“…Previously, whitish areas under dermoscopy had been seen in dermatofibromas, corresponding to increased collagen and fibrosis in the upper dermis. [29–36] The whitish areas in dermatofibromas had been previously noted to be more prominent under polarized dermoscopy compared to those under nonpolarized dermoscopy, which could be a result of greater penetration of light into the deeper layers of the dermis using polarized dermoscopy.

Livedoid vasculopathy (atrophie blanche) is a form of thrombotic vasculopathy. It is characterized by small ulcers that become crusted, and heal after several months to produce white atrophic scars. The most commonly affected sites are the lower legs, in particular the dorsum of the feet and ankles. To date, the dermoscopic features of livedoid vasculopathy have not been clearly described in the literature. In this observational study, we sought to evaluate the dermoscopic patterns of livedoid vasculopathy and determine whether the dermoscopic features are associated with certain histopathological characteristics. We evaluated 9 patients with livedoid vasculopathy by dermoscopy. Skin biopsy specimens were stained with hematoxylin and eosin for histopathologic examination, and dermoscopic features were correlated with histopathological characteristics. In the majority of patients with livedoid vasculopathy, examination with dermoscopy revealed central crusted ulcers or ivory white areas associated with peripheral pigmentation in a reticular pattern. In addition, increased vascular structures including linear and glomerular vessels were found. On histopathological examination, the central ivory white areas correlated with dermal fibrosis, the reticular pigmentation corresponded to epidermal basal layer hyperpigmentation or melanin within melanophages in the dermal papillae, and the vascular structures correlated with dilatation and proliferation of capillaries in the upper dermis. In summary, the most common dermoscopic features of livedoid vasculopathy identified in this study were central crusted ulcers or ivory white scar-like areas associated with peripheral reticular pigmentation and increased vascular structures. The characterization of dermoscopic criteria for livedoid vasculopathy may improve the accuracy in the clinical diagnosis and follow-up of this disease.

“…Additional dermoscopic patterns of dermatofibroma include crystalline structures or yellow globular structures. 13 When differentiating DMC from dermatofibroma, the absence of a peripheral pigment network and presence of vascular patterns can be helpful clues. Warts can be easily differentiated from DMC because of the hypertrophic epithelium and multiple black or red dots on dermoscopic examination (Fig.…”

Digital mucous cysts (DMC) are common benign myxoid cysts typically located on the fingers and toes. Recently, dermoscopic patterns of DMC were reported. However, only a small number of cases were described in the published work; therefore, information on this topic is scarce in the published work. We investigated dermoscopic patterns of histopathologically diagnosed DMC. In total, 23 cases were enrolled in this study. Polarized dermoscopy revealed vascular patterns in 13 cases (56.5%), with arborizing vascular patterns, dotted vessels, linear vessels and polymorphous vessels in eight (34.8%), three (13.0%), one (4.3%) and one (4.3%) case, respectively. Red-purple lacunas, ulceration, nail dystrophy and white shiny structures were detected in five (21.7%), two (8.7%), seven (30.4%) and six cases (26.1%), respectively. We report the largest case series regarding dermoscopic features of DMC to date. Dermoscopy can be used as a helpful adjuvant and non-invasive tool in the diagnosis of DMC.

“…Ferrari () described in 130 patients atypical dermoscopic features of DF similar to other skin conditions, such as melanomas (16.2%), vascular tumors (4.6%), basal cell carcinoma (3.8%), collision tumors (2.3%), and psoriasis (2.3%). Espasandín‐Arias () showed the dermoscopic variability of dermatofibromas: comedo‐like openings mimicking a seborrheic keratosis; prominent linear vessels in radial arrangement in early dermatofibroma; dotted vessels with peripheral collarette and scaly surface; central white with globular‐like structures; crystalline structures; globular blue areas or blue homogeneous pigmentation; yellow globular structures surrounded by a brownish homogeneous pigmentation in a DF with sebaceous component and lesion with a multicomponent pattern with atypical pigment network, a central white scarlike area, and linear irregular vessels. So sometimes the formulation of the diagnosis with dermoscopy alone becomes complicated.…”
