Melanoma superficial spreading Images

Melanoma, malignant, superficially spreading: Exceptionally large, 8.0x4.0 cm in diameter, regressive, completely asymptomatic malignant melanoma of the SSM type. No bleeding, no oozing. The late visit to the doctor was inexplicable after about 20 years (photo comparisons possible) of growth. The patient carefully clothed the melanoma-bearing area during free exposure to the sun.
