During the past ten years numerous new findings have been documented in
the field of gynecological pathology, especially in respect of
neoplasms. These findings have been generated by the application of
recently developed techniques of immunology and molecular biology.
However, clinicopathologic examinations- are still an absolute
requirement for the morphologic evaluation of neoplasms, including
gynecological tumors. The International Society of Gynecological
Pathologists (ISGYP) has contributed greatly to the progress within
gynecological pathology. The ISGYP Nomenclature Committee has promoted
the International Histological Classification of Gynecological Tumors
under the auspices of the W orid Health Organization. A new edition of
the classification of tumors and tumor-like conditions of trophoblastic
disease, uterine corpus, cervix, vagina, and vulva is currently in
press. A second volume covering the ovaries, fallopian tubes, broad
ligament, and female peritoneum will be published later. Organization of
scientific symposia and seminars has also been an important activity of
the ISGYP. The present editor organized and chaired a symposium entitled
"Recent Progress in Diagnostic Pathology of Gynecological Tumors" held
in Sendai, Japan on 11 April 1986 in close cooperation with Prof. T.
Okagaki, University of Minnesota Medical School, and under the joint
auspices ofthe ISGYP and the Japanese Society of Pathology. The
following topics were discussed at this symposium: - Immunocytochemistry
