An incidentaloma is a tumor found incidentally without clinical symptoms or suspicion; the lesion may be adrenal, pituitary, or thyroidal. We report the case of an asymptomatic individual with preoperatively undiagnosed pheochromocytoma (size: 4.86 cm) that was revealed using elective nonadrenal surgical procedures. The patient demonstrated peri- and post-operative hypertensive crisis and tachycardia. Three days after the dramatic onset of symptoms, the patient expired due to pulmonary edema, multiple organ failure, and terminal sepsis, despite administration of extracorporeal membrane oxygenation-assisted cardiopulmonary resuscitation. A left medial kidney mass obtained at autopsy confirmed pheochromocytoma.

Fitz-Hugh-Curtis syndrome has been described as perihepatitis associated with pelvic inflammatory disease (PID). It is classically seen in premenopausal young women who have right upper quadrant pain, usually but not always accompanied by symptoms of PID, and is frequently confused with biliary tract disease. However, the syndrome has rarely been reported in males. The predominant symptom is right upper quadrant pain, but PID may not be present in male patients. Here, we report a case of Fitz-Hugh-Curtis syndrome in a young male patient, which was diagnosed by serological tests and computed tomography. Fitz-Hugh-Curtis syndrome should be considered as a possible cause of pain in the right upper quadrant in male patients, although such a case is very rare.

Historically, the standard treatment for early-stage cervical cancer has been radical surgery in patients with operable disease. Patients with locally advanced disease (defined as FIGO stage IB2 and usually with tumors greater than 4 cm, IIB, III and IVA) are usually treated with radical radiotherapy, which consists of external beam radiotherapy and internal brachytherapy. However, the discovery that cervical cancer tumors are sensitive to chemotherapy led to the initiation of studies looking at adding chemotherapy to both radiotherapy and surgery. Following a National Cancer Institute (NCI) alert in 1999 (NCI 1999), chemoradiotherapy became the standard of care for women with locally advanced cervical cancer.

The hepatic artery can have numerous variations. However, a common hepatic artery originating from the left gastric artery and the entire hepatic blood supply furnished by the left gastric artery is an extremely rare anomaly. We encountered this anomaly in a patient with advanced gastric cancer. A surgeon should recognize this image appearance and identify the anomaly. Without knowledge of this anomaly and given the strategy for extensive lesser sac dissection generally employed during gastric cancer surgery, a surgeon could easily inadvertently divide this vessel, resulting in critical liver damage. We report a case of common hepatic artery originating from left gastric artery and review of the literatures.

Endometriosis is an estrogen-dependent chronic inflammatory condition that affects women in their reproductive period and is associated with pelvic pain and infertility. Oxidative stress (OS) occurs when reactive oxygen stress (ROS) and anti-oxidants are in imbalance. OS is a potential factor involved in the pathophysiology of endometriosis. Iron-induced ROS may trigger a chain of events resulting in the development and progression of endometriosis. Endogenous ROS are correlated with increased cellular proliferation and ERK1/2 activation in human endometriotic cells. An oxidative environment leads to stimulation of the ERK and PI3K/AKT/mTOR signaling pathways that facilitate endometriotic lesion progression through adhesion, angiogenesis, and proliferation. OS is also known to be involved in epigenetic mechanisms in endometriosis. We summarize the recent knowledge in our understanding of the role of oxidative stress in the pathogenesis of endometriosis.

Hot flush (hot flush or facial flush) is the most frequent symptom experienced by women of peri-menopausal age. It may appear on women or even men after surgery or chemotherapy. Hot flush is one of the biggest reason for women to undergo hormone replacement therapy (HRT). It also crucially affects various aspects of life quality such as occupation, social life, daily routine and health awareness. The most effective and fundamental remedy for hot flush is HRT. However, a few women is not responsive to HRT and investigation to elucidate other causes of hot flush is warranted, especially in elderly. The contraindications such as breast cancer mandates other modality of treatment. Variety of treatment for hot flush other than HRT will be discussed herein.

Langerhans cell histiocytosis (LCH) is commonly characterized by abnormal function and differentiation or proliferation of monocytes. In LCH, granulomatous lesions, including langerine-positive histocytes and inflammatory infiltrates, can occur to all tissues, particularly well in the bones, skin, lungs, and pituitary gland. In case of external auditory canal LCH, conductive hearing loss may occur, and the most common symptom is otorrhea. Here we present a case that 49-year-old male with external auditory canal mass. Since no invasive findings were seen in radiologic study, endoscopic transcanal excision was performed and LCH was proven by pathologic report. We present this case of external auditory canal LCH with the review of literature.

Colorectal cancer (CRC) is the third most common cause of cancer-related death in the world. Although the long-term outcome of patients with metastatic CRC is still poor, target therapy including anti EGFR agents and anti VEGF agents and immunotherapy including anti PD-1 antibody and anti CTLA-4 antibody have shown clinical benefits in the treatment of patient with metastatic CRC. In the future, the personalized treatment strategy based on the clinical characteristics and biologic features of patients with metastatic CRC will be necessary. In this review, we summarized the mechanisms and clinical evidences of target therapy and immunotherapy, and the guideline of clinical practice in patients with metastatic CRC.

Objectives: The study aimed to compare the indicators of infrastructure of the whole country with those of Busan through National Medical Care Psychiatric (hospital level) Quality Assesment and to provide the basic evidence for presenting vision and strategies of mental health policy. Methods: National Medical Care Psychiatric (hospital level) Quality Assesment Data was used from 2011 to 2015. A total of 8 indicators were analyzed including facility and workforce. Results: The median value of the capacity per ward was decreasing with years both whole country and Busan. The number of beds out of total inpatient occupancy was improved over the years. There was no clear change in the number of inpatients per toilet in the hospitalized ward, but the indicator was decreasing obviously. Therefore, the median value of whole country and Busan was same with 10.2 in 2015. Conclusions: We confirmed that indicators for infrastructure were improving in a generally positive change over the years. The infrastructure is related to the patient-centered treatment environment, and the workforce is related to the quality of care. Therefore, the structural area should be continuously evaluated and improved.

Malignant peripheral nerve sheath tumor (MPNST) is one of the soft tissue sarcoma believed to originate from neural crest cells. The patients with neurofibromatosis type I (NF1) have about 8-13% of the lifetime risk of the malignant transformation. Neurofibroma on patients with NF1 can be surgically resected and has good prognosis if approach to the tumor is possible. We experienced a case of a 50-year-old woman with NF who had incompletely resected neurofibroma, which presented a rapid malignant transformation to MPNST, 3 months after the first surgery. We reported this case with a brief review of literature.
