Surely some cases of cancer, and probably also certain cases of o,steitis, are capable of simulating this type of neoplasm. The other main type, a uniform growth, has two variants, a pure osteolytic tumor and a trabeculated one. Roentgenologically the former cannot be distinguished from certain other semimalignant and malignant tumors, neither is it possible definitely to distinguish the latter roentgenologically from a few other known t.ypes of neoplasms mentioned by the author. The author therefore holds that in the absence of other typical skeletal findings it is not possible to make a clear-cut positive x-ray diagnosis of a plasmocytoma of the jaws. Idiopatisk

A review of the literature suggests that the roentgenology of idiopathic tooth resorptions has received insufficient attention. The author gives a description of the roentgen picture on t.he basis of 11 cases, in 3 of which more than one tooth was involved, namely, in one case 4, in one 3, and in one 2 teeth. Three teeth of one of the patients were also examined histologically. In all three of them the lesion most probably commenced in the periphery of the root. It is often difficult, or not po,ssible, clinicoroentgenologically to differentiate the internal from the peripheral form. The treatment and prognosis of these lesions are briefly discussed.

The author describes a case of a semimature cementoblastoma, the size of a pigeon’s egg, in a “l-year-old man. The tumor had originally been diagnosed as a fibro-osteoma. He discussed the differential roentgen diagnosis of cementoblastomas of this type, and in which respects they differ from other similar hard tissue tumors.
