE. Vascular density was compared in the three groups using an immunohistochemical preparation with an antibody to factor VIII. In 12 biopsies from the DM group, and in 19 of 20 lupus erythematosus (LE) specimens, frozen tissue was available. An indirect immunofluorescence methodology was used to detect C5b-9 deposition, and direct immunofluorescence studies for other immunoreactants were performed in standard fashion. Compared with LE, lesions of DM showed a greater degree of endothelial injury, vascular ectasia, and vascular fibrin deposition; there were no differences between myopathic versus amyopathic DM. C5b-9 deposition in vessels was significantly greater in DM than in LE. The superficial vascular plexus density was reduced in lesions of DM versus LE control groups with the greatest reduction observed in myopathic DM. Epithelial injury and mucin was greatest in myopathic DM. Microvascular injury is the apparent pathophysiological basis of skin lesions in DM. Careful attention to microvascular pathology enables distinction of DM from SLE and SCLE. Indirect immunofluorescence testing using a monoclonal antibody to C5b-9 is a valuable tool to distinguish DM from LE in biopsies of lesional skin.

A wide variety of cutaneous manifestations of lupus erythematosus have been reported. Among them, papulonodular eruptions produced by dermal mucin deposition have been recognized as nodular cutaneous lupus mucinosis (NCLM), and many cases have been reported in Japan. A 21-year-old woman with systemic lupus erythematosus (SLE) showed papulonodular eruptions on her back. A skin specimen from the nodule revealed mucin deposition (hyaluronic acid) in the dermis. NCLM should be recognized as a clinical form associated with SLE. The pathogenesis of the mucin deposition in NCLM is still uncertain.
