[A new case of hepatic adenomatosis treated with orthotopic liver transplantation]. / Un nouveau cas d'adénomatose hépatique traité par transplantation hépatique orthotopique.

Hepatic adenomatosis is a rare disease with multiple hepatic adenomas (10 or more), not associated with an history of oral contraceptive use or anabolic steroids use or with glycogen storage disease. A new case is reported in a 23 year-old woman who consulted for an abdominal mass and who had more than 50 adenomas of the liver. The suspicion of malignant transformation by the elevation of the alpha-foetoprotein, and the diffuse affectation of the liver, with minimum free parenchyma, suggested to carry out an orthotopic liver transplantation. The definitive histological examination of the surgical specimen confirmed the existence of local areas of hepatocellular carcinoma.

Solitary adrenal gland metastasis of a follicular thyroid carcinoma presenting with hyperthyroidism.

Follicular thyroid carcinoma typically manifests under euthyroid conditions, and diagnostic scintigraphy usually identifies a cold nodule. Sometimes, such tumors can appear in the context of hyperthyroidism, which can be caused by a toxic multinodular goitre, a toxic adenoma, or even carcinoma. We report a case of follicular thyroid carcinoma discovered after surgical treatment of a toxic multinodular goiter, in which solitary adrenal gland metastasis was detected five years later. A (131)I whole body scan is the diagnostic method of choice for functioning thyroid metastasis.

The importance of a tumor capsule in columnar cell thyroid carcinoma: a report of two cases and review of the literature.

Two cases of papillary columnar cell thyroid carcinoma are presented. A 49-year-old man presented with lymph node and pulmonary metastases at diagnosis; a 51-year-old woman developed local recurrence and lung and bone metastases 3 years postsurgery. Death occurred after 52 and 57 months, respectively. The first case lacked a tumor capsule, although the second exhibited capsule remains with extensive tumor cell infiltration. A review is made of all similar cases reported to date in the literature, placing emphasis on the epidemiological and prognostic differences observed in terms of circumscribed or noncircumscribed tumor. The presence of a capsule was associated with a higher frequency of female patients and a favorable prognosis. In contrast, tumors profusely infiltrating the thyroid parenchyma or extrathyroid tissues in the absence of a capsule, found in similar proportion of men and women had a fatal prognosis.
