The child’s parents relate to the brothers having the scaling on and off since the children were about 4 or 5 years old. Flare-ups would often be exacerbated during the summer and winter months. In the summer, the children would often swim in the family pool and develop severe regions of itching to both extremities. It was particularly severe in areas of skin folds, particularly to the anterior ankle and back of the knees. In the winter months, the skin would not stay hydrated enough, and the skin would typically get very itchy and secondarily infected from scratching. This would leave the skin with crusts and lichenified regions of skin after scratching.

The children would often have areas of skin that would not tan or pigment after these flare-ups. (Fig. 3)
