Abstract
In the past, malignant melanoma (MM) is a diagnosis of unheard in children, but nowadays MM is a very rare malignancy in children. Its diagnosis requires careful interpretation of the pathological diagnostic criteria with clinical correlation of the findings. In this study, the authors are presenting a pigmented lesion in a 12-month-old girl, which was present since her birth with increase in size and shape. The authors discussed the difficulty that confronted them in making a diagnosis of MM and the differential diagnosis.
