Adenoameloblastoma is a rare odontogenie tumor of which only three cases w‘t~r~ reported by Masaki (two eases, 1939) and by Ito and associates (one case, lR57) in .Iapar~. The author reports the case of a tumor the size of a chicken egg, occurring in thtb anterior region of the left mandible in a 17.year-old girl. JIicroscopicall!; Ilo\2 Clinicall>-, the tumor was suspectetl of being a follicular cyst. ever, it was found to be a compact mass of many ill-defined nestlike aggregates of cell>, The cells in some of the aggregates were each with a round or spindle-shaped nucleus. loosely arranged and stellate in form. The tumor tissue hat1 lime salts deposited herc~ and t,here in it, the cells collected in its different portions looking glandular in struc:turla. The picture was indicative of an adenoameloblaston~a. The tumor in this case may have originate<1 from the primitive oral epitl-~t~lirl~tl matle allerrant before its differentiation. K. H. ‘1’.

Tumors of a glandular nature occurring on the tongue have, for many years, been lumped together in the category of mixetl tumors. A series of forty-three glanduhtr tumors, many of which had previously been diagnosed as mixed tumor, were classified into four groups on the basis of their histologic pattern. Cylindromas accounted for 51 ptar cent; mucoepidermoids, 26 per cent ; and adenocarciuoma, 21 pcxr cent,. Only one niistxil tumor was found in the series. All of the tumors with the exception of mixed tumors, must be considered as malignant, since they have proved to be capable of distant metastasis. Excellent, results followecl radical surgical operations. T. .T. C-1.

1959. The author presents an interesting ease in which an 11-year-old boy was found to have painless swelling of the mandibular left alveolus. X-ray examination revealed a lesion which involved the whole width of the mandible, extending from the alveolus to the lower border. The biopsy report indicated giant-cell reparative granulomn. An operation was performed by an intraoral flap procedure. A cavity was prese’nt after removal of the tumor, and this was packed with bone chips made from “(luicl

Fractures of the zygoma are reported as being rare. “The zygoma is the heaviest hone in the face and when subjected to direct trauma, it usually dislocates from the zygomatic process of the temporal bone, the angular process of the frontal bone, and the maxilla. Following separation, the zygoma acts as a missile, moving through the center of the face, where it may smash the fragile bones in its path.” Partial trismus is suggestive of a depressed zygomatic arch. Reduction of a fractured zygoma should be done, m-hen possihlo, before the ninth {lay. T. J. C.
