Background: Cutaneous lymphangiomas are congenital lymphatic malformations, which may involve the skin and subcutaneous tissue and can occur on any cutaneous surface or mucous membrane. Cutaneous lymphangiomas are uncommon, accounting for 4% of all vascular tumours. Dermoscopy is a non-invasive technique, which has greatly improved the diagnostic of cutaneous lymphangiomas. Objective: Our aims were to describe the different dermoscopic patterns of lymphangioma circumscriptum. Methods: We performed a descriptive retro-prospective observational study that included all patients diagnosed with DM in dermatology department over 2 years from 2019 to 2021. Results: A total of 14 cases of lymphangioma circumscriptum were studied. Ranging in age from 3 to 38 years. The most common structure we found in lymphangioma circumscriptum was the presence of lacunae, which were found in 12 of patients (85%) These lacunae were red or dark in colour in 6 cases (50%), yellowish or whitish in 5 cases (35,7%) and multicoloured (yellow, white, red and white in the same patient) in 4 cases (28%).The second most common dermoscopic structure was the presence of vascular structures, which were found in 82% of patients .Other dermoscopic structures were white lines, found in 9 cases (64%) ,the hypopyon sign or two-tone lacunae in 4 (28%). Conclusion: Recognition of dermoscopic features of eybrow trichotillomania is very important and could help to diagnosis of lymphangioma circumscriptum.
