The history of most cutaneous squamous cell carcinomas (CSCC) is limited to the skin. However, about 4% of these malignancies are at risk of metastasis and can be life-threatening. This risk is determined by clinical and histological elements which are individually recognized, but so far staging systems allow us neither to assess a risk score, nor to adopt a standardized therapeutical approach. This article reviews prognostic factors for CSCC, and underlines the need for the clinician to have all clinical and histological elements available, in order to try to define the best therapeutical strategy for each case, following up-to-date recommendations.

There are numerous variants of cutaneous tumors involving the eyelids. Tumors of a different nature may at times be observed simultaneously in the same area of the eyelid. A clinicopathologic case of a 36-year-old male patient with 2 different cutaneous tumors at the nasal part of the left eyelid is reported. One was a nodular tumor on the inner canthus with a pearly appearance; the other had a papillomatous pattern. After surgical removal, the histopathological study of the tumors disclosed a typical basal cell carcinoma and a squamous cell papilloma. Both tumors can be commonly observed on the eyelids and surgical excision cured the patient.

Basal cell carcinoma of the skin is the most common human cancer. It is also the most frequent malignant tumor of the eyelid. In Europe, its most common clinical presentation is a hard indurated, and sometimes ulcerated nodule. The authors report a giant palpebral basal cell carcinoma in a black non albinos Cameroonian patient. The ethnic origin, localization and macroscopic aspect are discussed. The problems connected with diagnosis and treatment of malignant tumors in Africa are noted.

INTRODUCTION. Une augmentation de l'incidence du carcinome hépatocellulaire (CHC) a été constatée dans les pays occidentaux ces dernières années. Il fait parti des cinq premières causes de mortalité dans le monde. Il se développe généralement sur une cirrhose, moins fréquemment sur une hépatopathie non cirrhotique et plus rarement sur un foie sain. La gravité de la cirrhose est évaluée notamment par le score de Child-­‐Pugh, puis le traitement adéquat est défini selon la classification du Barcelona Clinical Liver Cancer (BCLC). Depuis 2008, le service de chirurgie viscérale du CHUV a introduit un nouveau test quantitatif et qualitatif d'évaluation hépatique pré-­‐opératoire qui comprend une clairance au vert d'indocyanine (ICG), agent biologique qui ne change pas lors de son métabolisme hépatique. C'est un test de rétention qui nous permet de mieux évaluer les réserves hépatiques chez les patients cirrhotiques. OBJECTIF. L'objectif de ce travail est d'évaluer rétrospectivement sur la base de dossiers médicaux de malades tous les cas opérés de CHC dans le service entre 2008 et 2012, qui ont eu une évaluation pré-­‐opératoire selon le score de Child-­‐Turcotte-­‐Pugh (CTP) et de Barcelona Clinical Liver Cancer (BCLC)) en les comparant avec l'ICG test et les critères de Makuuchi. METHODE. Analyse statistique de la mortalité et de la morbidité de ces 2 groupes de patients. RESULTATS ESCOMPTES. Comparer nos résultats avec ceux publiés dans la littérature récente par les centres spécialisés pour la chirurgie hépatobiliaire. CONCLUSION. La chirurgie hépatique chez les patients cirrhotiques ne se limite plus à la chirurgie d'hypertension portale. L'amélioration des tests pré-­‐opératoires nous a permis de mieux choisir les patients accessibles à une chirurgie de résection, vu que la mortalité sur la liste d'attente de transplantation hépatique pour les patients atteints de CHC avoisine 8% par année.

L'étude porte sur 951 porteurs d'un cancer primaire bucco-pharyngo-laryngé, et révèle un taux de multifocalité du carcinome épidermoïde sur les voies digestive supérieure (bouche-pharynx-oesophage) et aérienne distale (larynx-trachée-bronches) s'élevant à 14,5 %. Les secondes localisations peuvent être simultanées (6,4 %) ou successives (8,1 %) à la découverte du premier cancer: dès la deuxième année du follow-up leur incidence dépasse celle des récidives. Elles se localisent tant au niveau ORL (8,5 %) qu'oesophagien (3 %) ou bronchique (3 %). Le cancer du voile présente un taux de multifocalité particulièrement élevé (51 %). Les auteurs décrivent un type d'endoscopie de dépistage (bucco-pharyngo-oesophago-laryngo-trachéobronchoscopie) dont la fiabilité repose sur une technicité spécifique d'une part, et sur la connaissance des caractéristiques propres aux secondes localisations d'autre part. Ce dépistage systématique permet de détecter les tumeurs secondaires à un stade le plus souvent précoce et encore asymptomatique.

The treatment of the hepatocellular carcinoma (HCC) is multidisciplinary. Hepatic transplantation offers the best chances of survival for patients with hepatic cirrhosis and HCC. However the indications for transplantation are limited. For patients that do not qualify for liver transplantation, surgical excision and percutaneous ablative treatment can also be curative. Five years survival then reaches 50%. The choice of treatment is based upon the patient's clinical state, the hepatic function and the cancer clinical stage. Follow-up is crucial as recurrences can be treated by following similar algorithms. The efficacy of oncological adjuvant and neoadjuvant treatment is not yet proved.

We report here the case of a 55 year old female that underwent surgery for a well differentiated squamous cell carcinoma of the esophagus (middle third). Four months after surgery, she complains of neck pain, for which she is prescribed non steroidal antiinflammatory drugs (NSAID). A CT-scan and a Barium swallow are then normal. After three weeks of treatment, the patient is admitted on emergency to the Intensive Care Unit for a resuscitation hematemesis and atrial fibrillation with a fast ventricular response. The symptoms are stabilized after the transfusion of a few packed red blood cells. A few hours later, however, a massive hematemesis recurs and the patient dies despite intense resuscitation measures. Autopsy reveals three gastric ulcers, one of which had perforated through the cardiac left ventricular wall

Merkel Cell Carcinoma (CCM) is an aggressive cutaneous tumor of the elderly, which has become the second cause of mortality linked to skin cancer. This has led clinicians and scientists to devote more time to the study of this rare tumor, announcing to a revolution in our understanding, diagnosis and therapy of this cancer. We present here these recent advances, which illustrate the exponential growth of knowledge in the medical field, drawing comparisons with more frequent cancers such as melanoma and squamous cell carcinoma.

The principal treatment for bleeding oesophageal varices is endoscopic ligation. Non-cardioselective beta-blockers are the gold-standard of primary prophylaxis. The principal treatment for ascites is a salt-free diet and diuretics, mainly spironolactone, if necessary associated with a loop diuretic. In refractory ascites, paracentesis or installation of a transjugular intrahepatic portosystemic shunt (TIPS) are two possible treatment options. Cirrhosis patients are at higher risk of developing hepato-cellular carcinoma. Surgery is only possible in a small number of cases. Percutaneous destruction techniques have nearly the same survival rate as that obtained by surgery and should be proposed to patients where surgery is not an option.

Hepatocellular carcinoma (HCC) is one of the most frequent malignant tumors worldwide and its incidence has increased over the last years in most developed countries. The majority of HCCs occur in the context of liver cirrhosis. Therefore, patients with cirrhosis and those with hepatitis B virus infection should enter a surveillance program. Detection of a focal liver lesion by ultrasound should be followed by further investigations to confirm the diagnosis and to permit staging. A number of curative and palliative treatment options are available today. The choice of treatment will depend on the tumor stage, liver function and the presence of portal hypertension as well as the general condition of the patient. A multidisciplinary approach is mandatory to offer to each patient the best treatment.
