Be mindful of melanoma mimics

Due to the chaotic behaviour of the tissue, melanomas can resemble benign lesions

The presentation of melanoma can break the clinical pattern of other lesions at the same anatomical location by virtue of its size, shape or colour.


However, because the chaotic behaviour of malignant tissue is unpredictable, melanoma can also mimic other lesions.

They will frequently clinically resemble a naevus, solar lentigo, lichen planus-like keratosis or seborrhoeic keratoses.

Because seborrhoeic keratoses are extremely common, it is also not unusual to encounter a collision between them and malignant skin tumours, including squamous cell carcinoma,
