A patient with a completely calcified chromophobe adenoma is reported. Endocrine evaluation revealed very high prolactin levels. Such extensive calcifications in prolactin-secreting adenomas are extremely rare. The possible pathogenetic mechanisms of this association are discussed.

Chordomas are extremely rare among the spinal tumors in pediatric age. The sacrococcygeal region is the typical site of such a lesion. A case of spinal chordoma in a child 4 years old, at the T12-L1 level, is reported. The tumor was surgically removed and a local radiotherapy was performed, but 9 months later spreading of lung metastases was observed. The unusual site along the vertebral column and the metastatic potential of this tumor are discussed. The very few cases reported in the literature were analyzed.

We report two cases of basicranial chondrosarcomas. Intracranial chondrosarcomas are particularly rare, amounting to 0.15% of all intracranial tumours. Their most frequent location is the skull base (76.19%), and more precisely the middle cranial fossa, as they arise from the spheno-occipital synchondrosis. Some intracerebral chondrosarcomas have also been reported. We also refer shortly to another kind of malignant cartilaginous neoplasm that was recently identified by Lichtenstein and Bernstein (1959). This is the mesenchymal chondrosarcoma. Fifteen cases of this have been reported.

Early traumatic epilepsy, whose frequency is rather high, especially in children, is usually characterized by focal motor seizures (57%) or by generalized seizures (43%). The association of both running and laughing fits in the same patient on the contrary is quite exceptional, as only three cases have been reported in literature. There are no observations about temporal lobe epilepsy, nor, particularly, about running or laughing fits in early traumatic epilepsy. We report here the interesting case of a boy whose early traumatic epilepsy manifested itself as temporal lobe epilepsy characterized by running and laughter.
