Case of Keratoma Senile.

THIS woman is aged 62, and hyperkeratosis is by no means uncommon at her age. She has, however, suffered from the condition for the last fifteen years, and the "warts and spots" have always been worse in the spring and summer months. There are keratomata, and sessile papillomata on the face and backs of the hands. Pigmented macules and small atrophic spots with loss of elastic tissue are also to be noted. Identical lesions are met with in xerodermia pigmentosa, a condition which occurs in young children, and is frequently fatal before the age of 21 owing to the formation of epitheliomata, especially in areas exposed to sunlight. In this patient's case it will be noted that the degenerative changes are particularly active on the uncovered parts, and Dubreuilh was the first to point out that there is considerable analogy between the two types of cases. The family history of this patient is interesting and highly significant. Her father had similar "spots" on his face and hands. Ultimately he died of cancer of the bladder. One sister died of cancer of the breast another of cancer of the breast after an operation. The treatment of the condition is not satisfactory, as both warts and papillomata are constantly recurring. As in xerodermia pigmentosa the most reliable agent is the X-ray. The growths will also yield to C02 snow. For purposes of demonstration I selected the right side of the faceformerly worse than the left side-for X-ray therapy. She has had only two exposures of X-rays of one-third of a Sabouraud-Noiree pastille each, through I mm. of aluminium plate. It will be seen that the right side has now fewer lesions than the left. In connexion with radiotherapy it must be emphasized that lesions very similar or even indistinguishable from those in this case can be actually produced by prolonged and repeated, or unshielded exposures to the X-rays. This close resemblance is responsible for the fact that many dermatologists prefer the use of C02 snow for such cases. Dr. Norman Paul, of Sydney, in his recent admirable little text-book on the cutaneous cancers, advocates in addition the use of radium.
