Adrenocortical tumors are very rare in children and the clinical course is not clearly understood. The aim of this study is to review the clinical characteristics and courses of pediatric adrenocortical tumors. The medical records of patients who underwent surgery for primary adrenal tumor at the Department of Surgery, Seoul National University hospital, from Jan. 1986 to Feb. 2006 were reviewed. There were 10 adrenocortical tumor patients; 5 had adrenocortical adenoma and 5 adrenocortical carcinoma. All of the adrenocortical adenomas presented as functioning tumors, i.e., Cushing syndrome or virilization. However, only 2 patients had functioning adrenocortical carcinoma. Median size of adenoma was 5 (3.3-6) cm, and carcinoma 12.5 (6.5-13) cm. Adenomas were smaller than 6 cm and carcinomas were larger than 6.5 cm. Surgical resection alone cured all adrenocortical adenoma patients, and they were all alive without recurrence. Three of 5 adrenocortical carcinoma patients died of tumor recurrence despite radical surgery and chemotherapy. There were 2 long-term survivals for adrenocortical carcinoma, one patient survived 10 years without recurrence until he died of newly developed osteosarcoma, and the other patient is alive without recurrence for 20 years. As the prognosis of pediatric adrenocortical carcinoma is poor, peri-operative aggressive chemotherapy is suggested in addition to radical surgery.

Adrenocortical carcinoma is a rare type of endocrine malignancy with an annual incidence of approximately 1-2 cases per million. The majority of these tumors secrete cortisol, and a few secrete aldosterone or androgen. Estrogen-secreting adrenocortical carcinomas are extremely rare, irrespective of the secretion status of other adrenocortical hormones. Here, we report the case of a 53-year-old man with a cortisol and estrogen-secreting adrenocortical carcinoma. The patient presented with gynecomastia and abdominal discomfort. Radiological assessment revealed a tumor measuring $21{\times}15.3{\times}12cm$ localized to the retroperitoneum. A hormonal evaluation revealed increased levels of estradiol, dehydroepiandrosterone sulfate, and cortisol. The patient underwent a right adrenalectomy, and the pathological examination revealed an adrenocortical carcinoma with a Weiss' score of 6. After surgery, he was treated with adjuvant radiotherapy. Twenty-one months after treatment, the patient remains alive with no evidence of recurrence.

We describe a case of a 61-year-old Korean man who was diagnosed with renal cell carcinoma that was discovered on abdominopelvic computed tomography obtained after the patient complained of back pain. A radical nephrectomy was performed, and the surgical specimen showed a relatively well-circumscribed and yellowish lobulated hard mass. Microscopically, the tumor showed sheets and nests of hypercellular pleomorphic cells with thick fibrous septation, frequent mitoses, and areas of adrenal cortical-like tissue. Immunohistochemical staining revealed that the tumor cells were positive for inhibin-${\alpha}$, vimentin, synaptophysin, and melan A. It also revealed that the tumor cells were negative for pan-cytokeratin, epithelial membrane antigen, paired box 8, ${\alpha}$-methylacyl-coenzyme A racemase, CD10, cytokeratin 7, carbonic anhydrase 9, c-Kit, renal cell carcinoma, transcription factor E3, human melanoma black 45, desmin, smooth muscle actin, S-100, chromogranin A, CD34, anaplastic lymphoma kinase, and integrase interactor 1. Based on these histopathological and immunohistochemical findings, we diagnosed the tumor as intrarenal adrenocortical carcinoma arising in an adrenal rest. Several cases of intrarenal adrenocortical carcinoma have been reported, although they are very rare. Due to its poor prognosis and common recurrence or metastasis, clinicians and pathologists must be aware of this entity.

Objective: The purpose of this study is to report a metastatic adrenocortical carcinoma patient treated with wheel balanced cancer therapy (WBCT) regimen. Methods: A 52-year-old female patient diagnosed and incised with metastatic adrenocortical carcinoma visited the East West Cancer Center (EWCC) on Sep. 1st, 2018 for WBCT. The patient was treated with WBCT for an approximately 2 months, from Sep. 1st to Nov. 9th. Computed tomography (CT) was used to follow-up the tumor site. Laboratory analysis and National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0 were used to evaluate the safety of WBCT. Results: The surgical beds after surgery (Lt. Laparoscopic adrenalectomy) were maintained without recurrence at follow up chest CT, and related symptoms and quality of life (QOL) were improved during the WBCT. Conclusion: This case study suggests that WBCT may help to improve QOL of adrenocortical carcinoma patient.

Adrenocortical carcinomas are rare and frequently aggressive tumors that may be functional (hormone-secreting) and may cause Cushing's syndrome or virilization, or non-functional and manifest as an abdominal mass. This paper reports the case of a 77-year-old woman with cortisol- and aldosterone-secreting adrenal carcinoma. The patient complained of general weakness, a moon face, and weight gain. She also had hypokalemia and hypertension. Her endocrinological data showed excessive aldosterone production and non-suppressible cortisol production in a low-dose dexamethasone suppresion test. Her abdominal CT showed a right adrenal mass. She underwent right adrenalectomy, and her histology revealed the presence of adrenocortical carcinoma. After adrenalectomy, her hypokalemia returned to normal and she is being treated with hydrocortisone.

