White-Eyed Orbital Blowout Fracture: A Retrospective Study of 22 Patients / 대한이비인후과학회지

Background and Objectives@#The study reports on the clinical experience of repairing white-eyed orbital blow out fracture through a retrospective study of various incidences of white-eyed orbital blow out fracture that resulted in different treatment methods and outcomes.Subjects and Method A retrospective study was performed on 22 patients with white-eyed blowout fracture who underwent operation between March 2009 and June 2019 at our clinic. Patients were divided into 2 groups by age: 6 to 12 and 13 to 18. A review of medical records included demographic data, cause of injury, preoperative symptoms, trauma to operation time and surgical outcomes including improvement of postoperative ocular symptoms and complications. @*Results@#The study population included 20 males and 2 female patients ranging from 6 to 18 years (mean, 14.2 years) of age. Fifteen of 21 patients with diplopia or limitation of eyeball movement showed a complete improvement of symptoms after surgery and 6 (28.5%) had remaining symptoms. One patient had no ocular symptom, but had oculocardiac reflex including nausea and vomiting. Two cases were re-operated due to adhesion of graft material. There was one sinus infection related to the implant. @*Conclusion@#This study shows that early reconstruction and release of incarcerated muscle within 5 days after trauma for white-eyed blowout fracture gives successful result that does not accompany major complications. All of the 22 patients who were operated for white-eyed blowout fractures had successful results.

Diagnosis and management of primary malignant melanoma of the lung: a case report / 대한내과학회지

Melanoma develops in the skin or the mucosa of organs. It spreads via lymphatic channels or the bloodstream to the regional lymph nodes or organs such as the brain, liver, and lung. Melanoma of the lung is nearly always metastatic, and primary malignant melanoma of the lung is very rare, with only 30 cases reported in the English literature. The possibility of skin lesions that have disappeared, or of undetected primary sites, makes it difficult to confirm true primary tumors. Therefore, a thorough workup is needed to make the diagnosis. Since metastatic melanoma is incurable, the goal of treatment is palliation. However, because of the rare experience of primary melanoma of the lung, it is difficult to predict the prognosis. We experienced one patient with primary malignant melanoma of the lung with metastases who had been managed with surgery, interferon-alpha, chemotherapy, and radiation therapy over 5 years. This case report presents the diagnosis and management of primary malignant melanoma of the lung.

A case of superior mesenteric artery syndrome due to peritoneal seeding in a colon cancer patient / 대한내과학회지

Small bowel obstruction can develop from adhesions, hernias, and less frequently from tumors. Superior mesenteric artery (SMA) syndrome is an uncommon cause of small bowel obstruction. We experienced a case of SMA syndrome caused by peritoneal seeding from colon cancer. A 57-year-old woman presented with nausea, post-prandial vomiting, and weight loss. She had been receiving palliative chemotherapy for 12 months to treat colon cancer with peritoneal seeding. Abdominal computed tomography and a small bowel series revealed typical findings of SMA syndrome. As conservative treatment including nutritional support and positional change was ineffective, she was treated surgically. An adhesive mass compressing the SMA and duodenum was found at the third portion of the duodenum. The pathologic diagnosis was metastatic adenocarcinoma of colorectal origin. Adhesiolysis and duodenojejunostomy relieved her symptoms. This case shows that SMA syndrome can develop via peritoneal seeding in cancer patients.

A case of the primary ovarian malignant melanoma arising from a cystic teratoma / 대한내과학회지

Primary malignant melanoma arising in a cystic teratoma of ovary is extremely rare. Approximately 25 cases of primary malignant melanoma arising from a cystic teratoma in ovary have been reported in the literature. The malignant transformation of benign cystic teratoma of ovary usually develops unilaterally in postmenopausal women. The common presenting symptoms are abdominal distention, lower abdominal pain and a palpable abdominal mass. We report a case of primary malignant melanoma of ovary in a 45-year-old patient who underwent laparotomy for evaluation of a cystic mass in right ovarian cystic teratoma. Histopathological examination of the cyst showed that it was melanoma with pre-existed teratomatous components. Extraovarian primary site was not found. Nine years after the excision, brain metastases developed which were pathologically confirmed as metastatic melanoma. The patient subsequently developed pulmonary metastases and received immunochemotherapy consisting of cisplatin, dacarbazine, vinblastine, interleukin-2 and interferone-alpha. She is on a regular follow-up and continues to have stable disease for 9 months.
