RT Journal A1 THALHIMER W T1 LImitation of roentgenotherapy of surface epitheliomas JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1919 FD April 26 VO 72 IS 17 SP 1218 OP 1218 DO 10.1001/jama.1919.02610170020008 UL http://dx.doi.org/10.1001/jama.1919.02610170020008 AB In this case, an epithelioma of the skin of the dorsum of the hand was treated by the roentgen ray, and after a resection of a resulting ulcer, a local cure occurred. Subsequently to this, a large tumor appeared in the axilla which proved to be a metastatic squamous cell carcinoma. It is evident that in cases of this nature, if roentgenotherapy is resorted to, it should not be confined to the superficial tumor, but the regional lymph nodes along the path of lymphatic drainage also should be thoroughly treated.

This rule is recognized by roentgenotherapeutists in treatment of epithelioma of the lip, in which they especially caution that the neighboring lymph nodes should also be treated. It would seem that this rule is not so well appreciated in the treatment of epitheliomas of the skin of the extremities. The case here reported