Background: Adrenal tumors are relatively uncommon, and have different presentations, so we decided to evaluate the clinico-pathological characteristics of benign and malignant tumors in a ten-year period. Materials and Methods: This cross sectional-analytical study was conducted on adrenal resection samples taken during 2004-2014 in three hospitals in Yazd province. Data were analyzed using SPSS software, version 17. Chi-square and Fisher's exact test were used as appropriate Results: A total of 71 patients with adrenal tumors were analyzed, including 32 (45.1%) men and 39 (54.9%) women with an overall mean age $37.7{\pm}19.9$ (range: 6-75 years). Some 50.7% of lesions were benign and 49.3% were malignant. Neuroblastoma was the most malignant lesion (32.3%) followed by adrenocortical carcinoma (8.4%). Among the benign lesions pheochromocytoma was the most common (25.3%) followed by adrenocortical adenoma (12.6%). While 64% of tumors were functional 36% were non functional. Significant correlation was seen between the age of patient and type of tumor (P=0.001). In patients between 14-40 years old no malignant lesions was found, although under 14 years old all of the tumors were malignant. Malignant lesions mostly presented with abdominal pain, abdominal mass and anorexia (57.2%, 45.7% and 45.7%) respectively. Benign lesions mostly presented with paroxysmal hypertension, headache and abdominal pain (61.2%, 47.2% and 44.4%) respectively. Conclusions: Since the trend of adrenal tumors is on the rise based on this and other studies, suspected cases should undergo prompt hormonal and radiological assessment. Early diagnosis and treatment could prevent tumor progression and reduce mortality and morbidity rates.

Catheter related and perianal problems are common surgical complications encountered during the treatment of pediatric malignancies. However acute surgical abdominal emergencies are rare. The aim of this study is to review acute surgical abdominal complications that occur during the treatment of childhood malignancies. Out of a total of 1,222 patients who were newly diagnosed with malignant disease, between January 2003 and May 2008, there were 10 patients who required surgery because of acute abdominal emergencies. Their medical records were reviewed retrospectively. Hematologic malignancies were present in 7 patients (4 leukemia, 2 lymphoma, 1 Langerhans cell histiocytosis) and solid tumors in 3 patients (1 adrenocortical carcinoma, 1 desmoplastic small round cell tumor, 1 rhabdomyosarcoma). Seven patients had intestinal obstruction, two had gastrointestinal perforation and one, typhlitis. Intestinal obstructions were treated with resection of the involved segment with (N=2) or without (N=3) enterostomy. Two patients had enterostomy alone when resection could not be performed. Intestinal perforation was treated with primary repair. Typhlitis of the ascending colon was treated with ileostomy. Right hemicolectomy was necessary the next day because of the rapidly progressing sepsis. Three patients are now alive on chemotherapy and one patient was lost to followed-up. Among six patients who died, five died of their original disease progression and one of uncontrolled sepsis after intestinal perforation. Although rare, acute surgical abdominal complications can occur in childhood malignancies. Rapid and accurate diagnosis and appropriate operation are required for effective treatment of the complications.

암(예: 폐암, 전립선암, 간암, 부신겉질샘암종 등)의 조기 진단은 치료비용, 생존율, 완치 여부를 결정짓는 아주 중요한 단계다. 현재의 암 진단 시스템(예: 조직검사, 컴퓨터단층쵤영, 양전자방출단층쵤영, 자기공명영상, 초음파촬영 등)은 고가의 장비를 사용하거나 훈련된 고급 인력만이 수행 가능하기 때문에 신속한 조기 진단에 적합하지 못하다. 국제 의과학 사회는 현장검사(point of care) 디바이스 개발을 통한 효과적인 질병 관리 시스템 개발을 지향하고 있으며, 다양한 분석법 기반의 디바이스가 개발되어왔다. 이 중에서도 측면 흐름 면역 크로마토그래피 분석법 스트립은 경제적인 비용, 짧은 검사 시간, 사용자의 쉬운 접근성 등의 많은 이점들이 있다. 본 논문에서는 LFIA 스트립의 최신 연구 동향을 바탕으로 암 진단 관점에서의 비색법 기반 LFIA 스트립의 연구 방향 및 잠재적 응용에 대해 논의하고자 한다.

Objectives Aromatase inhibitors that block estrogen synthesis are a proven first-line hormonal therapy for postmenopausal breast cancer. Although it is known that standardized extract of Ginkgo biloba (EGb761) induces anti-carcinogenic effects like the aromatase inhibitors, the effects of EGb761 on steroidogenesis have not been studied yet. Therefore, the effects of EGb761 on steroidogenesis and aromatase activity was studied using a H295R cell model, which was a good in vitro model to predict effects on human adrenal steroidogenesis. Methods Cortisol, aldosterone, testosterone, and $17{\beta}$-estradiol were evaluated in the H295R cells by competitive enzyme-linked immunospecific assay after exposure to EGb761. Real-time polymerase chain reaction were performed to evaluate effects on critical genes in steroid hormone production, specifically cytochrome P450 (CYP11/ 17/19/21) and the hydroxysteroid dehydrogenases ($3{\beta}$-HSD2 and $17{\beta}$-HSD1/4). Finally, aromatase activities were measured with a tritiated water-release assay and by western blotting analysis. Results H295R cells exposed to EGb761 (10 and $100{\mu}g/mL$) showed a significant decrease in $17{\beta}$-estradiol and testosterone, but no change in aldosterone or cortisol. Genes (CYP19 and $17{\beta}$-HSD1) related to the estrogen steroidogenesis were significantly decreased by EGb761. EGb761 treatment of H295R cells resulted in a significant decrease of aromatase activity as measured by the direct and indirect assays. The coding sequence/Exon PII of CYP19 gene transcript and protein level of CYP19 were significantly decreased by EGb761. Conclusions These results suggest that EGb761 could regulate steroidogenesis-related genes such as CYP19 and $17{\beta}$-HSD1, and lead to a decrease in $17{\beta}$-estradiol and testosterone. The present study provides good information on potential therapeutic effects of EGb761 on estrogen dependent breast cancer.
