A 24-years old woman presented with asymptomatic, raised, black, skin lesions on the sole of her right foot since birth. Examination revealed three, hyperpigmented nodulo-plaques on the right foot distal plantar aspect proximal to the second toe. [Figure 1a]. Dermoscopy showed cerebriform appearance with sulci and gyri [Figure 1b]. Histopathology showed basaloid naevus cells with melanin in the upper dermis and naevus cells interspersed within the dense collagen bundles and extended around the adnexal structures. A diagnosis of cerebriform congenital melanocytic naevus (CMN) was made, which is a rare morphological variant of CMN reported previously on the scalp. The index case is the first report of cerebriform CMN on the sole of the foot.
- Three well-defined hyperpigmented plaques on the sole of the right foot.
- Dermoscopy (Dermlite, 10x, polarised mode) showing prominent sulci and gyri, giving a cerebriform appearance of the naevus with accentuation of pigmentation in the sulci.
