Hallermann's Syndrome*

The Sertoli-Leydig cell tumor is a gonadal tumor of sex-cord stromal type, similar to that seen in of the various phases of testicular development in the male. This tumor is exceedingly rare, accounting for only 0.1% to 0.5% of all primary ovarian neoplasms. It occurs predominantly in the second and third decades(mean age about 25 years), less than 10% after menopause. We investigated a case of poorly differentiated Sertoli-Leydig cell tumor of right ovary, occured in a 76-year-old woman. Grossly, the tumor measured 2, 100 gm in weight and 25 x 19 x 8 cm in dimensions. The outer surface was smooth and glistening without rupture of the capsule. Cut sections revealed a multilobulated brown solid mass with multiple cystic change. Microscopically, it showed the typical findings o a Sertoli-Leydig cell tumor. The characteristic feature is hemangiopericytoma paftem of sarcomatoid spindle cells. Therefore, we present it with a brief review of the literature.

Gestational trophoblastic tumor is one of the curable disease, but metastatic trophoblastic tumor still shows high mortality rate because of resistance to the chemotherapy. Choriocarcinoma may occur after an any type of human pregnancy. The incidence of choriocarcinoma following term pregnancy is very uncommon, and such tumor appears to follow a more aggressive course with more extensive metastatic spread and is less responsive to chemotherapy resulting in a poorer prognosis. Choriocarcinoma presenting as postpartum hemorrhage, and spontaneous tumor perforation with intra-abdominal hemorrhage is even rarer, requiring emergency laparotomy. We had experienced one case of metastatic choriocarcinoma following term pregnancy that required emergency total abdominal hysterectomy due to uterine perforation and hemorrhage. So, we report this case with brief review of literatures.

During the three the coronavirus disease 2019 (COVID-19) surges in South Korea, there was a shortage of hospital beds for COVID-19 patients, and as a result, there were cases of death while waiting for hospitalization. To minimize the risk of death and to allow those confirmed with COVID-19 to safely wait for hospitalization at home, the local government of Gyeonggido in South Korea developed a novel home management system (HMS). The HMS team, comprised of doctors and nurses, was organized to operate HMS. HMS provided a two-way channel for the taskforce and patients to monitor the severity of patient's condition and to provide healthcare counseling as needed. In addition, the HMS team cooperated with a triage/bed assignment team to expedite the response in case of an emergency, and managed a database of severity for real-time monitoring of patients. The HMS became operational for the first time in August 2020, initially managing only 181 patients; it currently manages a total of 3,707 patients. The HMS supplemented the government's COVID-19 confirmed case management framework by managing patients waiting at home for hospitalization due to lack of hospital and residential treatment center beds. HMS also could contribute a sense of psychological stability in patients and prevented the situation from worsening by efficient management of hospital beds and reduction of workloads on public healthcare centers. To stabilize and improve the management of COVID-19 confirmed cases, governments should organically develop self-treatment and HMS, and implement a decisive division of roles within the local governments.

The authors studied the strabiEmus of 50 cases in children under six years of age. A total of 50 cases were screened in out patient department from April 1972 to July 1973. The results are as followings: Among them, 28 cases of exotropia, 18 cases of exotropia and 4 cases of hypertropia were observed. Generally, there were more female than male. According to the refractive status, there were more hypertropia among esotropia and more myopia among exotropia. There were only 3 cases those visual acuity were below 0.1 and the remainder were above 0.1. According to the age, there were 11 cases under the 2 yrs of age, 15 cases in the age 3 yrs to 4 yrs and 20 cases over 6 yrs. The onset of 36 cases were so incidious that were unknown and those of 8 cases were gradual. The strabismus were markedly detected under the 1 year of age (26 cases) and 31 cases were alternating type and 15 cases were monocular. And it \vas interesting fact that 19 cases were first child.

Pseudomyxoma peritonei is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Pseudomyxoma peritonei is most commonly associated with mucinous tumors of the ovary and appendix. When two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. Many studies concluded that most cases in which both the appendix and ovary were involved were primary appendiceal tumor with secondary involvement of the ovary, but we have experienced one case of pseudomyxoma peritonei originated from independent primary borderline mucinous tumors of the ovary and appendix. So we report this case with the brief review of literatures

PURPOSE: To evaluate the CT appearance of renal cell carcinoma and to correlate it with nuclear grading andcell type. MATERIALS AND METHODS: The size, outer margin and heterogeneity of inner texture of renal cell carcinomas in 86 patients were evaluated on CT scan and were correlated with nuclear grade and cell type. RESULTS: Tumors less than 5cm were of low grade in 28 of 31 patients, while those larger than 5cm were of low grade in 28 of 55 patients. The lesions which showed no or round protrusion with a sharp margin were of low grade in 26 of 28 patients, while those which showed an undulated or indistinct margin were of low grade in 30 of 58 patients. Lesions which showed a homogeneous solid appearance, focal low densities, or mostly cystic changes were of low grade in 23 of 26 patients, while those which showed multiple or confluent low densites were low grade in 33 of 60 patients. There was a significant difference in the distribution of nuclear grading between the groups. Differences in CT apperance according to cell type were not found. CONCLUSION: Differences in less than 5cm showing no or round protrusion with a sharp margin, homogeneous inner texture with solid appearance, and heterogeneous inner texture with cystic appearance or focal low densities on CT scan were thought to be the findings suggesting low nuclear grading.
