The authors describe the case of mesiodens in two non-identical twins and in their grandfather. They recall that, although no investigation confirmed the hereditary nature of the mesiodens, it is quite undeniable in view of the frequency of familial cases. They think there is a recessive gene on an autosome and a gene on the inhibiting chromosome X. They discount the theory of mutation.

We described the sonographic, computed tomographic (CT), and magnetic resonance (MR) imaging features of one atypical case of nodular regenerative hyperplasia of the liver. The presence of multiple hepatic nodules suggested the diagnosis of metastatic disease to the liver because of a peripheral rim of enhancement on CT obtained after intravenous administration of contrast material and a halo sign on T2-weighted spin-echo MR imaging. Examination of the pathologic specimen obtained after surgical biopsy showed that the nodules were made of hepatocytes, with a nodular arrangement surrounded by peliosis, without fibrosis or cirrhosis. These findings suggested that peliosis may cause peripheral rim of enhancement on CT and halo sign on MR imaging. In light of this case, nodular regenerative hyperplasia of the liver should be considered in the differential diagnosis of hepatic metastases.
A case of "cryptogenetic osteolysis of the mandible" is reported. This is a rare affection as only 13 cases of "phantom mandible" are known, but other sites exist (91 cases of phantom bone are known). The diagnosis is suspected after radiography, and confirmed by anatomopathological examination. No treatment for this affection has been described.
