Phacomatosis cesioflammea: first case report from India.

Phacomatosis cesioflammea is a rare condition defined by the simultaneous presence of both vascular and pigmentary nevus in the same patient. We report a case of a 4-year-old Indian female child who presented with diffuse dermal melanosis on the upper shoulders, upper anterior chest and lower back and extending to involve both sides of the arms and forearms, generalized port-wine stain on the back, shoulders and both upper limbs with sparing of the right palm. At places, the two types of lesions were superimposed on each other and were also present discretely on the back, but in close proximity to each other. There was the presence of melanosis bulbi on the right side of the eye. She was otherwise normal. She was clinically diagnosed as a case of phacomatosis pigmentovascularis cesioflammea. The nonallelic twin spotting phenomenon has been proposed in the pathogenesis of this disorder.
