[Early detection of synchronous thyroid carcinoma and malignant melanoma by fluorodeoxyglucose positron emission tomography]. / Detection précoce d'un carcinome thyroïdien et d'un mélanome malin synchrones par une tomographie par emission de positron a la fluorodeoxyglucose: cas clinique.

Functional tumor imaging using Fluorodeoxyglucose positron emission tomography (FDG-PET) is a new method in clinical oncology. The 18 FDG, is a glucose analog that accumulates in cells in proportion to the rate of glucose metabolism, and increased carbohydrate metabolism has been recognized as a feature of malignant cells versus normal cells. In addition, it permits the detection of metastases or synchronous tumours not discovered by anatomic imaging. Although detection of the primary site of disease is usually accomplished well with conventional techniques, the performance of FDG-PET may be useful to determine tumours that are not clinically evident. The authors describe a case of early detection of synchronous thyroid carcinoma by FDG-PET in a young patient opereted on for a malignant melanoma on his arm.

Primitive abscess of the great epiploon: clinical case and literature review.

BACKGROUND: The primitive abscess of the great epiploon often poses a pre-operative diagnosis problem. The clinical picture associates an abdominal pain and an inflammatory syndrome. METHODS: The diagnosis is essentially based on the imaging data and the exploratory laparoscopy. The treatment consists in performing a drainage of the abscess and an epiploic resection "on demand" preserving healthy tissues, as well as giving antibiotics. RESULTS: The patient has been treated successfully by coelioscopy and a partial epiploic resection was performed with uncomplicated post-operative outcome. CONCLUSIONS: The primitive abscess of the great epiploon remains a rare pathology of uncertain etiology. The coelioscopy is the best method to rectify or to comfirm pre-operative diagnosis and to perform treatment avoiding the inconveniences of the laparotomy.
