Unilateral keratoderma in a mother and her son.
BACKGROUND
Keratoderma is a group of conditions characterized by hyperkeratosis affecting the skin on the soles of the feet and palms of the hands bilaterally. The classification of keratodermas depends on whether it is inherited or acquired and on its clinical features, including diffuse or focal involvement of the skin and the morphology of lesions present.


METHODS
We describe the rare case of a 54-year-old female who presented with a nearly 40-year history of punctate keratoderma on her right palm and sole. History taking revealed that her biologic son also has unilateral left-sided keratoderma. The clinical presentation of unilateral keratoderma has been reported only four times in the literature.
