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.
