                     XANTHO-ERYTHRODERMIA PERSTANS.
                        By H. RADCLIFFE-CROCKER.


The above provisional clinical title was suggested to me by my coadjutor
at University College Hospital, Mr. George Pernet, for a well-defined
affection of the skin, of which I have met with ten instances during the
last three years, all but one of them in private practice. I am not
aware that the disease in question has been described before, unless it
can be brought under Brocq’s “erythrodermies pityriasiques en plaques
disseminées,” with which it will be closely compared when the cases
themselves have been considered.

A case which I showed at the Dermatological Society of London in
October, 1904, when Drs. Hallopeau, Gastou, Jacquet and Pautrier were
present, was not regarded by them as a case of Brocq’s disease, with
which they were presumably familiar, but as an entirely new affection in
their experience.

The following description is drawn up from nine of the cases, all males,
which, in the main features, closely resemble each other. The remaining
case, a lady, had some important differences which will be discussed
later.

So far, all the cases have been adults, though some of them were young.
The lesions are evolved in patches
