A 59-year-old man was admitted with general fatigue, an epigastric mass, and remittent fever. Radiological examinations disclosed a huge solid-to-cystic mass in the right lobe of the liver, and the mass severely compressed the right diaphragm, the inferior vena cava, and the right atrium. In addition, the patient suffered from chronic hepatitis; however, the serum alpha-fetoprotein, carcinoembryonic antigen, and PIVKA II levels were all within the normal ranges. The serum C-reactive protein level was 7.71mg/dl. With a clinical diagnosis of a malignant hepatic tumor invading the right diaphragm, surgery was performed. The tumor originated from segments IV and VII of the liver, was well defined, and grew extrahepatically. The tumor was resected using an ultrasonic cavitational aspirator together with the infiltrated right diaphragm. The resected tumor measured 23 x 13 x 23cm in size and weighed 3,700 g. Histologically, the tumor was found to consist of hepatocellular carcinomatous component and sarcomatous component. In the sarcomatous component, spindle-shaped cells which were positive for the immunohistochemical localization of vimentin, alpha-smooth muscle actin, and keratin were identified. The postoperative course was uneventful. The value of the serum C-reactive protein returned to within the normal range, and the patient became afebrile. The patient received a postoperative combination chemotherapy (etoposide, epirubicin, and cisplatin), and remains well with no signs of recurrence 12 months after the operation.

A 70-year-old Japanese man presented to our hospital with a 1-month history of progressive general fatigue and anorexia. A physical examination revealed severe anemic condition, mild persistent splenomegaly, and no palpable surface lymph nodes. He had pleural effusion and ascites, though no malignant cells were detected in the effusion. He eventually died without any diagnosis of his disease. Immunohistochemical staining of his tumor after autopsy showed atypical cells that were negative for epithelial membrane antigen (EMA), keratin (AE1/3), keratin-20, vimentin, factor VIII, leukocyte common antigen (LCA/T200; CD45), myeloperoxidase (MPO), terminal deoxynucleotidyl transferase (TdT), lysozyme, CD1a, CD3, CD4, CD10, CD15, CD20 (L26), CD21, CD23, CD34, CD43, CD56, CD68, CD79a, CD138, and EBER-1 in situ. Only a few scattered cells expressed CD30, but they showed no staining for anaplastic large-cell lymphoma kinase (ALK). A few scattered cells expressed S-100 antigen and the majority of cells dominantly expressed dendritic cell-associated antigens (CD35, FDC, Ki-M1p). In conclusion, we found this unknown primary tumor to be consistent with a follicular dendritic cell tumor with anaplastic features.

Squamous cell carcinoma of the extrahepatic bile duct is quite rare. A 77-year-old woman with jaundice and general fatigue was referred to our hospital. Multiphase contrast-enhanced computed tomography visualized a 17-mm solid mass in the junction of the cystic and common bile ducts. The patient underwent pylorus-preserving pancreaticoduodenectomy. The pathological findings demonstrated keratin-positive poorly differentiated squamous cell carcinoma of the extrahepatic bile duct (T3N0M0, stage IIIA). Although adjuvant chemotherapy with gemcitabine was administered, the patient exhibited local recurrence at the site of anastomosis of biliojejunostomy 20 months after resection and died 32 months after resection.

Endurance athletes are susceptible to cellular damage initiated by excessive levels of aerobic exercise-produced reactive oxygen species (ROS). Whilst ROS can contribute to the onset of fatigue, there is increasing evidence that they play a crucial role in exercise adaptations. The use of antioxidant supplements such as vitamin C and E in athletes is common; however, their ability to enhance performance and facilitate recovery is controversial, with many studies suggesting a blunting of training adaptations with supplementation. The up-regulation of endogenous antioxidant systems brought about by exercise training allows for greater tolerance to subsequent ROS, thus, athletes may benefit from increasing these systems through dietary thiol donors. Recent work has shown supplementation with a cysteine donor (N-acetylcysteine; NAC) improves antioxidant capacity by augmenting glutathione levels and reducing markers of oxidative stress, as well as ergogenic potential through association with delayed fatigue in numerous experimental models. However, the use of this, and other thiol donors may have adverse physiological effects. A recent discovery for the use of a thiol donor food source, keratin, to potentially enhance endogenous antioxidants may have important implications for endurance athletes hoping to enhance performance and recovery without blunting training adaptations.
