Dermoscopic examination revealed the presence of diffuse and homogeneous bluish pigmentation. We ruled out primary melanoma due to the absence of atypical network, vessel, irregular globules and dots, pseudopods regression areas, and we excluded trichoepithelioma due to abscence of large blue‐gray ovoid nests, leaf‐like areas, and arborizing vessels [Figure 1b]. Considering the sudden onset, the number and appearance of the lesions might pose problem of differential diagnosis of cutaneous metastases from occult malignant melanoma. However, clinical examination revealed neither atypical pigmentation nor partially regressed lesions. No regional lymphadenopathy was found.
