Hypertrophic discoid lupus erythematosus can resemble keratoacanthoma histomorphologically. We describe a unique case of eruptive keratoacanthomatous scaly papules in a 56-year-old woman with discoid lupus erythematosus. We review the literature and conclude by discussing important histologic features and useful immunostains to consider when attempting to discern the underlying identity and pathogenicity of such lesions.

BACKGROUND: Accurate identification of follicular streamers versus follicular scars on horizontal scalp biopsy sections is important to differentiate between cicatricial and noncicatricial alopecias. However, distinguishing between them can be difficult especially in nonoptimal specimens. The utility of elastic Verhoeff-Van Gieson (EVG) stain in cicatricial alopecias has been described on vertical sections, but its evaluation on horizontal sections has not been performed. METHODS: Sixty-four cicatricial alopecias (25 lichen planopilaris, 29 central centrifugal cicatricial alopecias, and 10 discoid lupus erythematosus) and 53 noncicatricial alopecias (34 androgenic alopecia, 8 telogen effluvium, and 11 alopecia areata) were identified, and EVG staining was performed on horizontal sections...

Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics...

A 46-year-old woman with a 30 pack-year smoking history presented with a worsening eruption on the left cheek that failed to improve with metronidazole gel. The cutaneous eruption spread to most of her face and did not respond to a brief tapering course of prednisone. During the initial evaluation at our institution, approximately 6 weeks after the onset of the cutaneous eruption, the patient had erythematous, crusted plaques on her face and scalp (Figure 1A); they were also present on the V-area of the anterior aspect of the neck and upper region of the chest, the shoulders, and the arms, with isolated lesions on the trunk and legs...

Lips display various benign and malignant lesions. Considering their functional and cosmetic importance, noninvasive diagnostic methods are required. In vivo reflectance confocal microscopy (RCM) has already been reported to be useful in the evaluation of various skin lesions. The aim of this study was to define the RCM features of nonmelanocytic lip lesions, compare them with healthy lip, and demonstrate the applicability of RCM as a noninvasive diagnostic method for nonmelanocytic lip lesions. Sixty-seven patients with premalignant/malignant, inflammatory, and infectious lip lesions and twenty-one healthy volunteers were included in the study...

INTRODUCTION: Many studies have shown that some SNPs might be a risk factor for systemic lupus erythematosus (SLE), but little is known about potential susceptibility loci of the skin types of the disease. Discoid lupus erythematosus (DLE) is the most common form of the cutaneous lupus erythematosus. Nevertheless, a genetic contribution to DLE is not fully recognized. AIM: We aimed to analyze three SNPs located in the STAT4 (rs7574865), ITGAM (rs1143679) and TNXB (rs1150754) genes in both DLE and SLE patients from Poland...

A 35-year-old woman with discoid lupus erythematosus (DLE) was admitted at 11 weeks' gestation with a persistent fever. Laboratory studies revealed pancytopenia, elevated liver enzymes, and hyperferritinemia. Bone marrow aspiration confirmed the diagnosis of hemophagocytic syndrome (HPS). She had no findings of infection or active systemic lupus erythematosus. The administration of high-dose corticosteroids resolved the clinical and laboratory findings. She delivered a healthy baby at 35 weeks' gestation. This case suggests that DLE can be a predisposing factor for pregnancy-induced HPS...

Discoid lupus erythematosus (DLE) is a chronic form of cutaneous lupus that can cause permanent scarring. Treatment of DLE includes protection from sunlight and artificial sources of ultraviolet light, as well as systemic and topical medications. The first-line standard therapies are antimalarials and topical steroids. Other systemic therapies include systemic steroid, azathioprine, dapsone, and immunosuppressive agents. Topical tacrolimus and pimecrolimus have also been evaluated. Recent studies reported that several treatments, including pulsed dye laser, CO2 laser, intense pulsed light (IPL), and 1,064-nm long-pulse neodymium-doped yttrium aluminum (Nd:YAG) have been used for the cosmetic treatment of DLE...

To inform our ongoing efforts to develop defining features to be incorporated into a novel set of classification criteria for discoid lupus erythematosus (DLE), we conducted a literature review using the Ovid MEDLINE database. A search was performed to identify studies reporting criteria used to distinguish DLE from other cutaneous lupus erythematosus subtypes. We examined which clinical, histopathologic, and serologic features have data to support their use as effective features in distinguishing DLE from other potential disease mimickers and cutaneous lupus subsets...

Currently, no standardized classification criteria exist for cutaneous lupus erythematosus. With increased interest in studying cutaneous lupus erythematosus, specifically discoid lupus erythematosus, it is our aim to apply previously adopted methods from rheumatology to dermatologic diseases to develop feasible, validated, and standardized classification criteria useful in both academic and community practice. Here we report the progress to date to define discoid lupus erythematosus using clinical, histopathologic, and serologic features by means of a Delphi method-using a series of iterative questionnaires sent to expert stakeholders...

Cutaneous lupus erythematosus (CLE) can be an individual disease only involving skin, or presents as part of the manifestations of SLE. A small proportion of CLE may progress into SLE, however, the underlying pathogenic mediators remain elusive. By only including researches that clearly described if the subtypes of CLE presented by enrolled subjects was associated with or without SLE, we provided an overview of antibodies, inflammatory cells and inflammatory molecular mediators identified in blood and skin that were possibly involved in lupus skin damages...

Background Epidemiological studies in systemic lupus erythematosus have been reported in the literature in many countries and ethnic groups. Although systemic lupus erythematosus in Jamaica has been described in the past, there has not been a detailed evaluation of systemic lupus erythematosus patients in urban Jamaica, a largely Afro-Caribbean population. The goal of this study was to describe the clinical features, particularly disease activity, damage index and immunological features, of 150 systemic lupus erythematosus subjects...
