Hepatocellular Carcinoma in a Patient with Tetralogy of Fallot: A Case Report and Literature Review.
We herein report a 34-year-old woman born with tetralogy of Fallot who had undergone 5 cardiac repair procedures. She developed liver nodules with congestive cirrhosis secondary to severe mitral regurgitation and an atrial septal defect. A percutaneous liver biopsy showed hepatocellular carcinoma with liver fibrosis, which was treated using transarterial chemoembolization.

We present three cases with an atypical clinical course of organizing pneumonia (OP) secondary to coronavirus disease 2019 (COVID-19). Three patients were discharged with satisfactory improvement after standard steroid therapy for COVID-19. Shortly after the completion of treatment, the patients experienced a flare-up of symptoms. ⋯ Steroids were administered, and a good therapeutic response was observed. This report is the first to describe pathologically confirmed OP that developed after recovery from COVID-19. Careful follow-up is advisable for patients who have recovered from COVID-19.

Disseminated intravascular coagulation (DIC) is the most frequent coagulation disorder associated with solid tumors, including prostate cancer. We herein report a 76-year-old man who suffered from intramuscular bleeding of the right gluteus maximus. Laboratory data showed a pattern of DICwith enhanced fibrinolysis, and a general examination led to the diagnosis of advanced prostate cancer with multiple bone metastases. To our knowledge, this is the first report describing intramuscular bleeding as an initial manifestation of prostate cancer with DIC with enhanced fibrinolysis.

Atypical Shone's complex is a rare congenital anomaly involving a left-sided obstructive lesion of two or three cardiovascular levels. A 70-year-old man with dyspnea on exertion was diagnosed with severe aortic stenosis (AS) with a bicuspid valve, complicated by severe aortic coarctation (CoA) and a double-orifice mitral valve. He underwent surgery for AS and CoA in one session. It is important to search for complicated malformations, even in cases of bicuspid aortic valve found in old age.

A 36-year-old man experienced severely impaired consciousness twice after drinking because of hyperammonemia. No abnormal blood tests were found other than ammonia levels. However, magnetic resonance imaging (MRI) showed atrophy of the brain parenchyma. ⋯ Urea cycle disorders (UCDs) were assumed to be involved. Genetic testing revealed a monoallelic mutation of the carbamoyl phosphate synthase 1 (CPS1) gene. When transient hyperammonemia of unknown cause occurs repeatedly in adults, an active investigation for UCDs should be conducted.
