20.500.12556/DiRROS-29918 Nail psoriasis or trachyonychia? can dermoscopy differentiate them? Nail psoriasis or trachyonychia Trachyonychia is a disease of the nail matrix that can present as either opaque or shiny trachyonychia. Although it is often idiopathic, it can be associated with conditions such as alopecia areata (AA), psoriasis, and lichen planus. Isolated nail psoriasis (NP) can mimic trachyonychia, making diagnosis challenging. Dermoscopy, a non-invasive imaging technique, has proven useful in identifying NP features. This report presents two cases: one with isolated psoriatic trachyonychia and another with AA-associated trachyonychia. In both cases, jagged erythema and teardrop-shaped spots on the lunula were observed, with the latter being described for the first time in trachyonychia literature. These findings suggest a potential link between inflammation and nail matrix pathology, warranting further investigation. nail psoriasis trachyonychia dermoscopy kožne bolezni psoriaza luskavica trahionihija dermoskopija nohtna posteljica true false true Združenje slovenskih dermatovenerologov Angleški jezik Slovenski jezik Na spletni strani revije navedeno: Acta Dermatovenerologica Alpina, Pannonica et Adriatica (ISSN 1318-4458) is an open access medical journal published quarterly by the Association of Slovenian Dermatovenerologists (https://acta-apa.mf.uni-lj.si/index.php); Authors publishing in our journal retain copyright of their work under the Creative Commons Attribution License (CC BY 4.0).
