In 2-8% of patients with melanoma, the first clinical manifestation of the disease may be skin metastasis. In these cases, differential diagnosis with the primary melanoma, benign melanocytic lesions, and other malignant and benign skin growths is particularly challenging. For this reason, the dermatologist's approach to cutaneous metastases of malignant melanoma calls for knowledge of the great morphological variety of these lesions. Dermoscopic characteristics associated with CMMMs have not yet been codified. The aim of the present review is to provide additional information about dermoscopic aspects of these skin lesions.

Basal cell carcinoma (BCC) is the most prevalent type of skin cancer worldwide. Despite its low metastatic potential, certain subtypes present an aggressive clinical course. Part II focuses on the different dermoscopic patterns observed in BCC, depending on the lesion subtype, its location on the body, the patient's age, the size of the tumor, and skin phototype.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.
