Abstract
Discoid lupus erythematosus (DLE) is the most common type of chronic cutaneous lupus erythematosus. It is more frequent in adult women, particularly black race. Scalp DLE has an earlier onset and a more severe clinical course in black patients compared to Caucasians. Nevertheless, studies on this population remain scarce. The aim of this study was to review the literature and summarize the most frequent trichoscopic findings of scalp DLE among patients with a higher phototype. The main trichoscopic findings of DLE on black scalp are interruption of the honeycomb pattern, reduction, or absence of pinpoint white dots, keratotic follicular plugs and peripilar casts, blue-gray dots in a speckled pattern, and large tortuous arboriform vessels. Knowledge of these and other changes enables an early diagnosis of these individuals, preventing cicatricial sequelae and reducing its impact on quality of life.

Abstract
INTRODUCTION Rosettes are a cluster of shiny white dots in the shape of a four-leaf clover seen under polarized dermoscopic light. Historically, rosettes were primarily reported in actinic keratoses and squamous cell carcinoma. However, rosettes have also been reported in other conditions. OBJECTIVES The objective of this systematic review to elucidate the breadth of diagnoses exhibiting this unique dermoscopic phenomenon. METHODS A review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Literature searches were performed in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and Web of Science, as well as a manual search of the reference lists of screened articles. RESULTS A total of 73 articles met the inclusion criteria. Out of these, 47 distinct diagnoses with rosette were identified. Among neoplastic conditions, keratinizing neoplasms had the highest number of articles reported (N = 19). Discoid lupus was the most commonly reported diagnosis within the inflammatory category (N = 6). Molluscum contagiosum was the predominant diagnosis among infectious entities (N = 3), while acroangiodermatitis was the sole diagnosis reported in the vascular category (N = 1). CONCLUSIONS These findings confirm rosettes are not specific to keratinocytic growths and are observed in a wide range of conditions. Knowledge of the breadth of conditions with rosettes may aid clinicians when developing a differential diagnosis of a growth or an eruption with rosettes under dermoscopy.

Abstract
Subacute cutaneous lupus erythematosus (SCLE) is a condition that might pose a diagnostic challenge. The aim of this study was to assess the usefulness of videodermoscopy in the differentiation of SCLE from other erythematous-desquamative dermatoses. Consecutive patients with SCLE (n = 27), psoriasis (n = 36), nummular eczema (n = 30), mycosis fungoides (n = 26), and pityriasis rosea (n = 20) referred to our Department of Dermatology were recruited for this study. A representative lesion was visualized using a Canfield D200EVO Videodermatoscope (Canfield Scientific GmbH, Bielefeld, Germany) and evaluated for the following parameters: vessels (morphology and distribution), scales (color and distribution), follicular findings, colors and morphologies, and presence of specific clues. SCLE was predominantly characterized by a polymorphous vascular pattern (92.6%) of unspecific distribution (92.6%) over a pink-red background (74.1%). Gray-brown dots were present in 10 (37.0%) cases, and pigmentation was noted in 15 (55.6%) patients, including peripheral pigmentation in 7 (25.9%) patients. Videodermoscopic evaluation showed significant differences between SCLE and psoriasis, which was characterized by regularly distributed dotted vessels. Although some common dermoscopic features with MF were noted, the presence of yellow structureless areas and red dots/globules favored the diagnosis of MF. In conclusion, a polymorphic vascular pattern, especially in association with gray-brown dots and/or peripheral pigmentation, is a valuable clue for the differentiation of SCLE from other erythematous-desquamative dermatoses.

Abstract
Dermoscopy is an easily accessible, noninvasive diagnostic tool, originally used in the differentiation of benign and malignant skin tumors. Other structures beside pigment content observed by dermoscopy, e.g., scaling, follicles, or vessels, may present in a specific pattern in different dermatoses. Recognition of these patterns may aid the diagnosis of inflammatory and infectious dermatological conditions. The aim of this article is to review the distinct dermoscopic features of granulomatous and autoimmune skin diseases. Diagnosis of granulomatous skin disorders is based on the histopathological examination. The dermoscopic picture of these diseases (cutaneous sarcoidosis, granuloma annulare, necrobiosis lipoidica, and granulomatous rosacea) show many similarities; however, there are some differences to note between the dermatoses, mainly in granuloma annulare. The cornerstones of the diagnostic process of autoimmune skin diseases (morphea, systemic sclerosis, dermatomyositis, cutaneous lupus erythematosus) include the clinical picture, immunoserology, and histology; however, dermoscopy may aid the diagnostic process and follow-up of the patients. For those diseases, where vascular abnormalities play an important role in the pathogenesis, videocapillaroscopy is used for examination of the microcirculation at the nailfold capillaries. Dermoscopy can be an easy-to-use everyday diagnostic tool in clinical practice regarding granulomatous and autoimmune skin diseases. Although punch biopsy is inevitable in many cases, the distinct dermoscopic structures can aid the diagnostic process.

