Abstract
A 17-month-old girl presented with a medium-sized congenital melanocytic naevus on the dorsum of the right foot. Histological examination of the excised specimen revealed a malignant melanoma (Breslow thickness 3.2 mm, Clark level IV) in a compound naevus. Wider excision with a 20-mm margin, according to protocol, followed. No metastases were discovered on complete systemic investigation. The patient remains tumour-free, 5 years later. The clinical dilemma posed by the medium-sized melanocytic naevus, in relation to small and large congenital melanocytic naevi is discussed.
