This article simply shows that intradermal nevi on volar surfaces can present with a parallel ridge pattern just like acral melanoma

Abstract
Dermoscopy allows early detection of melanoma also on acral volar skin. The majority of melanocytic nevi on palms and soles may show three major dermoscopic patterns: the parallel-furrow pattern, the lattice-like pattern, and the fibrillar pattern. Melanomas at these sites are characterized by the parallel ridge pattern. We present the case of a 59-year-old woman who had an oval papule of bluish color, measuring 0.6 × 0.9 cm, localized on her left sole, that had been present, unchanged, for more than 10 years. Dermoscopy showed a parallel ridge pattern. The histopathological examination revealed a combined blue nevus. We present this case to underline that on acral volar skin also intradermal nevi, such as combined blue nevi, may dermoscopically exhibit a parallel ridge pattern, simulating melanoma.

It wouldbe nice to see a picture of this lesion. It makes one wonder if it might happen the other way round i.e furrow pattern in melanoma. There's a challenge for you Cliff, find one of those and Ian will do a lot more than 3-putt!
You are so cruel!
