Frontal Fibrosing Alopecia and Ulerythema Ophryogenes as Two Entities That Can Transition One Into Another

The authors described two cases of progressive hair loss in the frontoparietal scalp area and total eyebrow loss in a mother and daughter, diagnosed with scarring alopecia. The symptoms were characteristic of frontal fibrosing alopecia, typically seen in postmenopausal women, and ulerythema ophryogenes, a keratosis follicular disorder appearing in early infancy with familial occurrence. They hypothesized that these two diseases share many similarities and could potentially evolve from one into the other.
