“…21 Zaballos et al described the dermatoscopy of three lichen aureus patients and their findings were similar, entailing a coppery-red background, round to oval red dots, globules and patches, grey dots, and a partial network of interconnected pigmented lines. 14 In our study, the majority of cases were SD, and the most significant findings were coppery-red pigmentation in the background (97%), red globules (75%), red dots (69%), brown dots (53%), and a reticular network (34%).…”

BackgroundPigmented purpuric dermatosis is a chronic skin disorder of unknown aetiology characterised by symmetrical petechial and pigmented macules, often confined to the lower limbs. The aetiology of pigmented purpuric dermatosis is unknown. Dermatoscopy is a non-invasive diagnostic technique that allows the visualisation of morphological features invisible to the naked eye; it combines a method that renders the corneal layer of the skin translucent with an optical system that magnifies the image projected onto the retina.ObjectivesThe aim of this study is to investigate the dermatoscopic findings of pigmented purpuric dermatosis.MethodsThis study enrolled patients diagnosed histopathologically with pigmented purpuric dermatosis who had dermatoscopic records. We reviewed the dermatoscopic images of PPD patients who attended the outpatient clinic in the Istanbul Dermatovenereology Department at the Bezmialem Vakıf University Medical Faculty.ResultsDermatoscopy showed: coppery-red pigmentation (97%, n = 31) in the background, a brown network (34%, n = 11), linear vessels (22%, n = 7), round to oval red dots, globules, and patches (69%, n = 22; 75%, n = 24; 34%, n = 11; respectively), brown globules (26%, n = 8) and dots (53%, n = 17), linear brown lines (22%, n = 7), and follicular openings (13%, n = 4).ConclusionTo our knowledge, this is the first study to report the dermatoscopy of pigmented purpuric dermatosis. In our opinion, dermatoscopy can be useful in the diagnosis of pigmented purpuric dermatosis.

“…Schamberg's disease, also known as progressive pigmented purpuric dermatosis, is the most common form of PPD and typically shows a caudal-cranial progression of the red-brown pigmentation. Lichen aureus is an uncommon type of PPD and is clinically characterized by solitary or multiple rust macules, papules or plaques [3,4].…”

A b s t r a c tIntroduction: Pigmented purpuric dermatosis (PPD) describes a cutaneous eruption that presents with asymptomatic or pruritic macules, and petechiae with red and brown pigmentation. Dermoscopy is a non-invasive diagnostic method making a more detailed examination possible and provides important clues to many dermatologic conditions. There are few original studies focusing on the dermoscopic aspect of PPD apart from case reports. Aim: To identify dermoscopic findings of pigmented purpuric dermatosis, which will facilitate diagnosis by reducing the use of invasive procedures. Material and methods: The study included the patients with histopathologically confirmed pigmented purpuric dermatosis. Demographic, clinical and dermoscopic features of all the cases were retrospectively reviewed. Results: The study enrolled 15 (60%) men and 10 (40%) women. The mean age of the patients was 42 (age range: 28-72). The most common dermoscopic findings were red globules and red dots which were observed in all the cases (100%), followed by coppery brown background (72%), brown lines reticular (40%) and subtle brown dots (40%). The other findings were brown circles (32%), red circles (32%), grey dots (32%), red background (8%), serpentine vessels (8%), rosette structures (8%), thick brown lines (4%), and thick linear vessels (4%). Conclusions: The characteristic dermoscopic findings of PPD have been defined in the relevant literature. Here we have identified some dermoscopic findings which have not been described previously: red circles, brown circles, rosette structures, light brown background and red background. Dermoscopic examination may facilitate the diagnostic process by reducing the use of invasive methods.

“…Features (1), (3) and (4) were observed in our patient. Moreover two artilces described the same dermoscopic features in two adults with LA [3,4]. Saito et al reporte, also, the same dermosopic findings in a 3-year-old boy diagnosed with [6].…”
