Patient and Clinical Characteristics.

Melanoma Subtypes and Localization Cutaneous melanoma was the most common subtype (81.1%, n=73), followed by ocular (10.0%, n=9) and mucosal melanoma (8.9%, n=8). In five patients, the primary tumor site could not be identified. Nodular melanoma was the most prevalent histological subtype (46.7%, n=28), followed by lentigo maligna (21.7%, n=13), superficial spreading melanoma (13.3%, n=8) and acral lentiginous melanoma (13.3%, n=8). Information on histological subtype was missing in 35 cases. The extremities were the most frequent tumor location (33.7%, n=32), with the lower limbs accounting for 71.8% of these cases, followed by the head and neck region (22.1%) and the trunk (9.5%).
