“…Several tumors might clinically and dermoscopically mimic JXG. The most challenging differential diagnoses include primary cutaneous B-cell lymphoma, which may have a pinkish background, white circles, linear arboriform vessels, and scales [19]; and solitary reticulohistiocytoma, which may present a yellowish background with a peripheral erythematous border, and linear arboriform vessels in a radiated arrangement, similar to the “setting sun” pattern of JXG [20, 21].…”

Background: Dermoscopy is useful for the evaluation of juvenile xanthogranuloma (JXG). The classical “setting sun” pattern is characteristic of JXG, but its sensibility appears to be limited. An extensive description of other dermoscopic findings is not available in the literature. Objectives: The aim of this study was to valuate and describe the clinical and dermoscopic characteristics of a series of JXG cases. Methods: This is a retrospective descriptive study, including cases with histopathologic diagnosis of JXG, and the availability of clinical and dermoscopic images, assessed for the presence of dermoscopic features based on the available literature. Results: A total of 17 lesions were analyzed. 70.6% showed global symmetry, 35.3% presented the typical “setting sun” pattern. All lesions showed yellow-orange and/or pink-red structureless color. Other dermoscopic features were yellow globules (35.3%), shiny white streaks (23.5%), brown globules (17.6%), pale-brown network (11.8%), negative network (11.8%), erosion/ulceration (11.8%), rosettes (5.9%), and hemorrhage (5.9%). Scales were seen in 64.7% of patients. Vascular structures were observed in all the lesions, mostly in an irregular distribution (76.5%). The observed vessel types were dotted (52.9%), linear (52.9%), branching-arboriform (29.4%), comma-like (23.5%), hairpin-like (17.6%), globular (17.6%), coiled (11.8%), and milky-red globules (5.9%). Conclusions: Symmetry, yellow/orange-pink/red color, yellow globules, shiny white streaks, and irregularly distributed different types of vascular structures are the main dermoscopic features of JXG. This is the largest dermoscopic registry of JXG published to date.

“…2) [2]. We propose dermoscopy as an aid in the management of ES to help differential diagnosis from other clinically similar but more serious entities, such as urticaria pigmentosa mastocytosis, lichen planus, and reticulohistiocytosis, presenting, respectively, with dermatoscopical reticulate lines, reticulate white lines, and "setting sun sign" with homogeneous yellow central area and peripheral pink-orange color, to schedule the required confirmatory biopsy in due time without haste [3,4].…”

Introduction: Eruptive syringomas (ES) are a rare variant of syringomas, benign adnexal tumors of eccrine sweat glands’ ducts. They mostly affect young-to middle-aged women, but rarely they may also occur in the elderly, requiring generally no specific treatment. Case Presentation: We present the case of a 76-year-old woman with sudden onset of ES. Clinical examination evidenced brown-to-orange papules and plaques on the anterior neck, corresponding dermatoscopically to orange-brownish structureless areas, with barely hinted peripheral incomplete network, superimposed on areas of light pink. Histology showed dermal proliferation of epithelial cells forming cords and ductules, confirming the clinical-dermoscopic suspect of ES. The lesions remained stable at 12-month follow-up without treatment. Discussion: This case highlights the role of dermoscopy to help differentiate ES from other clinically similar but more serious entities, such as histiocytosis, mastocytosis, and lichen planus, and to schedule the required confirmatory biopsy in due time without haste.

“… Dotted vessel and light-brown globules on a yellow background[ 2 ] Uniformly yellow central area and a pink-orange colour in the periphery—”Setting sun sign”[ 3 ] Crown vessels and white dots were demonstrated along with the presence of light-yellow background in a recent study[ 4 ] as a result of congestion of capillaries and veins. Crown vessels consists of homogenously curved, slightly arborizing vessels which meet at the centre of the lesion.…”
