A Case of Primary Anti-Phospholipid Syndrome with Recurrent Renal Infarction / 대한내과학회지

Anti-phospholipid syndrome is characterized by the occurrence of venous or arterial thrombosis in the presence of anti-phospholipid antibodies and is associated with morbidity during pregnancy. Arterial thromboses are less common than venous thromboses and most frequently manifest with features consistent with ischemia or infarction. Only a few cases of arterial thrombosis with primary anti-phospholipid syndrome have been reported in Korea. We report a 41-year-old man with anti-phospholipid syndrome who had abdominal pain due to a recurrent renal infarction, and we review the literature on anti-phospholipid syndrome.

A Case of Invasive Thymoma with Endotracheal Polypoid Growth / 결핵및호흡기질환

Thymomas are one of the most common neoplasms of the mediastinum derived from thymic epithelium. It is common that invasive thymoma invades the lung, pericardium, and great vessels. Airway compression by mass effect also occurs, but direct polypoid tumor growth into the airway is extremely rare. Only 20 cases of invasive thymoma with endobronchial polypoid growth have previously been reported globally. However, there is no case report of invasive thymoma with endotracheal growth. Herein, we report a rare case of invasive thymoma with endotracheal polypoid growth in a 28-year-old woman.

A Case of Chronic Renal Failure after Exposure to Oral Sodium Phosphate Bowel Purgatives / 대한내과학회지

Renal failure due to nephrocalcinosis after large-bowel cleansing with sodium phosphate preparations before endoscopic procedures is an easily overlooked diagnosis. While it has been reported that acute renal failure can result from the use of oral sodium phosphate preparations, chronic renal failure has not yet been reported. We report a case of chronic renal failure due to oral sodium phosphate, in which a kidney biopsy was performed.

A Case of Intracardiac Thymic Carcinoma Presenting as Congestive Hepatopathy / 대한내과학회지

Thymic carcinoma is a rare but aggressive epithelial neoplasm with a strong propensity for early local invasion and widespread metastasis. It is common for thymic carcinomas to invade the lungs, pericardium, and great vessels. However, invasion of thymic carcinoma into the right atrium, right ventricle, mediastinum, and superior vena cava is very rare. There have been sporadic reports on intracardiac thymic carcinomas globally and only one case report in South Korea to date. We herein report a case of intracardiac thymic carcinoma presenting as right-sided heart failure with congestive hepatopathy.
