Case 2

What are these skin lesions?

Ephelides or freckles.

What are the clinical features of this disorder?

The ephelis (pl. ephelides) presents as a 1-5mm tan macule that shows up with sun exposure and tends to fade in winter. Histologically the pigment is found within keratinocytes because of increased localised production of melanin by genetically programmed melanocytes. Ephelides are particularly common in fair-skinned and red-haired individuals during childhood and adolescence, and appear mainly on the nose, cheeks, shoulders and upper back. They tend to fade during the winter months and with age. Sunscreens may prevent their appearance.
