7/21/2023 0 Comments Pinpoint red dots on skin lupusLaboratory evaluation ruled out systemic involvement in all cases. None of the patients had received previous topical or systemic treatment. All patients were white, and the duration of the disease ranged from 2 to 18 months. The diagnosis of DLE was confirmed by pathologic examination and immunofluorescence at our institution. Two of them also had DLE lesions on the face. Since 2007, follicular red dots have been noticed in the alopecic scalps of 5 patients, 4 women and 1 man (age range, 29-66 years) affected by discoid lupus erythematosus (DLE) of the scalp. The study was approved by the ethics committee of our institution (University of Bologna, Bologna, Italy). Recognition of this distinctive dermoscopic pattern may help the clinician to differentiate DLE from other diseases causing cicatricial alopecia. Retrospective blinded evaluation of the dermoscopic images of 155 patients with cicatricial alopecia suggests that follicular red dots are a specific feature of DLE because the pattern was not identified in the images of cicatricial alopecia resulting from other diseases.Ĭonclusions The follicular red dot pattern is a specific feature of scalp lesions of active lupus erythematosus of the scalp. In the pathologic findings, red dots correspond to widened infundibula plugged by keratin and surrounded by dilated vessels and extravasated erythrocytes. Follicular red dots appear as erythematous polycyclic, concentric structures, with a diameter ranging from 0.16 to 0.47 mm, regularly distributed in and around the follicular ostia. Observations We describe the morphologic and pathologic features of a new dermoscopic pattern, referred to as “follicular red dots,” that was found in scalp lesions of 5 patients with active discoid lupus erythematosus (DLE). Shared Decision Making and Communicationīackground Scalp dermoscopy plays an important role in the diagnosis of hair and scalp disorders, and specific dermoscopic patterns have recently been associated with several disorders causing noncicatricial alopecia, such as androgenetic alopecia, alopecia areata, trichotillomania, and tinea capitis.Scientific Discovery and the Future of Medicine.Health Care Economics, Insurance, Payment.Clinical Implications of Basic Neuroscience.Challenges in Clinical Electrocardiography.
