GFAP (Glial Fibrillary Acidic Protein) was one of the intermediate filament group and used as an astrocyte marker. The numerous studies about GFAP immunoreactive cell's distribution were investigated for fetus, neonate and aged brains. There are several reports about that GFAP immunoreactive cells were appeared at early fetus and after birth. In cases of mammalian fetus radial glia cells migrated toward pial surface at early stage and revealed GFAP immunoreactivity by the immunostain. But in cases of rodents, they migrated at late gestation or after birth. This study, the GFAP immunoreactive cells' localizations and distribution in the fetuses (the 30 th, 45 th, 60 th, 90 th, 105 th, 120 th of gestation) and neonate mesencephalon of korean native goat were investigated by immunohistoche-mistry (ABC method). The results obtained in this study were summarized as followings; 1. Multipolar astrocytes at 60 days of gestation were found in midbrain, in 90 days of gestation were found in cerebral aqueduct. 2. Radial glial cell presented 60 days of gestation and process of GFAP immunoreaction was to stretch out from ventricular to pia mater and nonpolar immunoreactive cell was transformed to bipolar, monopolar and multipolar immunoreactive cell. 3. The number of GFAP immunoreactive cells of field were gradually decreased from 90 days of gestation till 105 days of gestation. But in 120 days of gestation and newborn were slightly increased. 4. Immunoreactivity of GFAP immunoreactive cells were gradually decreased from 95 days of gestation till 120 days of gestatioin. These results were suggested that radial glial cell of midbrain developed very earlier than that of cerebral aqueduct. However, cerebral aqueduct developed lately than that of midbrain, but faster developing than other.

Lymphangiomatosis is a very rare and slow-growing benign tumor generally accepted to be the result of a congenital malformation of the lymphatic system. It is most commonly found in the neck, axilla and less commonly retroperitoneum, mediastinum, mesentery, omentum, pelvis, bone, skin, scrotum, and spleen. We present a patient who had systemic lymphangiomatosis with splenic involvement. She was presented with the cystic neck mass suspected to be a cystic hygroma during the first decade. She complained of the mass on left upper quadrant of abdomen at the age of 28. Under full investigations, we had diagnosed the lymphangiomatosis involving spleen and right adrenal gland, and splenectomy was done. We present a case of systemic lymphangiomatosis with emphasis on diagnosis, management, and prognosis.
