The article presents the announcement of a joint meeting of the Society for Investigative Dermatology and the European Society for Dermatological Research from May 17 through May 19, 1972. The purpose of this meeting will be to serve as a forum for the presentation of original dermatological research papers. Twelve minutes will be allotted per paper. All presentations must be in English. Simultaneous translation will not be provided. The program will be selected by a joint program committee of the two sponsoring Societies. The article also announces that the Third World Congress of the International Society of Tropical Dermatology will be held in Sao Paulo, Brazil, on September 13-18, 1974.

Within solid neoplasms. the population of tumor cells and the population of capillary endothelial cells constitute a highly integrated ecosystem. Tumor cells release an endothelial mitogen. Tumor-Angiogenesis-Factor (T.A.F.) which continually stimulates new capillaries to grow into the tumor. When T.A.F. is blocked, neovascularization is prevented and tumor nodules stop expanding at a diameter less than 2.5 mm. They enter a dormant phase because they are forced to live by simple diffusion of nutrients and wastes. Thus "anti-angiogenesis can force a population of tumor cells to become dormant at a tiny diameter. In this paper an analogy is drawn between tumor angiogenesis and the angiogenesis which accompanies psoriasis. if the relationship between psoriatic epithelium and its capillary endothelium turns out to be similar to the integration of capillaries by solid tumors, then "anti-angiogenesis' may eventually become a useful therapeutic approach in psoriasis.

The Subsection of Dermatology of the Western Section of the American Federation for Clinical Research will meet as a part of the annual joint meeting of the Western Section of the American Federation for Clinical Research, the Western Society for Pediatric Research and the Western Association of Physicians, in Carmel, California, from January 31 through February 3, 1973. This Subsection of Dermatology is recognized and supported by the Society for Investigative Dermatology as a regional meeting of the Society. Papers for presentation at this meeting are hereby solicited. Dermatologists who wish to present a paper at this meeting but who are not members of one of the three parent organizations can without difficulty usually find a member to sponsor their presentation.

Applications are being invited for scientific papers to be read before the Section on Dermatology of the American Medical Association meeting on June 20-24, 1971 at Atlantic City, New Jersey. Moreover, there will be two meetings of the Society for Investigative Dermatology Inc. in the year 1971. The spring meeting will be on May 1, 1971 and the thirty-second annual meeting will be held on June 18-20, 1971. The formation of the European Society for Dermatological Research has also been announced. The objective of the society is the promotion of research related to skin and its disease through the application of methods of natural sciences.
