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.

We present two Japanese cases of involutional lipoatrophy. The first case is that of a 30-year-old woman, who first appeared at our hospital complaining of a localized, well-demarcated depression, approximately 3 x 4 cm in size, normal to slightly erythematous in coloration, on the lateral side of the left upper arm (Fig. 1a). The condition was asymptomatic, and she had noticed this anomaly a month prior to consultation. She received intramuscular injections of corticosteroids of unknown dosage at the affected site for the treatment of allergic rhinitis 4 months prior to her present consultation. The second patient, a 23-year-old woman, appeared at our hospital complaining of a similar macule 4 x 4 cm in size, which she noticed several weeks prior to her most recent consultation. She had no history of injury or injection at the site before the development of the condition (Fig. 1b). She had been under treatment for atopic dermatitis since early childhood and was treated only with topical applications of white petrolatum containing 2% salicylic acid for the past several years. In order to rule out the possibility of acquired partial lipodystrophy associated with localized scleroderma, lupus profundus and the other connective tissue diseases, a histological examination was performed for both patients. Histopathological analysis of the region exhibited a well-defined fat lobule composed of numerous small adipocytes (Fig. 1c) embedded in hyaline connective tissue. Edema and dilated capillaries were noticeable in the subcutaneous tissue surrounding the area. Inflammatory cells were not prominent, although mononuclear cells were observed in both patients. No epidermal change was seen in either patient. Direct and indirect immunofluorescence studies revealed no deposits of immunoreactants in the skin of either patient. Immunohistochemical studies with the antibody against macrophage (anti-CD68 antigen; DAKO.) showed that positive cells were scattered around blood vessels and shrunken lipocytes in the subcutaneous tissues (Fig. 1d). Most of these cells in the fat lobules were also positive for mucin stains such as Alcian blue. No abnormal findings came to light in the ordinary hematological and blood chemistry examinations of both patients. The autoantibody screening tests using antinuclear, anti-DNA, anticentromere, and anti-Scl-70 antibodies were negative in both patients.

Skin disease in patients with lupus erythematosus may be subdivided into two broad categories - those represented by a 'specific' histopathology, the interface dermatitis, and those with changes that are not specific to lupus erythematosus, for example, vasculitis, mucin infiltration, etc. The specific skin lesions that are most common are discoid lupus erythematosus (DLE) and subacute cutaneous lupus erythematosus (SCLE). Evaluation will allow the treating physician to assign a prognosis. Cutaneous lesions can generally be managed with standard therapies. Patients with discoid LE and subacute cutaneous LE are generally photosensitive, and therefore sunscreens, protective clothing and behavioural alteration should be discussed with all patients. Topical corticosteroids are a standard form of therapy, but 'newer' agents such as retinoids, calcipotriene and tacrolimus might be effective. Antimalarial agents are generally effective. Attempts to reduce or stop smoking may aid in the control of cutaneous LE. The choice of alternative therapy is personal, and discussions of the risks and benefits should be carefully documented.

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.

We describe a 10-year-old Japanese girl presenting linear alopecia on the scalp and forehead. Histological examination showed fat degeneration with mucin deposit and periappendageal infiltrate of mononuclear cells. We diagnosed her as having linear lupus erythematodes profundus with a linear configuration following the lines of Blaschko.

A 9-year-old girl was initially seen with bilateral mildly pruritic plantar skin lesions. Skin biopsy demonstrated a superficial and deep perivascular lymphoid infiltrate with mucin but was not specific. Laboratory evaluation revealed a mildly elevated antinuclear antibody and mild leukopenia. Over the following year, an annular skin lesion developed in the preauricular area, her antinuclear antibody titer rose, and she was found to have positive anti-SS-B antibodies. She responded to oral hydrochloroquine with resolution of her skin lesions. This report highlights the unusual presentation of a case of chronic cutaneous lupus with a plantar skin eruption.

"Dry eye syndrome" is a common disorder of the tear film that results from inadequate tear production, excessive tear evaporation or abnormality in mucin or lipid components of the tear film. A number of 53 patients suffering from dry eye syndrome were followed up for a period of 18 months. The study group was heterogeneous, including a lot of conditions accompanied by dry eye syndrome: Syogren's syndrome, lupus erythematous, ocular rosacea, patients with systemic treatments with antidepressants, betablockers, diuretics, oral contraceptives, glaucomatous patients with topical beta-blockers, postmenopausal women, aging people, computer users and long-term contact lens wearers. The therapeutical options were dictated by the severity of the syndrome: substitution therapy, treatment of the underlying eyelid diseases, modifying of the environmental conditions and treatment of the complications in the most severe cases. The new pathological approach is innovative and it may provide a real therapeutical measure for this condition: topical A Cyclosporine and androgen drops.

Lupus tumidus is a rare sub-type of chronic cutaneous lupus erythematosus characterized by dermal plaques in which excessive mucin accumulates early in disease process. We report a middle aged women having succulent, edematous and persistent plaque over her face for five years that was not responding to various empirical treatments offered to her. Finally, on clinico-pathological basis, it was diagnosed as a case of tumid lupus erythematosus (TLE) and she responded satisfactorily to the treatment regimen including oral steroids, chloroquine and application of sun screen.

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.

A 30-year-old woman with subacute cutaneous lupus erythematosus presented with a facial eruption, painful and swollen ulcers of her digits, and asymptomatic lesions on her abdomen. The laboratory findings were consistent with subacute cutaneous lupus erythematosus with an anticardiolipin antibody. A biopsy specimen of the asymptomatic lesions on her abdomen showed mucin within the upper reticular dermis. Papulonodular mucinosis is a rare but well-documented finding associated with systemic and cutaneous forms of lupus erythematosus. The etiology and pathogenesis of this finding remain to be elucidated.
