Terra firma-forme dermatosis is a relatively common but probably underestimated entity characterized by asymptomatic cutaneous pigmentation resembling dirty skin. Dermoscopy is a non-invasive diagnostic tool used in the diagnosis of many cutaneous conditions. In this study we aimed to reveal dermoscopic patterns of the entity. A total of 10 patients diagnosed with terra firma-forme dermatosis were enrolled. The most common dermoscopic pattern was polygonal brown clods arranged in a mosaic pattern (N=7). The other patterns observed were seborrheic keratosis-like pattern (N=2) and perifollicular hyperpigmentation (N=1). Rubbing with 70% ethyl alcohol resulted in complete resolution of the lesions in all patients.
地衣状皮肤病变是一种相对常见但可能被低估的病症，其特征为无症状性皮肤色素沉着，类似脏污的皮肤。皮肤镜检查是一种用于诊断多种皮肤疾病的非侵入性诊断工具。在本研究中，我们旨在揭示该病症的皮肤镜表现模式。总共纳入了10例被诊断为地衣状皮肤病变的患者。最常见的皮肤镜表现模式是呈镶嵌状排列的多边形褐色斑块（n = 7）。观察到的其他模式为脂溢性角化病样模式（n = 2）和毛囊周围色素沉着（n = 1）。用70%乙醇擦拭后，所有患者的皮损均完全消退。
