Under the title of alopecia triangularis congenitalis Sabouraud1 described a type of congenital alopecia occurring on the temples. It is characterized by a unilateral or bilateral patch of complete alopecia of triangular form. Its base is directed toward the forehead, and its longest diameter is 1 to 1½ inches (2.5 to 4 cm.) long. No treatment is of avail.

The condition is extremely rare. Sabouraud saw it only 5 or 6 times. Galewsky2 observed 1 case, in which it was bilateral. No other case has ever been reported. In English literature the only reference to this condition was made by McCarthy.3

Sabouraud stated that this anomaly should be known so that it will not be mistaken for alopecia areata and treated unnecessarily.
