Mucinous Cystadenoma of the Testis: A Case Report with Immunohistochemical Findings
김길향,문경철,권도희,나희영,김세희 대한병리학회 2017 Journal of Pathology and Translational Medicine Vol.51 No.2
Mucinous cystadenoma of the testis is a very rare tumor. Herein, we report a case of mucinous cystadenoma arising in the testis of a 61-year-old man, along with a literature review. Computed tomography showed a 2.5-cm-sized poorly enhancing cystic mass. Grossly, the tumor was a unilocular cystic mass filled with mucinous material and confined to the testicular parenchyma. Histologically, the cyst had a fibrotic wall lined by mucinous columnar epithelium without atypia. Immunohistochemical staining was positive for cytokeratin 20 and CDX2, as well as focally positive for cytokeratin 7. The pathologic diagnosis was mucinous cystadenoma.

Background: Human epidermal growth factor receptor 2 (HER2) is one of the known oncogenes in urothelial carcinoma. However, the association between HER2 and the prognosis of upper urinary tract urothelial carcinoma (UUTUC) has not yet been fully clarified. The aim of this study was to evaluate HER2 expression using the United States Food and Drug Administration (FDA) criteria and American Society of Clinical Oncology/College of American Pathologists (ASCO/CAP) criteria and compare their prognostic significance in UUTUC. Methods: HER2 expression was evaluated in 144 cases of UUTUC by immunohistochemistry (IHC) using tissue microarrays. We separately analyzed HER2 expression using the FDA and ASCO/CAP criteria. The IHC results were categorized into low (0, 1+) and high (2+, 3+) groups. Results: Using the FDA criteria, 94 cases were negative, 38 cases were 1+, nine cases were 2+, and three cases were 3+. Using the ASCO/CAP criteria, 94 cases were negative, 34 cases were 1+, 13 cases were 2+, and three cases were 3+. Four cases showing 2+ according to the ASCO/CAP criteria were reclassified as 1+ by the FDA criteria. High HER2 expression by both the FDA criteria and ASCO/CAP criteria was significantly associated with International Society of Urological Pathology high grade (p = .001 and p < .001). The high HER2 expression group classified with the FDA criteria showed significantly shorter cancer-specific survival (p = .004), but the HER2 high and low expression groups classified with the ASCO/CAP criteria did not show significant differences (p = .161) in cancer-specific survival. Conclusions: HER2 high expression groups were significantly associated with shorter cancer-specific survival, and our study revealed that the FDA criteria are more suitable for determining HER2 expression in UUTUC.

Multiple Eruptive Epithelioid Hemangiomas on the Right Upper Extremity in an Asian Man
김길향,김진철,강석영,김혜원,박천욱,정보영 대한피부과학회 2023 Annals of Dermatology Vol.35 No.-
Epithelioid hemangioma is a rare benign vascular neoplasm. Recently, the term “multiple eruptive epithelioid hemangioma” has been proposed for epithelioid hemangioma with dis- tinct features. It is different from usual epithelioid hemangioma because of the multifocal distributions in various body regions with an eruptive onset. In addition, the histopathology of multiple eruptive epithelioid hemangioma shows increased cellular proliferation, mitosis, and nuclear pleomorphism and positive findings for FOS-B compared to classic epithelioid hemangioma. Herein, we report the case of a 59-year-old man with unusual manifestations suitable for multiple eruptive epithelioid hemangioma. He had multiple erythematous to purple-red dome-shaped nodules on the right hand, arm, and shoulder. The initial lesion was a solitary erythematous nodule on the right hand that abruptly extended to the right arm and shoulder. Microscopically, the tumor was a well-demarcated dermal nodule and showed capillary sized vascular structures. Vascular structures had epithelioid endothelial cells with abundant eosinophilic cytoplasm and vesicular nuclei. The tumor cells showed mild nuclear pleomorphism and a few mitosis and feature of resembling cobble stone was observed. In immunohistochemistry, CD31 and CD34 were positive in the endothelial cells. The endothelial cells showed nuclear positivity in FOS-B. Based on the clinical and histo- pathological findings, the final diagnosis was multiple eruptive epithelioid hemangiomas. This is the first report of multiple eruptive epithelioid hemangiomas in an Asian man after the term had been introduced.

부교감신경차단제 및 항 Histamine 제의 배합투여가 Salicylamide 의 진통작용에 미치는 효과에 관한 연구
우종학,김신근,김길향,김재완 한국약제학회 1971 Journal of Pharmaceutical Investigation Vol.1 No.1
Comparative studies were made on the analgesic effect of salicylamide, used individually and combined with parasympatholytics (propantheline and atropine) and antihistaminics (tripelennamine, diphenhydramine) as regards the analgesic effect (in thermal contact method) were examined by its oral administration with each combined drug to mouse (three assumption cross-over test), and the following effects were found. 1. The increasing order of the parasympatholytics to the analgesic effect of salicylamide is as follows: propantheline>atropine. 2. The increasing order of the antihistaminics to the analgesic effect of salicylamide is as follows: chlorpheniramine>diphenhdramine>tripelennamine. In the ratio "1 : 1" salicylamide to parasympatholytics and antihistaminics, the analgesic effect of salicylamide was more increase than the other ratio in this study.
