Unilateral Darier's disease.

A 60-year old house-wife presented with mildly pruritic, over crusted, greasy, follicular and non-follicular papules over the forehead, retroauricular region and abdomen on the right side. There were numerous discrete hypopigmented macules scattered over the mammary region, abdomen, thigh and leg on the right side. Histopathological study of one of the papules over the forearems showed features of acrokeratosis verruciformis of Hopf.
