BACKGROUND: Estrogens have a modulatory effect on several immune responses, many of which are correlated to autoimmune diseases. Estrogens act through binding to their receptors, and an overexpression of these receptors has been identified in patients with different autoimmune diseases. Here we analyzed the association of a putative functional genetic variant in the main estrogen receptor (ERα) gene (ESR1), and the susceptibility to clinical findings and severity of SLE. METHODS: A total of 426 individuals (266 healthy controls and 160 SLE patients) were genotyped for the polymorphism rs2234693 in the ESR1 gene...

Cutaneous lupus erythematosus (CLE) is a disfiguring and common manifestation in systemic lupus erythematosus (SLE), and the etiology of this predisposition for cutaneous inflammation is unknown. Here, we sought to examine the keratinocyte as an important source of IL-6 and define the mechanism for its increased production in CLE. Evaluation of discoid and subacute cutaneous lupus erythematosus lesions revealed significant epidermal upregulation of IL-6 when compared with control via real-time PCR and immunohistochemistry...

Cutaneous Squamous cell carcinoma (SCC) is the second most common form of non-melanotic skin cancer after basal cell carcinoma (BCC). It is a well-known complication of discoid lupus erythematosus (DLE) and usually favours the depigmented lesions located over sun-exposed areas. The clinical course of this complication may be aggressive, with a high risk of mortality. Literature describes numerous case reports of SCC complicating the lesions of DLE but mutilating SCC is rarely mentioned. Here in, we report a rare case of mutilating squamous cell carcinoma arising in an early (two years duration) lesion of DLE...

A 50-year-old African American male with Discoid Lupus Erythematosus (DLE) presented to the dermatology clinic for a rapidly enlarging left cheek mass. The mass failed to resolve with conservative measures. A biopsy revealed poorly differentiated Squamous Cell Carcinoma (SCC). He was referred to Head and Neck Surgery and successfully underwent a resection with free flap reconstruction. Postoperatively he did well. Squamous cell skin carcinomas arising from lesions of Discoid Lupus are rare and aggressive tumors with greater likelihood of metastases...

A 69-year-old man with rheumatoid arthritis developed a discoid rash on his face years after the initiation of treatment with adalimumab. Serological tests were positive for antinuclear antibodies (ANA) and autoantibodies against Sjögren's syndrome-related antigen A (SSA). We diagnosed him with 'lupus-like syndrome'. After discontinuation of the adalimumab therapy and the use of topical corticosteroids, his symptoms resolved quickly.

Overlap syndromes are known to occur with connective-tissue diseases (CTDs). Rarely, the overlap occurs at the same tissue site. We report the case of a patient with clinical and histopathologic findings consistent with the presence of discoid lupus erythematosus (DLE) and localized scleroderma within the same lesions. Based on our case and other reported cases in the literature, the following features are common in patients with an overlap of lupus erythematosus (LE) and localized scleroderma: predilection for young women, photodistributed lesions, DLE, linear morphology clinically, and positivity along the dermoepidermal junction on direct immunofluorescence...
