RESUMO
A 13-year-old Hispanic boy with no significant medical etymology presented with a chief complaint of widespread brown macules and patches. He had a large and evenly pigmented brown patch, with a centrally located 2.2 cm × 1.2 cm soft and darkly pigmented plaque, which became more apparent with tension applied to the surrounding skin (Figure 1). The patient's mother stated that the plaque was present since birth and had increased in size over time. The clinical differential diagnoses included a congenital melanocytic nevus (CMN), a large café au lait macule (CALM), and a Becker's nevus with a congenital smooth muscle hamartoma.

Congenital onychodysplasia, or Iso-Kikuchi syndrome, is classically defined as a congenital nail abnormality of one or both index fingers that is often associated with a bone abnormality in the affected finger. We report an unusual case of a 6-year-old girl who presented with an S-shaped, bifid nail of the left ring finger that had been present since birth. X-ray findings were used to confirm a diagnosis of congenital onychodysplasia of the ring finger.
