Basal cell carcinoma miming cutaneous melanoma

In the last decades, the incidence of skin cancer is in continuous growth, but the mortality remains at the same level thanks to the new imaging diagnosis methods and surgical treatment. A real problem regarding differential diagnosis between cutaneous melanoma and non-melanotic skin tumor appear, despite advanced technologies, which have a major impact on treatment management. We reported two cases with clinical and dermoscopic aspects of cutaneous melanoma, sustained by positive lymphoscintigraphy. The histopathological exams established that the skin tumor was a pigmented basal cell carcinoma. In such difficult cases, the accuracy of diagnosis is certified only by the microscopical examination with clinical, treatment and prognosis changes.
