3.A Case of Ocular Neurofibromatosis.
Korean Journal of Pathology 1987;21(1):62-65
Neurofibromatosis is one of the neurocristopathies that involve many system or tissues forming various types of lesion. Almost every tissue or organ can be involved by this disease. However, the eyeball itself is very rarely affected by this process. The findings seen in our case indicate the diversity of lesions in neurofibromatosis, and also suggest hamartomatous nature. Heterotopic ganglion cells and glial cells in uveal tract are not easily understood. We reported here a case of intra-occular neurofibromatosis with its characteristic involvement of the uveal tract, in a 21 year old female. Her ocular symptoms began at her age of 11 as poor vision and were slowly progressive together with multiple facial neurofibromas. The involved left eyeball showed many ganglioneuroglial cell nests in iris, ciliary body and retina. Minute plexiform neurofibromas were also seen in small nerve twigs around the eyeball.

4.Congenital Bronchopulmonary Foregut Malformation: Analysis of the surgical and autopsy cases.
Korean Journal of Pathology 1993;27(5):459-467
Because early embryonic development of the tracheobronchial tree and foregut are closely associated, there is a wide spectrum of congenital anomalies involving either one or both organ systems. We analysed a total of 89 surgical and autopsy cases that are assumed to belong to congenital bronchopulmonary foregut malformation from the files of Seoul National University Hospital and Children's Hospital during the periord of 1961~1990. We also reviewed the serial sections of the embryos and fetuses from 3 weeks to fifteen weeks fertilization age for the observation of tracheobronchial and esophageal trees. Intralobar sequestrations(25 cases) and extralobar pulmonary sequestrations(4 cases) with patent, involuted-partial or complete-communication with the alimentary tract, tracheoesophageal fistula(30 cases) with or without esophageal atresia, esophageal atresia, esophageal stenosis due to tracheobroncheal remnant(4 cases), foregut duplication cysts(3 cases), esophageal or gastric diverticulum(1 cases), and bronchogenic cysts(22 cases) are included in this analysis(Table 1). Through this study, we confirmed the unifying concept of "bronchopulmonary forgut malformations". We believe a common embryologic pathogenesis leads to the formation of a previously described spectrum of malformations.
5.Parapelvic Renal Cyst (Pericalyceal Lymphangiectasis): A case report.
Korean Journal of Pathology 1994;28(2):210-212
Parapelvic renal cyst, also designated as pericalyceal lymphangiectasis, is an unusual lesion that is usually brought to light during surgery for ureteropelvic junction obstruction or recurrent pyelonephritis. Grossly, the renal pelvis is enveloped by a multilocular cystic mass filled with clear fluid. This lesion is confined to the peripelvic tissues and does not extend into the parenchyma, which, however, may show the effects of hydronephrosis or pyelonephritis. A 50-year-old man presented with hydronephrosis. An ultrasonography revealed hydronephro-sis of the left kidney. Intravenous pyelography and DMSA ("Tc-Dimercaptosuccinic acid) scan showed nonfunctioning kidney of the same side. Simple left nephrectomy was done. The renal pelvis was mildly dilated and a cyst was found buldging into the renal pelvis. The content was watery clear and the cyst was not connected to the renal pelvis or calyces. The cyst was round unilocular and lined by attenuated single layer of endothelial cells. The endothelial cells showed no reactivity to factor-VIII related antigen. With these findings, we concluded that this cystic lesion is basically lymphatic cyst and hydronephrosis was caused by the compression of pelvic out-flow of the kidney.

A study was performed to observe the sequential morphological change of the human placental barrier by means of light microscopy, immunohistochemistry, scanning electron microscopy and transmission electron microscopy. The examined placentas ranged in age from 4 weeks gestation to the full-term(40 weeks). Sixty seven placental specimens were obtained immediately after delivery. With the progression of gestation, the microvilli on the surface of syncytinum tended to be fewer, shorter and blunter. The syncytiotrophoblasts were getting thinner with formation of vasculo-syncytial membrane. The cytotrophoblasts formed a continuous layer which progressively disappeared but still present in the mature villi. In view of presence of intermediate cells and remnant of desmosomes, the cytotrophoblasts appeared to form the syncytiotrophoblasts. In early pregnancy, capillary formation took place by the aggregation and differentiation of the proliferation and aggregation of endothelial cells and pericytes. Myofibroblasts in villous stroma were examined by desmin immunohistochemical staining, and detected from 19 weeks to the full-term. During last period of pregancy definitive smooth muscle cells could be demonstrated, suggesting that the presence of myofibroblasts or smooth muscle cells are closely related to the placental maturity. Scanning electron microscopy of the early placenta showed numerous syncytial sprouts representing stages in the formation of new villi, but in the late period of gestation syncytial sprouts were diminished. It is concluded that the syncytiotrophoblast is originated from the cytotrophoblast in early pregnancy as the placental barrier is formulated. Moreover, myofibroblasts and smooth muscle cells in villous stroma play important role in placental maturation.

Phycomycosis is an uncommon opportunistic fungal infection, involving several organs, such as brain, lungs, gastrointestinal tract and skin. Invasion of joint cavity by phycomycetes, however, has never been reported. We report a case of 33-year-old male who had had prehallux with congenital equinovarus and underwent correction operation on the right ankle joint. There after, joint pain and edema had developed on that site. He received reoperation and underwent excisional biopsy from there. Operation showed hypertrophied yellowish synovium. On microscopic examination, the tissue showed several foci of fibrinoid necrosis and suppurative and granulomatuous inflammation. Periodic acid Schiff stain demonstrated broad. Aseptate hyphae that were wrinkled and folded.
