[Native favus in Poitou. About 3 cases (author's transl)].

Three cases of tinea favus of pityriasic aspect and without a "scutulum" sign are diagnosed in a small town of "Poitou" region. They correspond to an autochtonal focus. The various enquiries show that favus has become rare in France but the local focus as are still active, since 43 p. 100 of recorded favus are of local origin.
