Clinical investigation of the novel iron‐chelating agent, CP94, to enhance topical photodynamic therapy of nodular basal cell carcinoma: when statistics make a difference

licular ostia. The diagnosis of cicatricial alopecia was suggested by scalp dermoscopy that showed diminished hair follicle density with loss of follicular ostia and absence of signs of inflammation or traction. The absence of yellow dots or perifollicular keratosis and erythema excluded alopecia areata and frontal fibrosing alopecia. Our series confirms Goldberg’s opinion that CMA can occur in the absence of traction and points out the importance of dermoscopy in the diagnosis of hair disorders. This noninvasive technique allows immediate differential diagnosis between CMA and other diseases affecting the scalp margin, such as alopecia areata and frontal fibrosing alopecia.
