Sarcomatoid carcinoma is a rare tumour composed of intermingled malignant epithelial and mesenchymal cells, and it has been reported in various organs including the liver. Sarcomatoid cholangiocarcinoma (CCC) is an extremely rare liver primary tumour. Here, we report a case of an elderly man who was admitted to our hospital after head trauma. He performed a head CT that diagnosed cerebral metastasis. On abdominal CT, he presented a 10×8×9 cm-sized hypodense liver mass in the VII and VIII segments, with peripheral enhancement. Histological and immunohistochemical examination of the tumour showed a malignant neoplasm with both carcinomatous and sarcomatous components and positive expression of cytokeratin and vimentin antibodies. The patient was diagnosed with intrahepatic sarcomatoid CCC at an advanced stage and died 45 days after the diagnosis. We emphasise the importance of immunohistochemistry which may provide a clue to proper diagnosis.

Introduction: Abdominal tuberculosis frequently mimics other conditions such as inflammatory bowel disease, sarcoidosis, advanced ovarian tumour, lymphoma, mesothelioma or carcinomatosis. Case Report: The authors report the case of a 19-year-old woman with fever, abdominal pain and history of right pleural empyema. Laboratory findings showed anaemia, lymphopenia and positive interferon-gamma release assay. Computed tomography findings included apical lung nodules, pleural thickening, right pleural effusion and ascites. Treatment for suspected tuberculosis was started. Two months later, computed tomography showed peritoneal thickening causing liver scalloping. Fluid collection from a peritoneal fluid-filled nodule confirmed the diagnosis. Conclusion: Visceral scalloping is a common finding of carcinomatosis

The authors report a case of a 75-year-old woman who presented to the Emergency Department with dyspnoea, productive cough, vomiting and unquantified weight loss. She denied fever, night sweats or other symptoms. She had a past history of dementia, dyslipidaemia and right total hip replacement. No relevant family history was known. On physical examination, the patient was fully awake, relatively mobile and disoriented to place and time. Her vital signs were within normal limits with an oxygen saturation of 94% on room air. Lung examination revealed absence of breath sounds over the right hemithorax with increased dullness to percussion. Bilateral pitting oedema extending to the joints was seen in the lower extremities. She complained of pain while palpating both femurs. Digital clubbing was also notable (Figure 1A). Laboratory findings were as follows: haemoglobin 13.7 g/dL (normal, 12-15), mean corpuscular volume 82.6 fL (normal, 83-101), leucocytes 13.7x10 9 /L (normal, 4-10), platelets 310x10 9 /L (normal, 150-400), lactate dehydrogenase 442 U/L (normal, 125-220), C-reactive protein 4.97