Abstract
INTRODUCTION Chronic cutaneous lupus erythematosus (CCLE) comprises three major clinical variants: discoid lupus erythematosus (DLE), chilblain lupus erythematosus (CHLE), and lupus erythematosus profundus, also referred to as lupus erythematosus panniculitis (LEP). The aim of the current study was to systematically describe the dermoscopic features of CCLE in Polish patients with Fitzpatrick skin phototypes I-III. METHODS The videodermoscopic images from patients with various clinical variants of CCLE (DLE, CHLE and LEP) were reviewed. Predefined parameters for dermoscopic evaluation in general dermatology were used to describe the findings in lesions located beyond the scalp. In the analysis of trichoscopic findings in lesions located on the scalp, dermoscopic features of follicular openings, hair shafts, the perifollicular surface, the interfollicular surface and vessel morphology were considered. Based on personal experience, several additional dermoscopic and trichoscopic characteristics were included in the analysis. RESULTS A total of 85 lesions from 26 patients (16 women and 10 men; mean age 40.8 ± 11.2 years) were assessed. DLE on glabrous skin showed polymorphous vessels (89.1%), pink-red background (70.9%), follicular plugs (67.3%) and white scaling (58.2%), while scalp DLE was characterized by polymorphous vessels (83.3%), yellow dots (66.7%), follicular plugs (55.6%) and a reduced number of follicles (55.6%). Labial DLE (n = 2) showed linear branched and linear curved vessels, white structureless areas, red structureless (hemorrhagic) areas and red dots/globules. White scaling (61.1% vs. 34.1%; p = 0.042), gray-brown dots/globules (44.4% vs. 12.2%; p = 0.015) and peripheral pigmentation (100.0% vs. 46.2%; p = 0.036) were significantly more common in long-lasting (> 1 year) DLE lesions. CHLE (n = 5) presented with polymorphous vessels, white scales, pink-red background, red structureless areas and red dots/globules. LEP showed polymorphous vessels, white-yellow scales, follicular plugs, white structureless areas and red hemorrhagic areas. CONCLUSIONS Dermoscopy might be useful in the preliminary diagnosis of DLE, and its role in the diagnosis of CHLE and LEP needs further elucidation.

Abstract
Cutaneous lupus erythematosus (CLE) is divided into the following four clinical subtypes: acute CLE (ACLE), subacute (SCLE), chronic CLE (CCLE) and lupus erythematosus tumidus (LET). The aim of this study was to describe the dermoscopic patterns of CLE by clinical variant. A total of 54 Caucasian patients from Poland (ACLE = 10; SCLE = 11; CCLE = 26; LET = 7) were included. The predefined parameters for dermoscopic assessment in inflammatory dermatoses were analyzed separately by two dermatologists. Under dermoscopy, all the variants of CLE showed predominantly polymorphous vessels on a pink−red background within the lesional skin. Dotted vessels, in association with other vessel morphologies, were observed more frequently in SCLE than in the other subtypes of CLE, but the difference did not reach statistical significance (p = 0.07). The findings associated with hair follicles, including rosettes (p = 0.02), follicular plugs (p = 0.01), follicular red dots (p < 0.01), perifollicular white halos (p < 0.01) and dermoscopic features corresponding to scarring, including white (p = 0.01) and pink (p < 0.01) structureless areas, were significantly more common in CCLE than in other variants of CLE. A lack of scaling, pigmentation, erosions and crusting were observed in all the cases of LET. The role of dermoscopy as an auxiliary tool in the differential diagnosis of CLE needs further elucidation.

Abstract
BACKGROUND (Video)dermoscopy is a non-invasive diagnostic technique that has a well-established role in dermatooncology. In recent years, this method has also been increasingly used in the assessment of inflammatory dermatoses. So far, little is known about the (video)dermoscopic features of dermatomyositis (DM). METHODS Consecutive patients with DM were included in the study and videodermoscopic assessments of the nailfolds, scalp, and active skin lesions were performed. RESULTS Fifteen patients with DM (10 women and 5 men) were included. Capillaroscopy showed elongated capillaries (90.9%), avascular areas (81.8%), disorganized vessel architecture (81.8%), tortuous capillaries (72.7%), dilated capillaries (72.7%), and hemorrhages (72.7%). The trichoscopic findings included linear branched vessels (80.0%), linear vessels (60.0%), linear curved vessels (53.3%), perifollicular pigmentation (40.0%), perifollicular erythema (33.3%), scaling (20.0%), white (20.0%) or yellow (20%) interfollicular scales, and white (20.0%) or pinkish (13.3%) structureless areas. Polymorphic vessels of an unspecific distribution and white or pink structureless areas were frequently observed under dermoscopy in cutaneous manifestations of DM, including Gottron's papules and Gottron's sign. CONCLUSIONS Dermoscopy of the nailfolds (capillaroscopy), scalp (tricoscopy), and active cutaneous lesions may be of value in the preliminary diagnosis of DM.
