To evaluate the morphogenesis of the human thyroid, a histologic study was made based on 100 normal thyroids of human embryos and fetuses ranging in age from 4 to 42 weeks of gestation. The embryos were serially sectioned and fetuses were examinated as an individual organ. 1) The first sign of thyroid primordium was the spherical proliferation of median ventral pharyngeal wall at the 4th week of development. 2) At the 6th week of gestation, the thyroid differentiated into two lobes that were connected by an isthmus, and was on the way of migration to the definite position from the foramen cecum. 3) The developing thyroid consisted of two cell cords, solid nests or interconnecting complex pattern until 14th week of gestation, when the entire portion of thyroid was replaced by follicles of variable size. 4) At the 9th week, the first follicle was recognizable at the periphery of the gland. 5) At the 14th week, follicles were partly filled with faintly eosinophilic colloid. 6) After the 18th week of gestation, lobulation of the thyroid parenchyme was a prominent feature. 7) After the 24th week, large follicles with rich colloid content are distributed through both superificial and deep portions. And after the 34th week, maturation reached the general pattern of adult thyroid. 8) The ability of thyroglobulin synthesis which was confirmed by PAP method, was first recognized at the 10th week of gestation.

Aplasia cutis congenita is a rare disorder characterized by localized or generalized absence of skin at birth. Group 4 in Friden's classification, which is associated with embryologic malformations including myelomeningocele, encephalomeningocele, omphalocele, gastroschisis. The authors have experienced a case of aplasia cutis congenita of right frontal scalp associated with bony defect, forming encephalocele in a newborn. We reported this case with brief review of literatures.

PURPOSE: With the process of neoangiogenesis being linked to the growth and metastasis of various tumors, anticancer therapeutics with a basis in the suppression of neoangiogenesis has recently been receiving attention. In this study, we tried to clarify the immunoreactivities of vascular endothelial growth factor (VEGF), major angiogenic inducer and thrombospondin-1 (TSP-1), major angiogenic inhibitor in human Wilms' tumor and its clinicopathological significance. MATERAILS AND METHODS: Utilizing immunohistochemical staining, we assessed the immunoreactivities of VEGF and TSP-1 in archival tissues of 29 Wilms' tumors and 25 normal kidneys. Also, we assessed the relationship between expression of each factor and clinicopathological parameters in 29 cases of Wilms' tumors. RESULTS: Immunoreactivities of VEGF and TSP-1 were detected mainly in the cytoplasm of the tubular cells in normal kidneys. In Wilms' tumors, whereas VEGF was detected in the cytoplasm of the tumor cells and peritumoral stromal tissues, but TSP-1 only in the peritumoral stromal tissues. Immunohistochemical expression patterns of each factor were divided into two groups according to the area of immunoreactivity (negative:<10%, positive: > OR =10%). VEGF immunoreactivity was detected in 25 (100%) normal kidneys and in 20 (69%) Wilms' tumors. However, TSP-1 immunoreactivity was detected in 24 (97%) normal kidneys and in 3 (10%) Wilms' tumors. Therefore, although no significant difference was observed between the expressions of VEGF and TSP-1 in normal kidney, the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors. A relatively higher rate of positive expression of TSP-1 was observed in the patients with no demonstrable lymph node metastasis. Also, as for the VEGF, maximal diameter of the tumor was larger in the positive expression group. However, it proved otherwise for TSP-1 as the negative expression group demonstrated tumors with larger maximal diameters. CONCLUSIONS: Our study demonstrated that the TSP-1 immunoreactivity was significantly lower than VEGF immunoreactivity in Wilms' tumors, and disease progression has a tendency to be found in the VEGF-positive cases and TSP-1 negative cases. We suggest that the growth and metastasis of Wilms' tumor may be influenced mainly by TSP-1 decrease rather than VEGF increase.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.
