Pigmented skin lesions analysis

The observation of pigmented skin lesions through dermoscopy is the more accurate way to early the melanoma.

Although the identification of this type of neoplasy is often hampered by its confounding clinical features, the dermatologist's trained eye is able to orient the differential diagnosis of the lesion.

The dermoscopic exam focuses on the global structural organization, the morphology, the pigmentation of the lesion and the presence of vascular structures.

The diagnosis of melanoma is based on the analysis of well defined features, together with the patient anamnesis.

The distincion between a baenign lesion and a tumoral melanocitary proliferation is hampered by the current difficulty in establishing a clear distinction.

Aproximately 40-50% of melanomas originate from pigmented naevi and, because of the significant morphological overlapping of these two types of lesions, the early recognition of the tumor is often missed. As a consequenc numerous of unpleasant surgical excision are performed on baenign naevi.

Malignant melanomas are extremely various in color, size and shape, with a different tendency to invade other tissues and metastize.

This neoplasy can rapidly spread and result in a lethal condition in a few months from its identification. In light of these evidences it is clear how the immediate detection is essential.
