Abstract
The authors present new cases of malignant melanoma seen at the Skin Cancer Clinic of the University Hospital in Martin in the year 2017. There have been 112 new cases of malignant melanoma, 66 in men and 46 in women, diagnosed in 2017. We have recorded a occurence of two melanomas in one person in 3 patients, two men and one women. One patient had metastatic melanoma found in lymph nodes without corresponding skin lesions. The most common tumor body localisation in both men and women was on the back (51 melanomas, 45 %). In women, the most common localisation was upper extremities (13 melanomas, 29 %), followed by lower extremities and the back at the same rate (11 melanomas, 24 %). In men, the most common localisation was on the back (40 melanomas, 60 %). Histologically, the most common type was superficial spreading malignant melanoma (50 melanomas), the second most common was non specific type of malignant melanoma (19 melanomas). The majority of cases were low risk lesions with histological Breslow thickness in the range from 0,1 mm to 1 mm (47 melanomas). High risk lesions with histological Breslow thickness more than 4 mm were the second most common type (24 melanomas).
